1、,环境保护,Environmental pollution and environmental protection,4月22日世界地球日 6月5日世界环境日,保护环境,April 22 Earth Day,June 5 World Environment Day,地球永远与人息息相关，永远与大地母亲同在,我们一直在努力向前,The earth is closely related with people forever, forever and Mother Earth with the,地球病了，需要我们的关爱,Earth sick, and need our care,下面请欣赏我们人类

2、的杰作,做好心理准备哦。,Below, please enjoy the masterpiece of our humanity,丹麦当男的长到十八岁的时候就会用屠杀鲸鱼来证明自己长大了，这样真的能证明自己的勇气吗？,Denmark when men grow to eighteen years of age when I would have to prove himself killing whales grow up, this really can prove his courage? ? ?,这个我不解释，你们懂得,This I do not explain, you know,可吸

3、入颗粒物来源:,我们每天就生活在这环境中,Every day we live in this environment,Respirable particulate matter sources,沙尘暴:,Sandstorm,光化学烟雾,Photochemical smog,一般认为,酸雨是由于燃烧高硫煤排放的二氧化硫等酸性气体进入大气后,造成局部地区大气中的二氧化硫富集,在水凝结过程中,溶解于水形成亚硫酸,然后经某些污染物的催化作用及氧化剂的的氧化作用生成硫酸,随雨水降下形成酸雨. 酸雨的pH值一般少于5.6.,酸雨,（Acid rain）,Generally believed that ac

4、id rain is sulfur dioxide emissions from burning high-sulfur coal and other acid gases into the atmosphere, resulting in localized concentration of sulfur dioxide in the atmosphere, the water condensation process, dissolved in water to form sulfurous acid, and then by some of the pollutants catalyti

5、c oxidation and oxidant to generate sulfuric acid, with water down the formation of acid rain. The pH of acid rain is generally less than 5.6.,Chemical yellow smoke,在距离地面约25Km处，有一层由太阳强辐射造成的臭氧层，它能吸收太阳紫外线，使大部分有害射线不能到达地球表面，保护地球生物免遭伤害，是地球的“保护伞”。 20世纪70年代以来，人们大量使用冰箱、空调，释放出大量的氟氯烃化合物（氟利昂），上升到臭氧层，通过光化学反应大量消

6、耗臭氧。1979-1990年，全球臭氧总量大致下降3%， 南极附近臭氧量减少尤为严重，出现了全球臭氧量最低值，大约低于全球平均值的30%-40%，相对于其他地区来说，就象是一个洞，这就是“南极臭氧洞”。,臭氧空洞,Fog ozone hole,At the ground at a distance of about 25Km, with a layer of strong radiation from the sun, the ozone layer, it can absorb the suns ultraviolet light, so most of the harmful rays c

7、an not reach the Earths surface, protection from harm life on Earth, the Earths umbrella. Since the 1970s, a large number of people using refrigerators, air conditioners, releasing large amounts of HCFC (Freon), up to the ozone layer, ozone consumption by a large number of photochemical reactions. 1

8、979-1990, global total ozone decrease roughly 3%, Near the Antarctic ozone reduction is particularly serious, there is a global minimum ozone values ?lower than the global average of about 30% -40%, compared to other regions, just like a hole in it is the Antarctic ozone hole.,为了保护臭氧层，国际社会要求各国减少并逐步禁

9、止氟氯烃等消耗臭氧层的物质的排放，发达国家要求到2000年停止使用氟氯烃，发展中国家则在2016年冻结使用，2040年淘汰； 并组织人力物力研制新型的制冷系统。,臭氧层的保护,Protection of the ozone layer,In order to protect the ozone layer, the international community for countries to reduce and phase out HCFCs and other ozone depleting substances emissions, developed countries, dema

10、nds to stop the use of HCFCs in 2000, developing countries to use freeze in 2016, 2040, out; And the organization of human resources development of new cooling systems.,越美丽，越可怕,The more beautiful, more terrible,美好的森林,如今，只能是世外桃源。,Beautiful forest,Today, the only paradise,被称为“白色污染”的，我们目前常见常用并常说的一次性“塑料

11、餐具” 。 当白色的、轻轻的但却有相当厚度的塑料一次性餐具进入我们的生活时，我们着实为这方便又实用的小东西叫过好它因不能重复使用而卫生，不需要洗涤而方便，等等。 但很快，我们就认识到，这类塑料餐具，虽说在用后被我们扔掉了，但却永远成为这个地球上的无机物垃圾。用专业术语说就是，自然状态下不能分解。于是，这给人类带来方便的东西也给地球带来麻烦。从农村到城市，从田野到山林，从小河沟到扬子江，到处可见废弃的一次性塑料餐具。于是，人们开始呼吁治理这“白色污染”，消灭这“白色污染公害”。,白色污染,White pollution,Known as the white pollution, commonly

12、 used and often we say one-off plastic tableware. When the white, gently but considerable thickness of the plastic disposable tableware into our lives, we are really convenient and practical for this little thing called too good - it can not be reused due to the health, do not need to wash and easy

13、, and so on. But soon, we recognized that such plastic cutlery, although in use after we threw away, but never on this earth to become inorganic garbage. Jargon that is, the state of nature can not break down. So, it brings convenience to mankind things to trouble the earth. From rural to urban, fro

14、m the fields to the mountains, small rivers to the Yangtze River, abandoned everywhere disposable plastic tableware. As a result, people began to call for governance which white pollution, to eliminate the white pollution hazards.,海边,Thank you watch,污染治理(Pollution control：,控制污水任意排放，对污水进行净化处理，改善用水制度，

15、研究无污染新工业，合理、科学地施用化肥、农药。,Control any discharge of sewage, the sewage purification, improved water systems, research new industrial pollution, rational, scientific application of fertilizers and pesticides,CO2,CO,SO2,NOX,NH3,酚类、烟雾、烟尘、放射性稀有气体氡、电磁波、螨虫、细菌、病毒等,Phenols, smoke, dust, radioactive noble gas r

16、adon, electromagnetic waves, mites, bacteria, viruses, etc.,拯救绿色,地球人的行动,防治措施:保持室内清洁通风 对电器辐射采取防护措施,并保持距离 厨房要有通风换气设施 宠物要经常洗浴,养成良好的排便习惯,并注意及时清除 女性朋友要慎用化妆品和日常化学用品 建议男士少抽烟或不抽烟 Control measures: Keep indoor air clean Of electrical radiation to take protective measures and keep their distance Kitchen facilities have ventilation Pets should always bathing, develop good bowel habits, and attention to the timely removal A female friend to be used with caution cosmetics and daily chemicals Suggested men s
