Soil environmental monitoring refers to determining the environmental quality (or pollution degree) and its changing trend by measuring the representative values of factors that affect the soil environmental quality. Generally speaking, soil monitoring refers to soil environmental monitoring, which can be generally divided into regional soil background, farmland soil environment, soil environmental assessment of construction projects, soil pollution accidents and other types of monitoring, including site sampling, sample preparation, analysis methods, and characterization of results , Technical statistics such as data statistics and quality evaluation.

Soil pollution can be roughly divided into inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, strontium compounds, compounds containing arsenic, selenium, fluorine, etc.; organic pollutants mainly include organic pesticides, phenols, cyanide, petroleum, synthetic detergents, urban sewage , Harmful microorganisms brought by sludge and manure.
