The geological environment provides living space and habitat for living things, and the water, air and nutrients needed by living things can be obtained here. The soil environment, on the other hand, provides food and nutrients directly to most organisms. With the continuous improvement of the level of urbanization, the population is concentrated in cities on a large scale, and the development of economy, society and science and technology is getting faster and faster. However, the environmental pollution problem brought by urbanization is becoming more and more prominent. The expansion of urban scale and the discharge of various pollutants caused by urbanization make soil pollution bear the brunt.
