环境污染概述
由于人们对工业高度发达的负面影响预料不够,预防不利,导致了全球性的三大危机:资源短缺、环境污染、生态破坏.人类不断的向环境排放污染物质.但由于大气、水、土壤等的扩散、稀释、氧化还原、生物降解等的作用.污染物质的浓度和毒性会自然降低,这种现象叫做环境自净.如果排放的物质超过了环境的自净能力,环境质量就会发生不良变化,危害人类健康和生存,这就发生了环境污染.
环境污染有各种分类：
按环境要素分：大气污染、水体污染、土壤污染.
按人类活动分：工业环境污染、城市环境污染、农业环境污染.
按造成环境污染的性质、来源分：化学污染、生物污染、物理污染（噪声污染、放射性、电磁波）固体废物污染、能源污染.
环境污染会给生态系统造成直接的破坏和影响,如沙漠化、森林破坏、也会给生态系统和人类社会造成间接的危害,有时这种间接的环境效应的危害比当时造成的直接危害更大,也更难消除.例如,温室效应、酸雨、和臭氧层破坏就是由大气污染衍生出的环境效应.这 种由环境污染衍生的环境效应具有滞后性,往往在污染发生的当时不易被察觉或预料到,然而一旦发生就表示环境污染已经发展到相当严重的地步.当然,环境污染的最直接、最容易被人所感受的后果是使人类环境的质量下降,影响人类的生活质量、身体健康和生产活动.例如城市的空气污染造成空气污浊,人们的发病率上升等等；水污染使水环境质量恶化,饮用水源的质量普遍下降,威胁人的身体健康,引起胎儿早产或畸形等等.严重的污染事件不仅带来健康问题,也造成社会问题.随着污染的加剧和人们环境意识的提高,由于污染引起 的人群纠纷和冲突逐年增加.
目前在全球范围内都不同程度地出现了环境污染问题,具有全球影响的方面有大气环境污染、海洋污染、城市环境问题等.随着经济和贸易的全球化,环境污染也日益呈现国际化趋势,近年来出现的危险废物越境转移问题就是这方面的突出表现.
保护地球,从我做起

A global environment problems, 10
1, climate warming
2, ozone depletion
3, biodiversity decrease
4, acid rain spread
5, forest plummeted
6, land desertification
7, air pollution
8, water pollution
9, Marine pollution
10, solid waste pollution
Second, our country environment conditions
1, belong to MeiYanXing pollution, air pollution and acid hardest by dust pollution levels in intensified.
2, acid rain is mainly distributed in the south of the Yangtze, east of the qinghai-tibet plateau area and the sichuan basin. Huazhong area of acid rain pollution heaviest.
Three rivers, lakes library waters is universally different levels of pollution, except some inland rivers and large reservoir outside, pollution into aggravating trend, developed industrial town near the water pollution is very outstanding.
4, seven water system (the zhujiang river, the Yangtze, yellow, huaihe and HaiLuanHe, liaohe, the songhua river) in the Yellow River, liaohe basin, the songhua river, the water pollution is serious.
5, large freshwater lakes phosphorus, total nitrogen pollution area wide, eutrophication serious.
6, four sea area in bohai sea and east China sea pollution is heavier, nanhai lighter.
7 and fishery waters of degradation of ecological environment condition no fundamental change, and is aggravating trend.
8, urban environment pollution is aggravating trend.
9, the city ground water pollution is serious, the general trend of worsening. Most rivers are polluted by different degree.
10, national 2/3 of the rivers and more than 1,000 million hectares of farmland contaminated.
3 and the previous environment day theme
1974: only one earth
In 1975: human habitation
1976: water, life's important resources
In 1977: focuses on ozone depletion, soil erosion, soil degradation and denudation
1978: without disrupting the development
In 1979: in order to children and the development of future - no damage.
1980: new 10 years, new challenges - without disrupting the development
In 1981: protection of groundwater and the human and the human food chain, Prevent toxic chemical pollution

1983: management and processing hazardous waste, prevent to acid rain
In 1996: our earth, homes, residence
1997: for life on earth
Environmental pollution overview
As people have highly developed industry negative impact expected enough, prevent adverse, led to the global three crisis: resource shortage, environment pollution and ecology destruction to environment. Human continuous discharge pollutants. But because the atmosphere, water, soil, etc, the diffusion, diluted, REDOX, biological degradation function. Pollutant concentration and toxicity naturally decreases, the phenomenon is called environment since clean. If emissions of material beyond the environment of self-purification capability, the environmental quality adverse changes will occur, harmful to human health and survival, this occurs pollution of the environment.
Environmental pollution have various classification:
According to the environmental elements points: air pollution, water pollution, soil pollution.
According to human activity points: industrial pollution of environment, urban environment pollution, the agricultural environment pollution.
According to the properties, cause environmental pollution source points: chemical pollution, biological pollution and physical pollution (noise pollution, radioactive, electromagnetic wave) solid waste pollution, energy pollution.
Environmental pollution will give ecosystem cause immediate destruction and effects, such as desertification, forest destruction, also can give ecosystem and human society caused by indirect harm, sometimes this indirect environmental effects of hazard ratio was directly caused by more harm, but also more difficult to eliminate. For example, the greenhouse effect, acid rain, and ozone depletion by air pollution is derived from the environmental effects. This kind of derivatives by environmental pollution of the environment, often lag effect has not occurred in pollution was expected to be perceived or however if it happens, said environmental pollution has developed to a quite serious. Of course, the environmental pollution of the most direct, most vulnerable to perceive the consequence is that the human environment quality descend, affect human body health and quality of life and production. For example city's air pollution caused by the incidence of stale air, people rise, etc. Water pollution makes the water environmental quality deterioration, drinking water quality general decline, threatening the health of the human body, cause fetal premature birth or deformity, etc. Severe pollution incident brings not only health problem, also caused social problems. Along with the pollution rising and the people to the improvement of environmental awareness due to pollution caused by the crowd disputes and conflicts increases year by year.
At present in the global scope are different degree occurs the pollution of environment issues, a global influence aspects have atmospheric pollution, Marine pollution, urban environmental issues. Along with the globalization of economy and trade, environmental pollution is also increasingly presents the trend of internationalization, recent tran boundary movements of hazardous wastes problem is this aspect of the outstanding performance.
