Abstract
Soil, as an important component of the earth, is the basis for all creatures’ existence. Soil is a dynamic and developing system that can be changed by human activities. In contrast to the atmospheric and water environment, environmental pollutants can accumulate and store in the soil for longer time. This chapter first introduces the definition of soil and soil sampling methods and then focuses on environmental analysis of various types of representative pollutants and nutrients in the soil, including pesticides, nitrate, nitrite, phosphorus, and heavy metals. Some relevant techniques, concepts, and methods are also described in this chapter, such as QuEChERS, nanopesticide, potentiometry, Griess reaction, common digestion solvents, wet digestion of soil samples, microwave digestion of soil samples, and laser-induced breakdown spectroscopy.
