What is the comprehensive soil pollution index?
What is the comprehensive soil pollution index? The soil pollution index is an environmental quality index that evaluates the comprehensive effects of soil contamination by various pollutants. The superposition of the pollution index of various pollutants in the soil is often used as a comprehensive index of soil pollution.
For example, P = P = where: P is the soil pollution index; Pi is the pollution index of pollutant I; n is the number of pollutants; Wi is the weight of pollutant I. The latter reflects the different effects of various pollutants. According to the size of P value, it can reflect the extent of soil contamination. At present, some people use the abstract value of P value for soil pollution grading, which often lacks the effect basis and has no practical value.
