什么是“化学”呢?这个问题一直伴随着我到初中二年级,才让我悄悄地从朦胧中解开。

在千变万化的物质世界里,不仅存在着形形色色的物质,而且物质还在不断变化着;化学就是要研究物质及其变化,它不仅要研究自然界已经存在物质及其变化,还要根据需要研究和创造自然界不存在的新物质。

在学习《化学》的过程中,我从中遇到了许多有趣的问题,如:水、氧气、二氧化碳等的.元素组成表示方法,怎样写化学方程式等;也知道化学元素有100多种,也明白了什么是物理变化、什么是化学变化;在实验课上,小苏打与醋会产生二氧化碳,还会生出许多白沫......
《三国演义》中诸葛亮第4次释放孟获时孟获去秃龙洞求助,秃龙大王借了哑泉、灭泉、黑泉、柔泉四个毒泉消灭蜀军。

哑泉水喝了会哑巴,几天后便死了;灭泉水滚烫,如果用这水洗澡,就会骨肉尽脱;黑泉的水看似清澈,溅到身上就会浑身乌黑而死;人喝了柔泉的水就会浑身冰凉而死。

天气炎热,人马争先恐后的喝哑泉里的水,结果个个都说不出话来,生命危在旦夕。

诸葛亮也没有办法。

幸好一位老叟指点喝了万安溪的安乐泉水才转危为安。

你知道这是为什么吗?原来是铜盐在作怪。

人只要喝了含有铜盐的水就会吐字不清,因为它可以麻痹人的声带,最后因痉挛而死,那为何喝了晚安溪河里的水可以转危为安呢?因为该水中含有较多的碱,碱和铜盐

人类滥用化学品带来的灾难作文素材

人类滥用化学品带来的灾难作文素材英文回答:The abuse of chemicals by humans has resulted in numerous disasters and catastrophic consequences. One of the most significant examples is the pollution of water bodies and ecosystems due to the excessive use of pesticides and fertilizers in agriculture. These chemicals, when washed away by rainwater or irrigation, can contaminate rivers, lakes, and groundwater sources, leading to the destruction of aquatic life and the disruption of entire ecosystems.Another devastating consequence of chemical abuse is the depletion of the ozone layer. Substances such as chlorofluorocarbons (CFCs) used in refrigerants and aerosol propellants have been found to contribute to the thinning of the ozone layer, which protects the Earth from harmful ultraviolet (UV) radiation. The thinning of the ozone layer has resulted in increased cases of skin cancer, cataracts,and other health issues in humans and animals.Moreover, the indiscriminate use of chemical pollutants, such as heavy metals and industrial waste, has led tosevere air pollution. Emissions from factories and vehicles release harmful substances like sulfur dioxide, nitrogen oxides, and particulate matter into the atmosphere, causing respiratory problems, cardiovascular diseases, and even premature death. The accumulation of these pollutants inthe atmosphere also contributes to climate change andglobal warming.Furthermore, the improper disposal of chemical waste poses a significant threat to both human health and the environment. Many hazardous chemicals, including toxic solvents, heavy metals, and radioactive materials, are improperly disposed of in landfills or dumped into rivers and oceans. This not only contaminates the soil and water but also poses long-term risks to human populations livingin close proximity to these sites.中文回答:人类滥用化学品带来的灾难是多方面的。

比如说一些污染环境的化学物质排放,像酸雨的形成就和大气中的化学污染有关。

但只要我们好好地管理和控制,化学就能继续为我们人类的美好生活发光发热。

写苯的危害作文

写苯的危害作文

写苯的危害作文示例回答如下1:English:Title: The dangers of benzeneIn our daily lives, there is a substance that is little known, but it is everywhere, quietly affecting our health. The substance is benzene, a common organic compound widely used in chemicals, medicine, pesticides and everyday products. However, the harm of benzene cannot be ignored, and its negative effects on the environment and human health deserve our deep thought.First, let's look at the basic properties of benzene. Benzene is a colorless transparent liquid, with a special aroma, volatile, easily soluble in organic solvents. Because of these characteristics, benzene is widely used in industry, such as plastics, synthetic fibers, rubber, detergent, paint, ink and other production can not be inseparable from its figure. However, it is these widespread applications that make benzene one of the important sources of environmental pollution.Benzene in the environment is mainly released into the atmosphere through industrial emissions and the burning of petroleum products. With the rapid development of industry and the surge in the number of cars, benzene emissions are also rising, causing a serious impact on the environment. Benzene can form photochemical smog in the air and participate in the formation of the ozone layer on the surface, which exacerbates the problem of urban photochemical pollution. In addition, benzene may enter water bodies through industrial wastewater and municipal sewage, causing damage to aquatic ecosystems.For the human body, benzene is a toxic substance, long-term contact or inhalation of high concentrations of benzene vapor will cause serious threats to human health. The main harm of benzene includes the following aspects: First, the harm of the hematopoietic system, long-term exposure to benzene can lead to leukopenia, leukemia and other blood diseases; Second, the impact of the nervous system, inhalation of high concentrations of benzene vapor can lead to dizziness, headache, nausea, lethargy and other symptoms, and even coma in severe cases; Third, the damage of the immune system, benzene can reduce the body's immunity, increase the risk of infection; Fourth, the impact of the reproductive system, benzene has a certain toxicity to germ cells, may affect fertility.What's more, benzene is carcinogenic. The International Agency for Research on Cancer has classified benzene as a human carcinogen. Workers with long-termexposure to benzene have a much higher risk of developing leukemia and other malignancies than the general population. Therefore, the contact control and protection measures for benzene are particularly important.What should we do about the dangers of benzene? First of all, the government and relevant departments should strengthen the supervision of benzene-containing products, formulate strict emission standards, and reduce industrial emissions of benzene. Secondly, enterprises should adopt cleaner production technology to reduce the amount of benzene used and improve the recycling rate. Third, consumers should improve their awareness of self-protection, choose low-benzene or benzene-free daily products, and reduce exposure to benzene. Finally, for professionals with benzene in the working environment, necessary personal protective equipment should be provided, regular health checks should be carried out, and health problems should be found and dealt with in a timely manner.Benzene is a kind of universal chemical substance, its harm can not be ignored. We should reduce the use and emission of benzene from the source, strengthen environmental protection and personal protection, in order to protect human health and the sustainable development of the environment. Only in this way can we find health and peace in the shadow of benzene.中文:标题:苯的危害在我们的日常生活中,有一种物质虽然鲜为人知,但它却无处不在,悄无声息地影响着我们的健康。

化学污染与人体健康化学污染——空气污染随着社会的发展,人类探求到的知识越来越更深入。

当然化学也在一步步的走进人们的生活,但我们都知道化学它是一柄双刃剑,不只对生活也对环境造成了一定影响。

先看最贴近人们身边的也就是新房装修了。

每个人买了新房都想装修得漂漂亮亮,这样住进去后会很舒适,而装修过房子的人都知道,房子装修后不可以立即住进去,而是要过挺长一段时间才可以搬进去,那是因为装修所使用的油漆等材料都是通过化学成分的混合反应制取而成的,其中最重要的污染物便是人们耳熟能详的甲醛、苯等。

甲醛具有强烈气味,吸入高浓度甲醛后,会出现呼吸道的严重刺激。

而我们的皮肤直接接触甲醛,会引起皮炎。

经常吸入少量甲醛,会引起慢性中毒。

另外苯是一种无色、具有特殊芳香气味的液体。

长期吸入苯会导致再生障碍性贫血。

逢年过节时,大街小巷都有燃放烟花爆竹的,原本是为节日增加愉悦的气氛,却不想在人们娱乐的同时它释放了大量的二氧化硫等有毒气体。

而二氧化硫是近年来重要的大气污染物之一,塔克在硫磺燃烧的条件下生成,无色、有刺激性的气味,溶解于水中便形成了所谓的亚硝酸进而形成了酸雨。

我们知道酸雨具有严重危害,不只直接毁坏农作物、森林、草原,纵使土壤、湖泊酸化,还加速建筑物、桥梁、工业设备、运输工具及电信电缆的腐蚀。

此外,二氧化硫易被湿润的粘膜表面吸收而生成亚硝酸、硫酸。

这对人们的眼及呼吸道粘膜有及强烈的刺激作用,因而会引起呼吸道的疾病,严重者可直接致人死亡。

由此可见,化学不但导致空气污染恶化,还影响着人们的日常生活。

以上种种可见的化学物质对空气污染的严重性和对人体的危害。

证明我们所生存的空间没有一样离开了化学,在化学为生活带来方便的同时,也在无形中污染着人赖以生存的空气。

所以,正确的运用化学去解决我们身边的问题,减少对空气的污染,才是更应该继续探求的道路。

空气污染还包括大气的生物性污染和大气的放射性污染。

大气的生物性污染物主要有病原菌、霉菌孢子和花粉。

病原菌能使人患肺结核等传染病,霉菌孢子和花粉能使一些人产生过敏反应。

大气的放射性污染物,主要原子能工业的放射性废物和医用射线源等,这些污染物容易使人患皮肤癌和白血病等。

河流、湖泊等水体一旦污染后,对人体健康会造成严重的危害。

这主要表现在三个方面。

第一,引用污染水和食用污水中的生物,会使人中毒,甚至死亡。

如:年,日本熊本县的水俣湾地区出现一些病因不明的患者。

患者拥有痉挛、麻痹、运动失调、语言和听力发生障碍等症状,最后因无法治疗而痛苦死去,人们称这种怪病为水俣病。

科学家们后来研究发现了这种病是由当地含汞的工业废水造成的。

化学污染——固体废弃物污染化学污染——噪声污染化学污染——环境污染环境污染往往具有使人或哺乳动物致癌、致突变和致畸的作用,统称三致作用。

三致作用的危害,一般需要经过比较长的时间才显露出来,有些危害甚至影响到下一代。

①致癌作用:指导致人或哺乳动物患癌症的作用。

早在年,英国医生波特就发现清扫烟囱的工人易患阴囊癌,他认为患阴囊癌与经常接触煤烟灰有关。

年,日本科学家通过实验证实,煤焦油可以诱发皮肤癌。

污染物中能够诱发人或哺乳动物患癌症的物质叫做致癌物。

致癌物可以分为化学性致癌物(如亚硝酸盐、石棉和生产蚊香用的双氯甲醚)、物理性致癌物(如镭的核聚变物)和生物性致癌物(如黄曲霉毒素)三类。

②致突变作用:指导致人或哺乳动物发生基因突变、染色体结构变异或染色体数目变异的作用。

人或哺乳动物的生殖细胞如果发生突变,可以影响妊娠过程,导致不孕或胚胎早期死亡等。

人或哺乳动物的体细胞如果发生突变,可以导致癌症的发生。

常见的致突变物有亚硝胺类、甲醛、苯和敌敌畏等。

③致畸作用:指作用于妊娠母体,干扰胚胎的正常发育,导致新生儿或幼小哺乳动物先天性畸形的作用。

世纪年代初,西欧和日本出现了一些畸形新生儿。

科学家们经过研究发现,原来孕妇在怀孕后的天~天内,服用了一种叫做反应停的镇静药,这种药具有致畸作用。

目前已经确认的致畸物有甲基汞和某些病毒等。

参考文献:《初中化学教师教学用书》《环境报》空气污染主要指的是大气的化学性污染。

大气中化学性污染物的种类很多,对人体危害严重的更多达几十余种。

大气污染物主要分两大类:①气态污染物(如二氧化硫、硫化氢、一氧化碳、二氧化碳、二氧化氮、氨、氯气等)②颗粒态污染物(如烟、雾、粉尘)。

大气的污染源主要是三方面:①生活污染源:如家庭、商业服务部门等燃煤排放的烟尘和废气。

②交通污染源:如汽车、火车、飞机、船舶等排放的废气。

③工业污染源:如发电厂、水泥厂、氮肥厂、烧碱厂及其它各类化工厂排放的废气和粉尘。

(我国的大气污染属于煤炭性污染)。

大家最平常见到的如:新房的装修,部分地方有毒气体外泄,人们燃放烟花爆竹,工业生产的排放等等很多都对空气造成了污染。

社会上有人曾调查,我国每年由室内空气污染引起的死亡人数已达万,装修的空气污染也已被列入对公众危害最大的五种环境因素之一。

而我国每年新增白血病患者万—万人,其中约%是儿童,据一儿童医院血液科统计,所接诊的白血病患儿中,%家庭在半年之内曾进行房屋装修。

看来化学污染已经是不可避免的话题,它已深入我们的生活。

随着人们的生活水平不断提高,人们拥有自己的车。

开车的感觉挺好却不知汽车尾气所排放的也是化学污染空气的又一大实例。

在机动车内燃机中燃烧燃料产生的高温条件下,空气中的氮气往往也参与反应,从而产生了一氧化氮,一氧化氮(又易氧化生成的二氧化氮)是有刺激性气味的有毒气体,并且二氧化氮是形成光化学烟雾的主要因素之一,也是酸雨的来源之一,也是主要的大气污染物之一。

除此之外,尾气中还含有氮氧化合物,它和碳氢化物在一定气象条件下受太阳紫外线作用,产生一种具有刺激性浅蓝色的烟雾,称为光化学烟雾,这种物质也对人体造成危害。

然而,大部分人所不知道的是汽车尾气不仅仅对人产生危害,它对植物也有毒害的作用,尾气中的二次污染物臭氧、过氧乙酯基硝酸酯,可使植物叶片出现坏死病斑和枯斑,乙烯可影响植物的生长、开花与结果。

另外汽车尾气的排放对甜菜、菠菜、西红柿、烟草的毒害更为严重。

由此我想公路两侧的农作物之所以减产与汽车尾气的污染一定有关。

大气污染物中最厉害的污染物是烟尘和二氧化硫,此外,还有氮氧化物和一氧化碳等。

这些污染物主要通过呼吸道进入人体的体内,不经过肝脏的解毒作用,直接由血液运输到全身。

所以,大气的化学性污染对人体健康的危害是很大的。

这种危害基本可分为慢性中毒、急性中毒和致癌作用三种。

慢性中毒:在大气中化学性污染物的浓度一般比较低,对人体也就产生慢性毒害的作用。

科学研究表明,城市大气的化学性污染是慢性支气管炎、肺气肿和支气管哮喘等疾病的重要诱因。

急性中毒:在工厂大量排放有害气体,并且在无风、多雾时,大气中的化学污染物不易散开,因而就使人急性中毒。

如:年,日本四日市的三家石油化工企业,因为不断大量排放二氧化硫等化学性污染物,加上无风的天气,致使当地居民哮喘病急剧发生。

后来,当地的这种大气污染得到了相应的治理,哮喘病的发病率也随之降低了很多。

致癌作用:大气中化学性污染物中具有致癌作用的有多环芳烃类(像,-苯并芘)和含的化合物等,其中,-苯并芘引起肺癌的作用最强烈。

像燃烧的煤炭、行驶的汽车和香烟的烟雾中都含有很多的,-苯并芘。

大气中的化学性污染物还可以降落到水体和土壤中以及农作物上,被农作物吸收和富集后,进而危害人体健康。

化学污染——水污染汞转化成甲基汞后,富集在鱼、虾和贝类的体内,人们如果长期食用这些鱼、虾和贝类,甲基汞就会引起以脑细胞损伤为主的慢性甲基汞中毒。

孕妇体内的甲基汞,甚至会使患儿发育不良、智能低下和四肢变形等。

第二,被人畜粪便和生活垃圾污染了的水体,能引起病毒性肝炎、细菌性痢疾等传染病,以及血吸虫病等寄生虫疾病。

第三,一些具有致癌作用的化学物质,如砷()、铬()、苯胺等污染水体后,可在水体中的悬浮物、底泥和水生生物体内积蓄。

长期饮用这样的污水,容易诱发癌症。

固体废弃物是指人类在生产和生活中丢弃的固体物质,像采矿业的废石,工业的废渣,废弃的塑料制品,以及生活垃圾等。

我们应当认识到的是,固体废弃物只是在某一过程或某一方面没有使用价值,实际上往往可以作为另一生产过程的原料被利用,因此,固体废弃物有另一个名字叫放在错误地点的原料。

但是,这些放在错误地点的原料,往往含有多种对人体健康有害的物质,如果不及时加以利用,长期堆放,以至越积越多,就会污染生态环境,对人体健康也造成一定的危害。

噪声主要对人产生一定危害。

而这危害是多方面的:第一,损伤听力。

人们长期在强噪声中工作,听力就会下降,甚至造成噪声性的耳聋。

第二,干扰睡眠。

当人的睡眠受到噪声的干扰,就不能消除疲劳,还有会诱发胃肠溃疡和内分泌系统功能紊乱等疾病。

第三,影响心理健康。

噪声使人心情烦躁,不能集中精力学习或工作,并且容易引复体力。

第四,诱发多种疾病。

噪声会使人一直处在紧张状态下,致使心率加快、血压升高,甚至发生工伤或交通事故。

因此,我们应当采取多种措施,防治这种污染,使包括人类在内的所有生物都生活在安静美好的环境下。

环境污染包括很多内容,我们主要看环境污染对生物的影响及环境污染鱼三致作用。

面对这么多的严峻的污染问题,我们应积极行动起来,珍惜我们身边的一切,让我们生活在更好的社会环境中,这样我们的生活也会更加美好。
