电子烟介绍(Introduction of e-cigarettes)

电子烟介绍（Introduction of e-cigarettes）电子烟介绍(Introduction of e-cigarettes)E-cigarettes are also known as virtual cigarettes and electronic atomizer for smoking cessation and replacement cigarettes. It has the same appearance as the cigarette, the taste of the cigarette, even more than the average cigarette, and it can smoke, smell and feel like a cigarette. Electronic cigarettes contain no other harmful ingredients, such as tar or aerosol particles, and manufacturers also believe that e-cigarettes are not filled with second-hand smoke. But some studies suggest that e-cigarettes still have secondhand smoke. Because the electronic cigarettes has been a lack of systematic clinical trial data to support, some countries have decided that electronic cigarettes is illegal, in some countries as to electronic cigarettes must conform to the drug standard as a smoking cessation drugs sale. It needs to be stated that e-cigarettes have no efficacy in purification of lung, and the discussion about e-cigarette can clear lung poison is false and illegal propaganda.Chinese name: e-cigaretteElectronic cigaretteNickname: e-cigarette, electronic atomizerMain ingredients: plant extract, water, edible spicesPreservatives: noMain function: quit smoking and replace cigarettesSuitable crowd: people who have quit smoking, long-term smokers who feel bad and seek alternatives to cigarettesSide effects: the amount of nicotine in some e-cigarettes is fluctuating and may be inhaled as a lethal dose of nicotine. Some e-cigarettes are tested for toxic substances that contain nicotine.Storage: place in a cool, dry placeFunction: assist in quitting smoking and replacing cigarettesdirectoryA brief historyThe structureThe related contentSelection methodMethod of userestrictionsanA brief historyThe structureThe related contentSelection methodMethod of userestrictionsanEdit this sectionA brief historyGeneration electronic cigaretteThe original electronic cigarette is at the request of abroad, because there are a lot of foreign laws and regulations prohibit smoking in public places, and people generally high standard of living abroad, the wealthy, more strict in quality of life. So, originally designed for export of foreign trade. There were some brands at home, but they were very expensive. Almost no domestic sales, all exports. So many people don't know. But with the advent of the financial crisis, many export products have been sold out and prices have come down slowly.The design of a generation of e-cigarettes is completely modeled on the shape of ordinary real smoke, the smoke is yellow and the body is white. This generation of e-cigarettes has been popular for a few years because it is similar to real smoke andis accepted by customers in the first place. However, as people more and more on the use of the first generation of electronic cigarettes, especially foreign customers, in use process of slowly finds many of the shortcomings of the first generation of electronic cigarettes, mainly displays in the atomizer. The first generation of vaporized vaporizer is easy to burn, and when you change the smoke cartridge, it can easily hurt the tip of the atomizer. The cumulative effect of the cumulative effect will be completely worn down, resulting in no smoke from the atomizer.Secondary electronic smokeSecond generation electronic cigarettes than generation electronic cigarette is a bit long, is 9.25 mm in diameter, and the main characteristic is improved after the second generation of electronic cigarettes atomizer, atomizer outside with a protective cap, smoke flare is inserted into the atomizer inside,And a generation of e-cigarettes is an atomizer inserted into a smoke bomb, two exactly the opposite. The characteristics of the second generation of e-cigarettes are the combination of the smoke bomb and the atomizer, which is the most striking feature. The user needs to abandon the vaporizer every time he changes the smoke cartridge. Such a design can solve the problem of immaturity of the atomizer technology.Edit this sectionThe structureAlthough electronic cigarettes have style or brand, their basic structure is generally made up of three parts: battery rod, atomizer and smoke bomb.Schematic diagram of electronic cigarette structureThere are also two components: battery rods and vaporized smoke bombs, known as second-generation e-cigarettes.atomizerGenerally speaking, the smoke cartridge is the suction part, and some factories should glue the atomizer and smoke cartridge together to make a disposable atomizer. thisElectronic smoke structure diagramSample do advantage is that can greatly enhance the flavors of electronic cigarettes and smoke quantity, at the same time, the quality is more stable, because electronic cigarettes knows, atomizer is one of the most easily broken, traditional electronic cigarette is a separate atomizer, it broke a few days. This is also the fundamental reason why the e-cigarettes were questioned before. And if you keep using a single atomizer for a long time, the taste is very poor and the amount of smoke is very small. This directly affects the effect of quitting smoking. And professional liquid injection by the factory, to avoid his note to smoke too much or too less liquid back into his mouth or flow into the battery part corrosion problem of the circuit, the remaining oil smoke also more than generalsmoke bombs, sealed performance is good, so the use of his time than other smoke bombs. In this way he was more effective. The technology is currently owned by very few brands. The construction of the atomizer is a heating element, which makes the smoke and oil evaporate on the side of the battery, causing the smoke to evaporate, thus causing theinhaling to achieve the effect of "blowing smoke".rodThe inner structure of the smoke rod USES the same basic components: a lamp PCBA board, rechargeable battery, various electronic circuits.Most e-cigarettes use lithium-ion and secondary battery power components. Battery life depends on the type and size of the battery, the number of times and the operating environment. And many differenttypes of battery chargers are available, such as sockets for direct charging, car charging, and USB charger. Batteries are the biggest components of e-cigarettes.Some electronic cigarettes use an electronic airflow sensor to start the heating element, and an inhalation will make the battery circuit work. Manual sensing requires users to press a button and smoke. Pneumatic use is convenient, manual circuit is more stable than pneumatic, relatively speaking. It's better to smoke than air. Traditionally, electronic cigarettes have been activated by electronic means. This involves the use of pure hand mechanical switches andrelated circuits, heating components. Users can quickly find it's not very reliable, along with the development of the hardware and software, several automatic machinery manufacturing electronic cigarette manufacturers started to r&d, put an end to use manual wiring, welding or electronic, in order to achieve security and reliability. This is a trend, but once it's out, China can't make up its own market for making e-cigarettes in China at artificially low cost.Edit this sectionThe related contentQuit smoking principleThe most common use of nicotine replacement therapy in the world is the gradual reduction in the nicotine intake of smokers. Generally from high to low, gradual decrease. But even if the maximum concentration ofnicotine is only a third of that of a regular cigarette, it can avoid dependence on e-cigarettes.According to incomplete statistics, the electronic cigarette is nicotine replacement therapy now quit rate of the highest in all sortsof products, in addition to his used nicotine replacement therapy, hehas a big advantage, smoking is not to change my habitual action, as the saying goes, he will also be able to meet the mouth addiction to smoking. This is very important, because a large part of smokers, just can't get rid of this habit, just can't stop smoking.The working principle ofElectronic cigarettes through high-tech silicon control ofsmoke and air flow sensors output and working status of nicotine by atomization, the atomized particles into a solution containing the nicotine and essence, absorbed by the lungs, simulation of smoke at the same time. Without the tar and other harmful components of cigarettes, there will be no second-hand smoke or smoke in the enclosed space; Traditional cigarettes are lit by tobacco or tobacco, and harm thehealth of both smokers and non-smokers.Inhale, formed in sensor high-speed airflow, air flow sensors'people breathe in mouth, triggering air sensing switch, make the airflow sensor switch, products began to enter the working state. Thecentral processing unit controls the execution unit through calculation and measurement. The atomizer is controlled by the central control unit and is atomized according to the degree of oral suction. Atomizer iscomposed of high frequency oscillation circuit and the heating wire, in the atomizer, high purity electronic cigarettes liquid after superfine atomizing pump pressurized into the spray chamber, the high frequency of ultrasonic vibration on the critical atomized into droplets are about0.5 1.5 um, combined with inhalation of air dispersion into the form of aerosol, and simulation of the flue gas steam fog, look like smoke, is actually the fog. The critical atomization condition is to reduce the surface tension of the liquid to the most atomizing degree by heating, and simulate the temperature of ordinary flue gas (50-60 degree Celsius). At the same time, the green indicator light on the front of the e-cigarette lights up, simulating the cigarette flame, indicating that the e-cigarette is in the working state. When the inhalation is stopped, the air flow in the sensor disappears, the flow sensorswitches off, the circuit board IC processor stops working, the atomizer stops working, and the green indicator of the electronic cigarette end is extinguished.Scope of application1. Use the crowdChronic smoking and poor feeling.Long-term work in no-smoking places and smoking habit.There is a willing to quit.2. Applicable placesIt can be used in various smoking areas such as trains, theatres, hospitals and libraries.It can be used to prevent fire and fire units, such as gas stations and forest farms.3. Minors under 18 years of age are prohibited from using electronic cigarettes.Edit this sectionSelection method1. Quantity of smokeThe whole electronic smoke structure design, air inlet, air passage. Good e-cigarette design can guarantee a large amount of smoke, and then guarantee the stability of smoke.2. AtomizerThe function of the atomizer is the atomization, which is the core component of e-cigarette.A good electronic cigarettes, there must be a good atomizer, outstanding atomizer has the fever silk coarse, outside has the characteristic of steel ring protection, average width is about 5 mm in atomizer can guarantee good out of the smoke.Third, the batteryThe battery is connected to the atomizer, and liquid atomization requires a lot of energy, so the length of the battery life is the standard to measure whether an electronic cigarette is good. The link location of battery and atomizer with material is also key, every time when charging the place to turn, if the material is bad will soon appear wear Resulting in poor contact electronic smoke to stop working.Batteries that fuse with gold-plated technology tend to last longer than normal.Four, appearanceGood product, its appearance is relaxed, the design is rigorous, the work is exquisite, can give a person a kind of joyful feeling, help successful quit smoking.Five, the tasteThe current flavor is mostly marlboro, originally for the smoke. Taste is the defect of e-cigarette, but now it is more and more important in these years. Taste is also closer to real smoke, such as Chinese and licorice flavors are closer to real smoke. And peppermint and roasted tobacco and fruit flavors are preferred.Vi. Qualification certificationThere are many fake and inferior products on the market today, and the price is between tens and 100 yuan. These products have greatquality problems and health problems. Therefore, when purchasing e-cigarette products, it is necessary to see the relevant qualification and certification, and do not purchase fake and inferior products because of the low price.Edit this sectionMethod of useThe assembly wayElectronic smoke assembly anatomyPull out the smoke cartridge connected with the atomizer, replace it with a new smoke cartridge, and then connect it to the atomizer and smoke cartridge. Then you can enjoy the e-cigarette.Note: after the smoke of e-cigarette is opened, it is best to use it within three days.When the smoke drop is found, the smoke cartridge is used up, please change into a new smoke bomb.Use skills1. Be careful not to suck too hard when using, too hard to smoke. The smoke is sucked directly into your mouth because it is too hard to absorb, and it is not atomized by the atomizer. So it's more smoke and smoke.2. When smoking, please pay attention to take a long time to take a long breath, because the smoke in the smoke can be completely atomized by the inhaler for a long time, resulting in more smoke.3. Pay attention to the use of perspective, to keep up a cigarette holder, smoke bar downward-sloping, if smoking cigarette holder when rod up down, smoke liquid by gravity will naturally flowing downwards into your mouth.4. When the smoke comes into your mouth, take it down and take it apart, and wipe off the excess water from the cigarette's mouth and the atomizer before you use it.5. To keep the battery in sufficient power, the lack of electricity can also cause the smoke to be absorbed into the mouth without being fully atomized.Matters needing attention1. After the first or no smoke cartridge is placed for a period of time, you must first load the new smoke bomb and wait for a few minutes for the smoke to infiltrate. In the case of smokeless liquid, the use of electronic cigarette can easily damage the atomizer.2. A normal cigarette can absorb about 15 mouths.It is recommended that the user smoke the e-cigarette 14-16 for half an hour and then inhale.3. Lithium battery charging time 1.5-2 hours.The picture before the e-cigarette4. Direct inhalation of smoke from smoke cartridge is prohibited. Excessive amount of smoke can be directly exposed to the oral cavity, which can stimulate the mucous membrane of the mouth.Please put the e-cigarettes and smoke cartridge in the place where the children are not easy to contact.6. The decrease in the amount of electronic smoke and the lack of basic smoke indicate that the nicotine solution has been exhausted and new smoke cartridge should be replaced.Edit this sectionrestrictionsBecause electronic cigarette technology is relatively new, as wellas with the tobacco legal and some links of the medicine policy, so at present in many countries, legislation and public health survey about electronic cigarette is not settled yet.It is illegal to sell electronic cigarettes containing nicotine in Australia.In Austria, electronic cigarettes are believed to be medical devices, as well as medical products with nicotine tubes. Therefore, before legitimate sales, electronic cigarettes must have the CE (European commission) logo and the nicotine cartridge is registered as a medical product.In Brazil, electronic cigarette sales, imports or any form of advertising are prohibited. The Brazilian health watchdog (Anvisa) found that the current health and safety assessment of electronic cigarettes was still unsatisfactory, so that electronic cigarettes could not be commercially approved.In the Czech republic, electronic cigarette use and advertising are currently unrestricted.Electronic cigarettes are legal in Denmark, but the nicotine tube is currently under a temporary ban because of a review by Danish health authorities.In Canada, the use of electronic cigarettes is under reviewbecause of a smoking ban in public places. Canada has not yet approved market licenses for any electronic cigarette products.It is illegal to sell or buy a nicotine cartridge through theInternet in Finland, but it is not illegal to buy the nicotine cartridge used for personal use from overseas sources.It is illegal to own or sell electronic cigarettes in Hong Kong.In the Netherlands, electronic cigarettes are permitted, but electronic cigarette advertising is banned before the European Union is established.In New Zealand, the ministry of health says the nicotine canister is required to comply with the medical bill unless it is marketed as a registered drug.In panama, distribution and sales of electronic cigarettes have been banned since September 2009.In South Africa, the use of electronic cigarettes is currently unrestricted.In tajikistan, the use of electronic cigarettes is currently unrestricted.In Britain, the use of electronic cigarettes is currently unrestricted.In the United States, the food and drug administrationconsiders electronic cigarettes to be a nicotine release device that needs FDA approval. The agency is currently investigating electronic smoking devices and has prevented some electronic cigarette products from importing to the United States.Legal disputes, Virginia attorney general health in sinai, Leon (Ken Cuccinelli), because they make electronic cigarette is not to violate the Virginia indoor public places the decision of the smoking ban, but has been support and criticism from health groups different camps.The ruling means that virginians are free to use electroniccigarettes in restaurants and other places where smoking is banned.Science and health committee in the United States a message on the website of references, the Washington post reported in sinai, judgement, electronic cigarette devices from the hot water vapor does notconstitute a "usually people understand" smoke. Report quoted a spokesman of the American cancer society, the ruling "for us toestablish a smoke-free workplace and promote a healthy environment and are trying to do everything" in Virginia is backwards.But Elizabeth whelan, founder of the American council on science and health, has a different view of the situation. "The American cancer society is basically saying, 'stick with the real thing -- cigarettes,'" she said. She praised him for making such a ruling. She added: "the person who has the scientific knowledge is in contact with him and explains the actual situation to him."Disadvantages 1. E-cigarettes are not real tobacco because theydon't burn. The taste can never be the same as cigarettes.2. The e-cigarette industry is currently in a chaotic market, especially the taobao market, which is full of fake products. Even someof the best selling products, the corresponding qualifications of the manufacturers are not up to standard.3. The lack of effective supervision of e-cigarettes has led to an uncertain future.4. There is also obvious exaggeration of electronic cigarettes. For example, many people advertise that e-cigarettes have the effect of clearing lung poison. This is all illegal propaganda, electronic cigarette is not even medicine, not to be clear lung poison at all. And science has shown that e-cigarettes don't have any function of clearing the lungs. E-cigarettes now only have the effect of replacing cigarettes and helping to stop smoking.。

电子烟中重金属含量的检测与限制标准研究

电子烟中重金属含量的检测与限制标准研究一、背景介绍近年来，电子烟作为一种新型的烟草类产品，已经在全球范围内得到流行。

与传统烟草不同，电子烟使用电池加热电子烟油来产生烟雾，但是其烟油中也含有一定量的化学物质，其中包括了重金属元素。

重金属元素是指密度大于5克/厘米立方的金属元素，如铅、汞、镉等，这些元素会对人体健康产生潜在的风险。

因此，了解电子烟中重金属元素的含量以及制定相应的限制标准是非常重要和必要的。

二、检测方法目前，有多种方法可以用于电子烟中重金属元素的检测。

其中，最为常用的方法是原子吸收光谱法（AA）和质谱法（MS）。

这些方法的基本原理都是将样品中的重金属元素吸收或者分离出来，然后测定其光谱或质谱特性以得到重金属元素的含量。

此外，还有其他方法如电离质谱法（ICP-MS）和荧光法（FL）等。

这些方法可以被用来对电子烟中含有的重金属元素进行准确的测定，为制定限制标准提供重要的依据。

三、重金属元素含量的研究多项研究表明，电子烟中的烟油可以含有铅、镉、铬、汞和锡等多种重金属元素，其中含铅量最高。

一项对20种电子烟品牌的研究表明，其中19种烟油中含有铅，平均含量为0.36微克/升。

同时，还有部分烟油中检测到了其他重金属元素，如镉和铬等。

除了单一元素的研究，也有研究对电子烟烟油中多种元素的含量进行了研究。

例如，一项针对20种电子烟烟油的研究表明，其中15种烟油中含有镉、铅和铜等多种元素，且有些元素的含量超过了生活饮用水中允许的标准。

这些研究结果表明，电子烟中的烟油确实含有重金属元素，并且有些元素的含量可能超标。

但是，需要指出的是，不同品牌和型号的电子烟烟油可能含有不同的重金属元素种类和含量，因此需要进行更为全面和具体的研究。

四、限制标准的制定根据现有的研究结果，可以制定电子烟中重金属元素的限制标准。

对于含铅量，可以参考饮用水的含铅标准，即不得高于0.01毫克/升。

同时，对于其他重金属元素，也可以参考相关的标准进行制定。

e-cigarettes电子香烟编译

电子烟依然存在二手烟最开始，人们对电子烟十分好奇，声称其响应了无烟政策——由于电子烟不会产生有害烟雾。

现在，已经有许多电子烟工厂应运而生。

但是，电子烟是否真的安全？现在的问题在于电子烟是否比传统香烟危害更少。

电子烟是电子产品，有着与传统香烟一样的外观，也像香烟一样能吸出烟。

医学专家称，吸电子烟是为了让人们戒烟。

但由于比一般香烟的口味要多出很多，甚至还有水果味的。

那些不抽烟的人也开始喜欢抽烟了。

而且吸电子烟不受约束，相对于传统香烟一年的花费，电子烟的花费少了将近一半。

专家称，电子烟也许比传统香烟安全，但这并不意味着绝对安全。

吸电子烟时所产生的不是烟，而直接是雾气，直接地，更快速地进入肺部，心脏，甚至大脑中。

一旦成瘾，癌症发病几率，先天畸型，发育障碍几率便会增加。

2006年《妇产科学杂志》研究表明，嚼尼古丁口香糖的孕妇比不嚼的孕妇生产风险更高。

目前，电子烟的制造还不甚完善，对身体的危害还处于未知状态。

上个月《成瘾行为》研究表明多数利用电子烟想要戒烟的人，最终要么吸电子烟成瘾，要么又开始抽烟。

科学家发现电子烟对戒烟并没有多大帮助。

因为吸烟着普遍都有这种心理矛盾——想要利用抽烟来缓解自己的矛盾的心理。

一些科学家认为，电子烟或许能帮一些人戒烟，但是从广义上来讲，吸电子烟依然有尼古丁，同样没有达到香烟制造商所说的制造更干净，更环保，更健康的社会。

那么电子烟里面究竟含哪些成分呢？现在还不清楚。

由于电子烟缺乏有系统的临床实验数据支持，也没有系统的管理条例，这项新技术还不能有效的管理。

新西兰号召规范生产和安全销售电子烟，美国食品和药物管理局计划根据《烟草控制法》规范推广烟制品。

E-Cigarettes Just More Smoke and Mirrors, Doctors Say At first, electronic cigarettes were a novelty —something a braggart in a bar might puff to challenge the established no-smoking policy, marveling bystanders with the fact that the smoke released from the device was merely harmless vapor.Now, e-cigarettes are poised to be a billion-dollar industry, claimed as the solution to bring in smokers from out of the cold, both figuratively and literally, as e-cigarettes promise to lift the stigma of smoking and are increasingly permitted at indoor facilities where smoking is banned.So, are e-cigarettes safe? Well, they're not great for you, doctors say. What's being debated is the degree to which they are less dangerous than traditional cigarettes. 1940 revisitedE-cigarettes are battery-powered devices, often shaped like traditional cigarettes, with a heating element that vaporizes a liquid nicotine solution, which must be replaced every few hundred puffs. Nicotine is inhaled into the lungs, and a largely odorless water vapor comes out of the device. Puffing an e-cigarette is called vaping.Yet the industry's duplicity is clear to medical experts: E-cigarettes are marketed to smokers as a means to wean them off of tobacco (although studies show they don't help much); yet the same devices, some with fruity flavors, are marketed to youngpeople who don't smoke, which could get them hooked.Hooked? Yes, e-cigarettes are a nicotine-delivery system, highly addictive and ultimately harmful because of their nicotine.Cancer and respiratory experts see the same ploy being played out today with e-cigarettes as was done in the 1940s with cigarettes, when America started smoking en masse. They often are distributed for free and pitched by celebrities and even doctors as cool, liberating and safe.In an ad for a product called blu eCigs, celebrity Jenny McCarthy, infamous for encouraging parents not to vaccinate their children, encourages young adults to vape, enlisting words such as "freedom" and the promise of sex. In another ad, for V2 Cigs, a medical doctor named Matthew Huebner — who is presented without affiliation but is associated with a Cleveland Clinic facility in Weston, Fla. — implies that vaping is as harmless as boiling water.As for the notion of e-cigs as liberating, the cost of a year's worth of e-cigarette nicotine cartridges is about $600, compared with $1,000 yearly for a half-pack a day of regular cigarettes.As for whether they're safe, it's a matter of comparing the advantages of one addiction over another.E-cigarettes not a patchOne would think that vaping has to be safer than smoking real cigarettes. Experts say they are probably safer, but safer doesn't mean safe."Cigarettes have their risk profile," said Dr. Frank Leone, a pulmonary expert at the University of Pennsylvania Medical Center in Philadelphia. And just about everyone who breathes understands the risks: circulatory disease and myriad cancers, for starters. "E-cigarettes might be better off compared to that profile. But that doesn't mean they don't have their own risk profile."A top concern is the nicotine delivery rate, Leone said. With nicotine patches and gum, the nicotine delivery is regulated, with small amounts of nicotine released slowly into the bloodstream. But with traditional cigarettes and now e-cigarettes, heat creates a freebase form of nicotine that is more addictive — or what smokers would call more satisfying. The nicotine goes right into the lungs, where it is quickly channeled into the heart and then pumped into the brain.Once addicted, the body will crave nicotine. And although nicotine isn't the most dangerous toxin in tobacco's arsenal, this chemical nevertheless is a cancer-promoting agent, and is associated with birth defects and developmental disorders.A study published in 2006 in the journal Obstetrics and Gynecology, for example, found that women who chewed nicotine gum during pregnancy had a higher risk of birth defects compared to other nonsmokers.Great unknownsThis great unknown of possible negative health effects, along with the lack ofregulation of e-cigarettes, scares experts like Leone. The products come bereft of health warnings. How many pregnant women will vape following McCarthy's promotion?As for their merits in smoking cessation, e-cigarettes don't appear very helpful. A study published last month in the journal Addictive Behaviors found that most smokers who used them while they tried to quit either became hooked on vaping, or reverted back to smoking cigarettes. A study published Nov. 16 in the journal The Lancet found no statistically significant difference in the merits of the e-cigarette over the nicotine patch in terms of helping people quit.Leone said that e-cigarettes might not help people quit smoking because the device keeps addicts in a state of ambivalence —the illusion of doing something positive to mitigate the guilt that comes from smoking, but all the while maintaining the ritual of smoking.The Jenny McCarthy blu eCigs ad hints at this notion, with such phrases as "smarter alternative to cigarettes," "without the guilt" and "now that I switched (I)feel better about myself."Editors of The Lancet called promotion of e-cigarettes "a moral quandary" because of this potential to replace harmful cigarettes with something slightly less harmful yet just as addictive. Other researchers agree that e-cigarettes might help some people quit, but at a population level, converting millions of smokers into vapers still addicted to nicotine might not lead to the cleaner, greener, healthier world implied by e-cigarette manufacturers.And then there's the issue of not knowing what's in the e-cigarette nicotine cartridge. "It's an amazing thing to watch a new product like that just kind of appear; there's no quality control," said Dr. Richard Hurt, director of the Mayo Clinic's Nicotine Dependence Center in Rochester, Minn. "Many of them are manufactured in China under no control conditions, so the story is yet to be completely told."The authors of The Lancet study, all based in New Zealand, called for countries to regulate the manufacturing and sale of e-cigarettes. The U.S. Food and Drug Administration, which does not approve any e-cigarettes for therapeutic purpose, said it plans to propose a regulation to extend the definition of "tobacco product" under the Tobacco Control Act to gain more authority to regulate products such as e-cigarettes.电子香烟：烟雾重重迷雾层层电子香烟最初只是酒吧新宠，如今已经发展成数十亿美元的产业，然而，电子香烟真的安全吗？医生们说，其危害与传统香烟相比，只是程度上的差别。

GB41700-2022《电子烟》国家标准发布，将于10月1日正式实施

GB41700-2022《电子烟》国家标准发布，将于10月1日正式实施解读《电子烟》国家标准将于今年10月1日正式实施。

问：《电子烟》国家标准的制定背景和主要内容是什么？答：2021年11月，国务院印发了《关于修改<中华人民共和国烟草专卖法实施条例>的决定》（国务院令第750号），增加第六十五条，“电子烟等新型烟草制品参照本条例卷烟的有关规定执行”。

2022年3月11日，国家烟草专卖局制定发布了《电子烟管理办法》，将于5月1日正式施行，办法提出“电子烟产品应当符合电子烟强制性国家标准”。

因此，制定《电子烟》强制性标准是落实上述法律法规的重要手段，也是建立电子烟监管体系的重要技术支撑。

2022年4月8日，市场监管总局（标准委）发布了GB 41700-2022《电子烟》强制性国家标准。

该标准由市场监管总局会同国家烟草专卖局，组织全国烟草标准化技术委员会和相关技术机构制定。

标准内容主要包括：一是明确了电子烟、雾化物等相关术语、定义；二是对电子烟设计和原材料的选用等提出原则要求；三是对电子烟烟具、雾化物和释放物分别提出明确的技术要求，并给出了配套的试验方法；四是对电子烟产品标志及说明书进行了规定。

问：《电子烟》国家标准技术内容的突出特点是什么？答：《电子烟管理办法》明确禁止销售除烟草口味外的调味电子烟和可自行添加雾化物的电子烟。

基于《电子烟管理办法》的监管要求，并接轨国际监管趋势，借鉴国际监管经验，《电子烟》国家标准提出了科学适用的技术内容，其突出特点体现在：第一，规定电子烟是“用于产生气溶胶供人抽吸等的电子传送系统”，将不含烟碱的电子烟纳入电子烟定义范围。

第二，鉴于水果、食品、饮料等调味电子烟和无烟碱电子烟对未成年人具有较强的吸引力，容易诱导未成年人吸食，标准明确规定不应使产品特征风味呈现除烟草外的其他风味，并明确要求“雾化物应含有烟碱”，即不含烟碱的电子烟产品不得进入市场销售。

第三，标准依据添加剂的使用原则，经过充分安全风险评估论证、实验验证并广泛征求意见后，明确列出允许使用的101种添加剂，纳入添加剂“白名单”。

电子烟烟雾质量浓度表征及影响因素

电子烟烟雾质量浓度表征及影响因素李寿波;朱东来;韩熠;巩效伟;张霞;陈永宽;吴俊;洪鎏;李廷华【摘要】为评价电子烟烟雾质量浓度并探究其影响因素,基于气溶胶光学特性建立了利用透光率定量表征烟雾质量浓度的方法,采用开发的烟雾质量浓度测试系统考察了不同抽吸参数、烟液溶剂、工作电压和电阻对烟雾质量浓度的影响.结果表明:①当抽吸容量一定时,在较短抽吸间隔条件下,电子烟烟雾质量浓度较大.②使用甘油和1,2-丙二醇混合溶剂时,电子烟烟雾质量浓度大于使用单一溶剂.③在相同的抽吸条件下,电子烟输出功率与烟雾质量浓度正相关.该表征方法和测试系统合理、有效,适用于电子烟烟雾质量浓度的实时、定量分析.%In order to evaluate the vapor mass concentration of e-cigarette aerosol and to investigate its influencing factors,a method for quantitatively characterizing the mass concentration of e-cigarette aerosol via optical transmittance was established. The effects of machine puffing parameters,solvent types and concentrations in e-liquid,coil working voltage and coil resistance of e-cigarette on the vapor mass concentration were investigated by adopting the developed test system. The results showed that:1)Under constant puffing volume,the vapor mass concentration was larger at a shorter puffing interval. 2)When the mixture of glycerol and 1,2-propylene glycol was used as the solvent of e-liquid,the mass concentration of e-cigarette aerosol was higher than that of a single solvent. 3)Under the same puffing condition,the output power of e-cigarette coil positively correlated to the mass concentration of the aerosol produced. This characterization method and the developed test system are reasonable,effective,and suitable forreal-time quantitative analysis of the mass concentration of e-cigarette aerosol.【期刊名称】《烟草科技》【年(卷),期】2018(051)004【总页数】6页(P35-40)【关键词】电子烟;烟雾质量浓度;气溶胶;光学特性;透光率【作者】李寿波;朱东来;韩熠;巩效伟;张霞;陈永宽;吴俊;洪鎏;李廷华【作者单位】云南中烟工业有限责任公司技术中心,昆明市五华区红锦路367号650000;云南中烟工业有限责任公司技术中心,昆明市五华区红锦路367号650000;云南中烟工业有限责任公司技术中心,昆明市五华区红锦路367号650000;云南中烟工业有限责任公司技术中心,昆明市五华区红锦路367号650000;云南中烟工业有限责任公司技术中心,昆明市五华区红锦路367号650000;云南中烟工业有限责任公司技术中心,昆明市五华区红锦路367号650000;云南中烟工业有限责任公司技术中心,昆明市五华区红锦路367号650000;云南中烟工业有限责任公司技术中心,昆明市五华区红锦路367号650000;云南中烟工业有限责任公司技术中心,昆明市五华区红锦路367号650000【正文语种】中文【中图分类】TS411.2电子烟是一类具有发展潜力的低风险新型烟草制品，通过电加热方式雾化烟液产生气溶胶以供用户享用，因其在生理感受、心理感知和吸食方式等方面较为接近传统卷烟，得到了广大消费者的青睐［1-6］。
