Environmental monitoring is to use chemical, physical, biological, medical, telemetry, remote sensing, computer and other modern scientific and technological means to monitor, measure, various environmental data and trends, so as to make a comprehensive assessment of environmental quality. It contains the following part:

Water quality monitoring: It is divided into water environment quality monitoring and wastewater monitoring. Water environment quality monitoring includes surface water and groundwater. Monitoring items include physical and chemical pollution indicators and related biological indicators, and also include hydrological parameters such as flow rates and flow rates.

Air detection: Divided into air environment quality monitoring and pollution source monitoring. Air monitoring often requires meteorological parameters such as wind direction, wind speed, air temperature, air pressure, and humidity.

Soil monitoring: The key monitoring items are heavy metal elements, harmful non-metallic elements and residual organic pesticides that affect the soil ecological balance.

Solid waste monitoring: Including industrial wastes, wastes from health care institutions, agricultural wastes, radioactive solid wastes, and municipal solid waste. The main monitoring items are the hazardous characteristics of the solid waste and the characteristics of the household waste. It also includes the determination of the composition and content of toxic and hazardous substances and toxicological experiments.

Biological monitoring and biological pollution monitoring: Biological monitoring is the use of biological monitoring of environmental pollution. Bio-contamination monitoring is the use of various detection methods to monitor toxic and hazardous substances in living organisms. The monitoring items are mainly heavy metal elements, harmful non-metallic elements, pesticide residues and other toxic compounds.

Ecological monitoring: Observing and evaluating the response of ecosystems to natural and human-induced changes is a measure of the spatial-temporal pattern of the structure and function of various ecosystems, focusing on changes in biological communities and populations.

Physical pollution monitoring: refers to the physical factors that cause environmental pollution such as noise, vibration, electromagnetic radiation, radioactivity and other monitoring.
