Environmental pollution overview
Because of the negative impact of the highly developed industries, it is not enough to prevent the adverse effects, which has led to the three major global crises: shortage of resources, environmental pollution and ecological destruction. Human beings are constantly discharging pollutants to the environment. But because of atmosphere, water, soil, such as diffusion, dilution, redox, biodegradation and so on. The concentration and toxicity of pollutants can be reduced naturally. This phenomenon is called environmental self purification. If the discharged material exceeds the self purification capacity of the
environment, the quality of the environment will suffer adverse changes, endanger human health and survival, which has led to environmental pollution.
Aording to environmental factors: air pollution, water pollution, soil pollution.
Aording to human activities: industrial environmental pollution, urban environmental pollution, agricultural environmental pollution.
Aording to the nature and source of environmental pollution, chemical pollution, biological pollution, physical pollution (noise pollution, radioactivity and electromagic wave), solid waste pollution and energy pollution are the main sources of environmental pollution.
Environmental pollution will cause direct damage to the ecosystem and impact, such as desertification, forest destruction, will also cause indirect harm to the ecosystem and human society, sometimes directly harm this kind of indirectenvironment effect than that caused by the larger, more difficult to eliminate. For example, greenhouse effects, acid rain, and ozone depletion are environmental effects derived from atmospheric pollution. The environmental effects derived from environmental pollution are lagging behind, and are often not easily detected or anticipated at the time when pollution ours. However, once it happens, it indicates that environmental pollution has
developed to a rather serious level. Of course, the most direct and easily felt result of environmental pollution is the reduction of the quality of human environment, the quality of human life, health and production activities. For example, the city's air pollution caused by air pollution, increased incidence of people and so on; water pollution to water quality deterioration of drinking water quality general decline, a threat to human health, cause abortion or malformation etc.. Serious pollution incidents not only bring about health problems, but also cause social problems. With the aggravation of pollution and the improvement of people's environmental awareness, the disputes and conflicts caused by pollution have increased year by year.
At present, environmental pollution has appeared in varying degrees worldwide. The aspects of global
influence include air pollution, marine pollution and urban environmental problems. With the globalization of economy and trade, environmental pollution is being more and more internationalized. In recent years, the problem of transboundary movement of hazardous wastes has been highlighted.
