[空气污染的危害]空气污染第一篇空气污染:空气污染环境作文大家都知道我们应该减少空气污染，但是很多人都只是嘴上说说，根本不去实践!你们知道空气污染的危害吗，你们知道如果不减少空气污染我们将要面临的是怎样的未来吗我的家乡——大连，是座美丽的城市。
听爸爸说，以前的大连是个环境优美，空气清新的城市，空气中到处弥漫着海洋的味道，夏季的雨后，经常能看到美丽的彩虹如七彩桥一般挂在天边。
我在家里看到过很多爸爸小时候的生活照片，在照片的背景中，我看到天空万里无云，马路上很少有各式各样的机动车，那时人们的交通工具主要就是靠公共汽车，环境确实比现在好多了。
现在家乡的车辆增多了，每天都有成千上万辆汽车行驶在马路上，这些汽车排放的尾气，不仅破坏了环境，同时也危害了人们的身体健康。
我听广播说，汽车排放出的尾气使我们的城市变暖了，而且这些气体悬浮在城市上空很难消散，汽车尾气中还有大量的一氧化碳和二氧化碳，这些气体都是对人体有伤害的，如果被人们吸到体内，就会引起肺部的很多疾病呢。
怪不得每天早上我上学的时候，天空中总是灰蒙蒙的一片，很难看到早上初升的太阳，雨后的天空中也没有彩虹，湛蓝深远的天空消失不见了，就连叽叽喳喳的小鸟也不愿意来到这样的地方，只有在儿歌中才有“太阳当空照，花儿对我笑，小鸟说。
”的景象。
你知道吗，大连她在哭泣，她哭人们这样伤害她，破坏她，把她原本美丽的面貌变成了这样丑陋。
我建议有车的家庭要减少车辆的使用，尽量步行或坐公交车，这样才能让我们的城市空气更清新。
我们大家都应该清楚知道空气污染的危害，然后赶紧行动起来，保护我们生存的环境，让空气污染不要伤害我们的家园!保护我们的家，从你我做起，从现在做起，从身边的小事赶紧做起!周六上午，我和爸爸妈妈一起骑车感受一下濮阳市的空气质量。
虽然天气寒冷，但我也感觉不到冷，因为我要做一次小小的空气调查员。
一路上我们有说有笑，当走到黄河路西段时，一股难闻的气味扑鼻而来。
我便问爸爸：“爸爸，这是什么气味呀，这么臭。

关于乌海市的空气污染英语作文初一
关于乌海市的空气污染英语作文初一全文共3篇示例，供读者参考篇1Air Pollution in My Hometown of WuhaiI am a 13-year-old student living in the city of Wuhai, located in the Inner Mongolia Autonomous Region of northern China. While my hometown has many wonderful aspects, such as its rich cultural heritage and beautiful natural scenery, it also suffers from a serious environmental issue – air pollution.Wuhai is an industrial city known for its coal mining, power generation, and chemical production industries. These industries have brought economic growth and job opportunities, but they have also taken a heavy toll on the air quality. On many days, a thick haze hangs over the city, obscuring the sun and making it difficult to breathe deeply or see very far.The main culprits behind Wuhai's dirty air are emissions from the city's many coal-fired power plants, factories, and vehicles. Coal is burned to generate electricity and power industrial processes, releasing harmful pollutants like sulfur dioxide, nitrogen oxides, and particulate matter into theatmosphere. Vehicle exhaust from the increasing number of cars and trucks on our roads also contributes significantly to the smog problem.I have witnessed firsthand the impacts this pollution can have. Some of my earliest childhood memories involve days when the air was so choked with smog that we were advised to remain indoors with windows closed. At school, we have had to cut short outdoor activities like physical education classes and recess periods due to severe air quality. Many of my peers suffer from respiratory illnesses like asthma that are exacerbated by the dirty air.Beyond the immediate health effects, there are broader consequences as well. The polluted air has stained many of our city's buildings, leaving them discolored and unsightly. The haze also obscures views of the beautiful grasslands and deserts that surround Wuhai on all sides. Tourists may be dissuaded from visiting due to the environmental issues.While the situation can seem bleak at times, I remain hopeful that solutions can be found. The local government has started taking some measures to address the crisis, such as shutting down some of the oldest, dirtiest coal plants and pushingfactories to install emission control equipment. However, much more needs to be done.I dream of a future where Wuhai has transitioned away from its heavy reliance on polluting coal power to adopt cleaner energy sources like solar, wind, and nuclear power. Our industrial base should modernize to implement state-of-the-artlow-emission technologies. Public transportation needs to be improved and made more accessible to reduce vehicle exhaust. Stricter environmental regulations must be put in place and actually enforced.Individual citizens also have an important role to play through our daily choices and habits. We should strive to minimize our energy usage at home by doing things like turning off lights when not needed and using energy-efficient appliances. Bike riding, walking, and use of public transit should be encouraged over private cars when possible. Even small acts like not burning trash can make a difference.In my English classes, we have discussed how air pollution is not just a local issue, but a global challenge facing cities around the world, especially in developing nations like China and India. Solving this crisis will require international cooperation, with countries sharing best practices, technology transfers, andstrategies for balancing environmental protection with economic growth.I hope that by the time I am an adult, the air over my beloved hometown will be clear enough that we can always see blue skies and breathe easily. The solution is not to stop industrial development entirely, as that engine has helped lift millions out of poverty. Rather, we must find a way to develop in a more sustainable, eco-friendly way that preserves our environmental health.While overcoming such a severe pollution problem will not be easy, I am confident that through a combination of government policy reforms, business innovation, citizen engagement, and global collaboration, we can eventually restore clean air to Wuhai. Every time the hazy smog clears for a day or two, offering a glimpse of the beautiful natural scenery, it gives me hope that bluer skies are indeed possible. With perseverance and commitment from all of us, that hope can become a reality.篇2Air Pollution: The Unseen Threat Looming Over Wuhai CityAs a young student growing up in Wuhai City, located in the Inner Mongolia Autonomous Region of China, I have witnessedfirsthand the impacts of air pollution on our daily lives. The once pristine skies that we used to gaze upon during our childhood have gradually become obscured by a thick veil of smog, casting a gloomy shadow over our city.Wuhai City, known for its rich coal reserves and heavy industrial activities, has unfortunately become a hotspot for air pollution. The burning of fossil fuels, coupled with the emissions from factories and vehicles, has led to a significant deterioration in air quality. This invisible threat not only affects our immediate surroundings but also poses serious risks to our health and well-being.On many occasions, I have found myself struggling to breathe during particularly hazy days. The acrid smell of pollutants permeates the air, stinging my nostrils and causing discomfort in my lungs. It is a distressing reality that many of my classmates and I have had to endure, often resulting in respiratory issues and missed school days due to illness.The impact of air pollution extends far beyond our physical well-being. It has also cast a shadow over our daily routines and leisure activities. Gone are the days when we could freely engage in outdoor sports or simply enjoy the fresh air without the fear of inhaling harmful pollutants. The once-vibrant playgrounds andparks that were once our havens of joy have now become hazardous zones, forcing us to seek indoor alternatives for recreation.Moreover, the effects of air pollution transcend the boundaries of our city. The thick smog that envelops Wuhai City has become a stark reminder of the broader environmental crisis we face as a society. The burning of fossil fuels not only contributes to localized air pollution but also exacerbates the global issue of climate change, putting our planet's delicate ecosystems at risk.As a concerned student, I cannot help but wonder about the long-term consequences of this unseen threat. What will become of our beloved city if we continue to neglect this pressing issue? Will future generations be robbed of the opportunity to experience the beauty of a clear sky and breathe clean air?It is imperative that we, as citizens of Wuhai City, take decisive action to address this growing concern. We must hold our local authorities accountable and demand stricter regulations on industrial emissions and the adoption of cleaner energy sources. Furthermore, we should encourage the use of public transportation and promote eco-friendly modes oftransportation, such as cycling and walking, to reduce our carbon footprint.Education also plays a crucial role in combating air pollution. By raising awareness among students like myself and the wider community, we can foster a deeper understanding of the environmental impact of our actions and nurture a sense of responsibility towards preserving our planet's well-being.In conclusion, air pollution in Wuhai City is a pressing issue that demands immediate attention and collective action. As a student and a concerned citizen, I implore my peers, educators, and local authorities to join forces in addressing this unseen threat. Together, we can work towards restoring the once pristine air quality of our city and ensuring a healthier, more sustainable future for generations to come. Let us not allow the haze of pollution to obscure our vision of a better tomorrow.篇3Air Pollution: A Choking Issue for My Hometown WuhaiAs a middle school student growing up in Wuhai, a city in the Inner Mongolia Autonomous Region of China, I have witnessed firsthand the severe air pollution that plagues our hometown. The once pristine blue skies have been tainted with aperpetual haze, casting a gloomy shadow over our daily lives. It is a issue that weighs heavily on my mind and the minds of many of my classmates and fellow citizens.Wuhai, known as the "Birthplace of Chinese Industry," has long been a hub for coal mining, power generation, and heavy industry. While these industries have fueled economic growth, they have also brought about a steep environmental cost. The burning of coal for energy production is a major contributor to the city's air pollution, spewing out harmful pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter.On many days, the air quality index (AQI) in Wuhai soars past the "unhealthy" level, indicating that the air is hazardous to breathe. The thick smog obscures visibility, making it difficult to see buildings just a few blocks away. It's a disheartening sight, especially when we recall the stories our grandparents tell of the clear, crisp air they once enjoyed in their youth.The impact of air pollution on our health is a grave concern. Exposure to high levels of particulate matter and other pollutants can cause respiratory issues, exacerbate conditions like asthma and bronchitis, and even increase the risk of lung cancer and heart disease. I have classmates who suffer from persistentcoughs and frequent bouts of illness, likely linked to the poor air quality we breathe every day.Recess and physical education classes, which should be opportunities for us to exercise and enjoy the outdoors, often become indoor activities due to the hazardous air conditions. It's a heartbreaking reality when we have to forego the simple pleasures of running and playing outside because the air is too polluted to safely breathe.Beyond the immediate health effects, air pollution also poses long-term consequences for our environment and quality of life. Acid rain, a byproduct of sulfur dioxide emissions, has damaged crops and vegetation in the surrounding areas, threatening the livelihoods of local farmers. The persistent haze also obscures the natural beauty of the region, robbing us of the opportunity to fully appreciate the landscapes that once drew visitors from far and wide.While the situation may seem bleak, I remain hopeful that positive change is possible. Our local government has taken steps to address the issue, implementing stricter emissions standards for industries and promoting the use of cleaner energy sources like natural gas and renewable energy. However, more needs to be done, and it will take a concerted effort from allstakeholders – industries, policymakers, and citizens alike – to truly tackle this challenge.As students, we have a crucial role to play in raising awareness and advocating for a cleaner, healthier environment. In our schools, we have organized environmental clubs and campaigns to educate our peers and communities about the dangers of air pollution and the importance of sustainable practices. We have also participated in tree-planting initiatives and cleanup events, doing our part to contribute to a greener Wuhai.Furthermore, we are learning about innovative technologies and solutions that could help mitigate air pollution, such as carbon capture and storage, advanced air filtration systems, and the development of more efficient and cleaner energy sources. By staying informed and embracing these advancements, we can be part of the solution as we grow into the next generation of leaders, policymakers, and environmental advocates.Air pollution is not just an issue for Wuhai; it is a global challenge that requires collective action. By raising our voices and taking steps to address this problem, we can create a better future for our city, our country, and our planet. It is a daunting task, but one that we must confront head-on, for the sake of ourhealth, our environment, and the generations that will follow in our footsteps.As I look out the window at the hazy skyline, I am reminded of the urgency of this issue. But I also feel a sense of determination, knowing that we have the power to make a difference. With education, innovation, and a shared commitment to sustainability, we can reclaim the clear skies that once graced our beautiful city, ensuring that future generations can breathe freely and appreciate the natural wonders that surround us.。

空气环境与健康作文600字
空气环境与健康作文600字Air pollution is a serious issue that has a direct impact on our health. Breathing in polluted air can lead to various respiratory problems, cardiovascular diseases, and even cancer. In this essay, I will discuss the relationship between air quality and health, and the measures we can take to improve the air we breathe.Firstly, air pollution is caused by both natural and human activities. Natural sources include volcanic eruptions, dust storms, and forest fires. These events release harmful particles and gases into the atmosphere, contributing to poor air quality. On the other hand, human activities such as industrial emissions, vehicle exhaust, and burning of fossil fuels are major contributors to air pollution. For instance, factories release pollutants like sulfur dioxide and nitrogen oxides, which can cause respiratory issues when inhaled.Secondly, the effects of air pollution on our healthare significant. Fine particulate matter, known as PM2.5,is one of the most harmful pollutants. These tiny particles can easily enter our respiratory system and cause lung inflammation, leading to asthma attacks and other respiratory diseases. Additionally, long-term exposure to air pollution can increase the risk of heart diseases and lung cancer. For example, a study conducted in China found that people living in areas with high levels of air pollution had a higher mortality rate from cardiovascular diseases.Furthermore, children and the elderly are more vulnerable to the health effects of air pollution. Children have developing respiratory systems, making them more susceptible to the harmful effects of pollutants. Elderly individuals often have pre-existing health conditions, and air pollution can worsen their symptoms. For instance, a study in the United States revealed that older adultsliving in areas with high levels of air pollution had a higher risk of hospitalization for respiratory diseases.To improve air quality and protect our health, severalmeasures can be taken. Firstly, we should reduce our reliance on fossil fuels and promote the use of renewable energy sources. This can be achieved by investing in solar and wind power, as well as encouraging the use of electric vehicles. Additionally, stricter regulations should be implemented to control industrial emissions and vehicle exhaust. For example, factories can be required to install pollution control devices and vehicles can undergo regular emission tests.Furthermore, individuals can contribute to improvingair quality by making small changes in their daily lives. For instance, using public transportation or carpooling can help reduce vehicle emissions. Planting trees and creating green spaces can also help in absorbing pollutants and improving air quality. Moreover, raising awareness about the importance of clean air and its impact on health is crucial. Education campaigns and community initiatives can play a significant role in promoting behavior change and encouraging everyone to take responsibility for the air we breathe.In conclusion, air pollution poses a serious threat to our health. It is caused by both natural events and human activities. The health effects of air pollution are significant, particularly for vulnerable populations suchas children and the elderly. To improve air quality, weneed to reduce our reliance on fossil fuels, implement stricter regulations, and make individual efforts to reduce pollution. By taking these measures, we can ensure a healthier future for ourselves and the generations to come.中文回答：空气污染是一个严重的问题，对我们的健康有直接影响。
空气污染作文
空气污染作文本文是关于作文大全的，仅供参考，如果觉得很不错，欢迎点评和分享。
空气污染作文（一）我的家乡在千岛湖，这儿有一片片郁郁葱葱的森林，清澈见底的湖水，湛蓝深远的天空，清新甜润的空气。
可惜，家乡人一些无意识的行为，还在影响着这儿的环境，比如过年过节燃放烟花爆竹，就严重地污染了空气（今年算我们家污染的空气最多了）。
就拿我们家来说说吧。
除夕夜那天，在吃年夜饭前，爸爸先去楼下放鞭炮。
噼里啪啦鞭炮声响起，顷刻间楼下变成了天庭，看不到地面，仿佛全是云，我就像置身在云海里，浓浓的硝烟弥漫着，给人一种窒息的感觉。
晚上就有更大的浓烟了。
我们先看了联欢晚会……随着电视节目的倒计时，“五、四、三、二、一”，几乎同时我和爸爸一起抬起了鞭炮去楼下放，迎接新年的到来。
噼里啪啦，只看见鞭炮爆炸的火花。
遭了，没法呼吸新鲜空气了。
我以最快的速度跑进了家，关上门、关上窗户。
很用力的喘气儿。
那一夜，鞭炮声一直响了几个小时，闹得我整夜没睡好觉。
不是梦见我炸伤别人，就是别人炸伤我，害得我总是惊醒。
我觉得要想让环境重新好起来，应该少放鞭炮、少抽烟、让我们的环境像原先那样美丽，迷人吧！空气污染作文（二）所谓“大气污染”是指有害物质进入大气，对人类和生物造成危害的现象。
如果对它不加以控制和防治，将严重的破坏生态系统和人类生存条件。
大气污染有的是由于森林火灾、火山爆发等自然因素造成的；有的则是由汽车尾气、工业废气、烟尘、爆炸等人为因素造成的，其中人为因素对大气的污染是主要的，尤其是现代交通运输和工业生产对城市大气造成的污染更为严重。
因此人们对大气污染问题越来越关切。
造成大气污染的物质有：一氧化炭CO、二氧化硫SO2、一氧化氮NO、臭氧O3以及烟尘、盐粒、花粉、细菌、苞子等。
距地面几十米的近地面层大气，是人类和生物的生存空间。
这一层空气质量的好坏直接影响着人类的生产和生活。
近年来，由于交通运输业的发展，排放出的大量汽车尾气与空气中的一些物质成分发生化学反应，生成对人体十分有害的一氧化氮、臭氧、乙醛等新物质。
保护环境600字优秀作文(精选10篇)
保护环境600字优秀作文(精选10篇)保护环境600字优秀作文篇1老师们、同学们：大家好!在我们的生活中，有许多美丽的景色值得我们去欣赏，可是因为人们的环保意识薄弱破坏了这一道道美景，我们要行动起来，保护环境。
此刻的污染有许多，其中空气污染是最魁祸首。
此刻雾霾PM2.5属于最严重的空气污染，我国首都北京因雾霾空气污染指数到达600以上!所以空气污染对我们的环境破坏相当严重，到底是什么产生了雾霾呢让我们来揭晓答案。
雾霾主要是因为汽车尾气的排放和烟花爆竹所产生的，可雾霾有弱点。
他像烟花爆竹一样只要有水它就消失了，此刻准备用人工降雨来消除雾霾。
期望国家能早日消除雾霾这一困惑。
其二就是水污染。
水是生命之源几乎世间万物都离不开他，可就是有些人破坏了水。
使环境受到破坏，使人的生命受到伤害。
为什么这样说呢是因为植被吸收了有污染的水慢慢的开始枯萎、死亡，人喝了虽然不会死但也对身体有害。
这些水从何而来呢那要看工厂，有些工厂把一些废弃的石油颜料排进河里，这样清澈的小河变成了臭水沟。
还有那可怕的白色污染，许多人把吃完的饭盒还有塑料袋投进河里，这就是河水变脏的原因。
还有的人浪费水，关水龙头时不拧紧、破坏消防栓、踢水管让水很多流失。
虽然世界上海水占全球总面积的三分之二，可世界上还有许多缺水国家其中我国就是里面的一员，所以我们要节俭用水。
记住一句话：“别让人的眼泪，成为世界上的最终一滴水!”最终，我向大家倡议少使用汽车，少燃放烟花爆竹。
少用塑料袋，节俭用水。
保护环境，人人有责!保护环境600字优秀作文篇2敬爱的市长伯伯：您好!我是__区__小学四年级的小男生，也是一名环保小志愿者，地球的哭泣让我伤心，不知你是否看到了地球的伤痛?随地吐痰的人、乱扔废旧电池的人，让地球中了病菌的毒，乱扔垃圾的人尤其是垃圾袋到处飞扬，让地球脏乱不堪……市长伯伯，从品德课上我还知道了，鸟类数量的不断下降，原来是乱砍滥伐让鸟儿们缺少了居住的家园;工厂里排放的污水污染了河里、海里的鱼，大批的鱼类中了毒，鸟吃了鱼自然就会死去，大批的鸟死去，当然也就破坏了生物规律中的食物链，这太可怕了!为了建设我们无污染的家园，为了让地球恢复往日的欢笑和健康，请接受我的建议：1、善待地球，就是善待我们自己，为每家工厂建造一个污水处理管道。

大气污染的作文600字
大气污染的作文600字所谓“大气污染”是指有害物质进入大气，对人类和生物造成危害的现象。
如果对它不加以控制和防治，将严重的破坏生态系统和人类生存条件。
这里给大家分享一些关于大气污染的作文，供大家参考。
大气污染的作文1就最近这几年来看，随着各地区的经济迅猛发展，环境污染问题也越来越严重，保护环境，维持生态平衡也成为了我们每个公民应尽的责任和义务，也是为了社会更好发展的一项重要举措!何为环境?从哲学的角度来看，所谓环境，主要指我们所研究的.主体周围的一切情况和条件。
对于人来说，环境是指人生活于其中，并能影响人的一切外部条件的综合。
人的生活离不开好的环境，在人类几百万年的历史进程中，环境对开创人类文明和进步发挥着巨大作用。
大气资源、水资源、土地资源等等，都是让人类得以生存的物质基础;而森林资源、矿藏资源等资源又为人类的不断发展提供物质，创造出地球上高度的人类文明。
但是，人类在开发利用环境资源的同时，也对自己的生存环境产生了一系列环境问题。
在我们身边就有很多污染环境的污染物，例如说：大量的生活废弃品，塑料袋(也称白色垃圾)，一次性木筷，一次性饭盒，果皮纸屑。
污染物对环境来说，毫无疑问，肯定有很大的危害，例如动物的腐烂的尸体会影响环境卫生，而且还会滋生细菌。
饭店、餐馆认为很卫生的一次性木筷，使用后随便一扔，影响了市容，破坏了环境。
现在像我们柳疃镇、青乡乡，最近电网部门纷纷撤除喷水机器的使用。
喷水机的使用对环境的污染更加恶化、污染了水资源对人们的身体健康危害甚大。
人类的活动会使大量的工业、农业和生活废弃物排入水中，使水受到污染。
又例如说，我们北部渤海湾受到工业、印染厂的废弃物排放大量鱼虾死亡，地区农民上海捕鱼，鱼的体内含有大量化学物质对人们的身体健康造成了危害。
据资料统计，目前，全世界每年约有4200多亿立方米的污水排入江河湖海，污染了5.5万亿立方米的淡水，这相当于全球径流总量的14%以上。
1984年颁布的中华人民共和国水污染防治法中为“水污染”下了明确的定义，即水体因某种物质的介入，而导致其化学、物理、生物或者放射性等方面特征的改变，从而影响水的有效利用，危害人体健康或者破坏生态环境，造成水质恶化的现象称为水污染。
大气污染作文
大气污染作文英文回答：Air pollution, a pervasive issue plaguing modern societies, has become a significant threat to human health and the environment. It arises from the release of harmful gases, particulate matter, and toxic substances into the atmosphere, primarily through human activities such as industrial emissions, vehicle exhaust, and energy production.The consequences of air pollution are far-reaching, impacting both human well-being and ecological systems. For humans, exposure to polluted air can lead to respiratory problems such as asthma, bronchitis, and lung cancer. Cardiovascular diseases, stroke, and premature death are also linked to air pollution. Additionally, children and the elderly are particularly vulnerable to the adverse effects of air pollution.Air pollution also has detrimental impacts on ecosystems. It can damage crops and forests, reduce biodiversity, and disrupt natural habitats. Acid rain, caused by the release of sulfur dioxide and nitrogen oxides, acidifies lakes and rivers, harming aquatic life. Ozone depletion, a consequence of chlorofluorocarbons (CFCs) and other ozone-depleting substances, weakens the Earth's protective ozone layer, increasing the risk of skin cancer and cataracts.Combating air pollution requires a multifaceted approach. Governments, industries, and individuals mustwork together to reduce emissions and improve air quality. Regulations on industrial emissions, fuel efficiency standards for vehicles, and the promotion of renewable energy sources are essential steps. Individuals can also contribute by reducing their carbon footprint throughenergy conservation measures, adopting sustainable transportation options, and advocating for environmental policies.International collaboration is crucial in addressingthe transnational nature of air pollution. Transboundaryair pollution can impact nations far from the original source of emissions. Cooperation among countries is necessary to establish common standards, share best practices, and coordinate efforts to reduce air pollutionon a global scale.中文回答：大气污染作文。

【篇一：大气污染保护环境作文】最近，我对我家居住的卫校小区的空气质量进行了调查。
经过这次调查，我发现小区的空气遭到了严重的污染，主要污染源是：小区旁的餐馆排放出的油烟;过路的车辆排放出的废气;附近的梅峰寺后山有人在烧垃圾，烟雾弥漫。
正是这些有害气体污染了原本清新的空气。
这些被有害气体污染了的空气，会对人体健康产生不利的影响，还会对周围的花草树木的生长造成了极坏的影响。
保护环境，人人有则。
为了防止家乡空气受到污染，我想我们大家可以做好多事，为防止家乡空气受到污染献自己的一份力量。
第一，可以给小区旁的餐馆写一份建议书，建议餐馆把油烟经过处理再排放到空气中去。
还要改进汽车发动机，减少废气的排放;第二，大家要爱护花草树木，因为花草树木是氧气制造厂，空气过滤器，可以有效净化空气;第三，我们要注意搞好环境卫生，不乱扔垃圾，不随地吐痰等。
啊!我们从小养成保护环境的好习惯，养成良好的文明卫生习惯。
大家动员起来吧!让我们生活的环境更加美好!【篇二：大气污染保护环境作文】我们生活的地球正遭受着严重的空气污染。
工厂排放的废气、燃烧的垃圾、汽车的尾气等都是污染大气的祸源。
它们时刻侵袭着我们的呼吸道和肺，使呼吸系统的发病率逐年上升。
当空气轻微污染时，人体吸入的空气可以由鼻腔里的鼻毛除去部分灰尘，再由鼻腔里的黏液和各类支气管里的黏液将灰尘粘连住。
气管和支气管内的纤毛有几千万根，它们每秒约摆动12次，像“清洁工”一样从下向上推扫呼吸道里的黏液，直至咽喉部，再通过咳嗽咳出体外。
当空气严重污染时，呼吸道的净化作用将降低，甚至完全丧失。
在这种情况下，呼吸道和肺易受病菌的侵袭而患各种疾病。
由于种种原因，空气污染还在加剧。
如果不能解决空气污染的问题，恐怕真有一天，人类只能带着口罩生活。
关于空气污染的原因解决措施英语作文初中
Air Pollution: Causes, Effects, and SolutionsAir pollution is a serious problem that affects our health and the environment. It is caused by various factors, including industrial emissions, vehicle exhaust, and agricultural activities. The harmful substances releasedinto the air can lead to respiratory problems, heart diseases, and even cancer. Therefore, it is crucial to understand the causes of air pollution and take effective measures to address it.One of the main causes of air pollution is industrial emissions. Factories and power plants release large amounts of harmful gases and particles into the air, causingserious pollution. To reduce these emissions, companies should invest in clean energy and energy-efficient technologies. Governments should also implement strict regulations and monitor factories and power plants toensure they comply with emission standards.Vehicle exhaust is another significant source of air pollution. The increasing number of vehicles on the road leads to higher levels of harmful gases and particulate matter in the air. To address this problem, people shouldbe encouraged to use public transportation, cycle, or walk instead of driving private cars. Governments should also provide incentives for the use of electric and hybrid vehicles and improve the public transportation system.Agricultural activities, especially the excessive use of fertilizers and pesticides, also contribute to air pollution. These chemicals can volatilize into the air and affect air quality. To reduce their use, farmers should be trained on sustainable farming practices and encouraged to adopt organic farming methods. Governments should provide subsidies and incentives for the use of environmentally friendly agricultural practices.In addition to these measures, individuals can also contribute to reducing air pollution by making small changes in their daily lives. For example, they can reduce energy consumption by using energy-efficient appliances and turning off lights and fans when not in use. They can also recycle and compost waste to reduce the amount of garbage sent to landfills.In conclusion, air pollution is a complex problem that requires collective efforts from individuals, communities,and governments. By understanding the causes of airpollution and taking effective measures to address it, we can improve air quality, protect our health, and preserve the environment for future generations.**空气污染：原因、影响与解决方案**空气污染是一个严重影响我们健康和环境的问题。

关于空气污染的初中作文600字：大气污染
导读：本文关于空气污染的初中作文600字：大气污染，仅供参考，如果觉得很不错，欢迎点评和分享。
所谓“大气污染”是指有害物质进入大气，对人类和生物造成危害的现象。
如果对它不加以控制和防治，将严重的破坏生态系统和人类生存条件。
大气污染有的是由于森林火灾、火山爆发等自然因素造成的;有的则是由汽车尾气、工业废气、烟尘、爆炸等人为因素造成的，其中人为因素对大气的污染是主要的，尤其是现代交通运输和工业生产对城市大气造成的污染更为严重。
因此人们对大气污染问题越来越关切。
造成大气污染的物质有：一氧化炭CO、二氧化硫SO2、一氧化氮NO、臭氧O3以及烟尘、盐粒、花粉、细菌、苞子等。
距地面几十米的近地面层大气，是人类和生物的生存空间。
这一层空气质量的好坏直接影响着人类的生产和生活。
近年来，由于交通运输业的发展，排放出的大量汽车尾气与空气中的一些物质成分发生化学反应，生成对人体十分有害的一氧化氮、臭氧、乙醛等新物质。
悬浮在大气中的各种气溶胶粒子，按其大小可分为降尘和飘尘。
其中降尘的粒子较大，直径大于10微米，它的自然沉降率较快。
它与人类支气管炎的死亡率和农业减产有很大关系;飘尘粒子较小，直径一般在0·1—1·0微米。
其自然沉降率很小，故悬浮在大气中的生命史较长。
随着粒子的减小有毒元素的浓度将增加。
通常小于0·3微米的飘尘能直接吸入肺泡，如长期积累，会损害呼吸机能，引起哮喘、肺气肿、矽肺和肺癌等不治之症。
由于飘尘的污染期长和毒性强，因此它的危害性大。
当大气中气溶胶粒子增加到一定程度以后，就会出现烟雾弥漫，能见度降低，太阳辐射减弱等现象。
近地面层大气污染程度与气象条件密切相关，存在着明显的季节变化和日变化。
一般冬季的早晨和傍晚在无风的天气条件下空气污染最为严重。
夏季由于空气层结不稳定，污染物易向高空扩散，因此一般污染不会太严重。
