Chapter 1 Introduction
Section 2 Soil Pollution
一. Soil Pollution
When the concentration of pollutants in the soil environment is more than the soil self-purification capacity, or when the accumulation of pollutants in the soil exceeds the soil environment benchmarks / standards. That is called soil pollution.

Soil Science
Definition of Environmental Soil Science
The disciplinary concept was put forward in the early 1980s.
　　　 Environmental soil science is a subject which researches changes, effects and regulation of soil environmental quality under the natural factors and man-made conditions. Its study subject is soil. It mainly focuses on the protection, utilization and improvement of soil quality. It researches the coordination between soil and the environment, and the sustainable use of soil.
