[0002] Soil environmental monitoring refers to an important measure to understand the status of soil environmental quality. With the purpose of preventing and controlling the hazards of soil pollution, it dynamically analyzes and measures the degree of soil pollution and its development trends. It includes surveys on the current status of soil environmental quality, surveys on regional soil environmental background values, investigations on soil pollution accidents, and dynamic observations of contaminated soil. Soil environmental monitoring generally includes steps such as preparation, site layout, sampling, sample preparation, analysis and testing, and evaluation. The sampling step is particularly important. The quality of the samples taken directly affects the subsequent monitoring of the soil.
