环境污染特征

Here have five characteristics can be summarized as follows:

1.Spatial distribution 空间分布性

Into the environment of pollutants and pollution factors, along with the flow of water and air diluted spread. The stability of different pollutants and pollution and the nature of the diffusion rate, and therefore, different spatial locations contaminant concentration and intensity distribution is different.污染物和污染因素进入环境后，随着水和空气的流动而被稀释扩散。不同污染物的稳定性和扩散速度与污染性质有关，因此，不同空间位置上污染物的浓度和强度分布是不同的。

2.Time distribution 时间分布性

The emission of pollutants and pollution factors, intensity changes with time.污染物的排放量和污染因素的强度随时间而变化。For example, industrial emissions and the type and concentration of pollutants tend to change over time. Since tidal rivers and wet period, alternating dry season, will make pollutant concentration varies with time. 例如，工厂排放污染物的种类和浓度往往随时间而变化。由于河流的潮汛和丰水期、枯水期的交替，都会使污染物浓度随时间而变化。

3.persistence长久性

many long-term continuous impact pollution, endangering people's health and life, is not easy to eliminate. 许多污染长期连续不断的影响，危害人们的健康和生命，并不易消除。

4.pollution公害性

Environmental pollution from regional, ethnic, economic conditions, all suffer.环境污染不受地区，种族，经济条件的影响，一律受害。

tency潜伏性

Much pollution is not easy to discover, once the outbreak of serious consequences.许多污染不易及时发现，一旦爆发后果严重。
