Summary of environmental pollution due to the negative effects of highly developed industrial expected is not enough, to prevent adverse, led to the global crisis of the big three: resource shortage, environment pollution and ecological destruction. Human constantly pollutants released into the environment.But due to the spread of the atmosphere, water, soil, etc, dilution, oxidation reduction, the role of biological degradation and so on.The pollutants concentration and toxicity will naturally reduce, this phenomenon is called environmental self-purification.If emissions of material more than the environment self-purification capability, environmental quality will change bad, harm to human health and survival, which the environmental pollution.Environmental pollution has all kinds of classification: according to the environmental elements: air pollution, water pollution, soil pollution.The points of human activities: industrial pollution, urban environment pollution, agricultural pollution of the environment.According to the nature of the environmental pollution, source points: chemical pollution, physical pollution, biological pollution, noise pollution, radioactive, electromagnetic waves) pollution by solid waste, energy and pollution.Environment pollution can cause direct damage to the ecological system and influence, such as desertification, forest destruction, will also be an indirect damage to the ecosystem and human society, sometimes the indirect environmental effect of harm does more harm than was caused by the direct, and much harder to eliminate.For example, the greenhouse effect, acid rain and ozone depletion is derived by atmospheric pollution environment effect.This kind of environmental effect has a hysteresis derived from environmental pollution, often occur in pollution is not easy to detect or anticipated at the time, however, in the event of means have been developed to the point of serious environmental pollution.Pollution of the environment, of course, the most direct, the most vulnerable to the feelings of the consequences of is to make the quality of human environment, affect the quality of human life, health and production activities.The city's air pollution cause air pollution, for example, the incidence of people up, etc.Water pollution worsen water environment quality, the quality of drinking water has generally been declining, endanger people's health, causing premature fetus or deformity, and so on.Serious pollution incident brings not only health problems, but also cause social problems. 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。
