This invention discloses a method for screening priority pollutants for key industry production sites. The invention uses a screening procedure based on "meta-analysis-multi-risk coupling-multi-objective decision-making" to screen pollutants requiring priority control in key industries. First, a meta-analysis is used to summarize and analyze pollutant studies of the target industries, initially screening out pollutants of high concern. Then, the soil-groundwater environmental chemical behavior analysis of these high-concern pollutants is integrated to calculate the risks to human settlement safety, drinking water safety, and ecological safety. The coupling degree of these three safety risks is calculated using a coupling coordination degree model, and the pollutants are ranked from highest to lowest to form a refined list of pollutants for the target industries. Finally, based on multi-objective decision-making recommendations from multiple parties, a list of pollutants requiring priority control is formed. This invention can more accurately identify priority pollutants in different key industry sites than existing methods, and can carry out scientific prevention and control work more efficiently from the source.
