The harm of air pollution
• air pollution and health damage to human body • the atmosphere, the survival and development of biological contamination • the erosion of the atmospheric pollution of objects • the influence of atmospheric pollution on global atmospheric environment Obvious impact on the global atmosphere in three aspects: one is the ozone depletion, the second is the corrosion of acid rain, the third is global warming.
The source of soil pollution
• (1) with the sewage into the soil heavy metal • (2) as the atmospheric precipitation into the soil heavy metal • (3) with the solid wastes into the soil heavy metal • (4) with the agricultural material into the soil heavy metal
The characteristics of soil pollution
• (1) soil pollution has concealment and hysteresis. • (2) the cumulative of soil pollution. • (3) soil pollution is irreversible.
