Study on the PCOPs in shallow groundwater around landfill sites based on comprehensive scoring method
The study of organic pollutants has become critical for pollution prevention and control in shallow groundwater around landfills.Currently,there were typical challenges,including poor in research,difficulty in detecting,and obstacle in identifying accurately,making the screening of PCOPs particularly important.Based on the concept of"source-path-receptor",an ITD model was constructed using a comprehensive scoring method,taking the shallow groundwater around landfills in a major city in the Yangtze River Delta as the research object.The comprehensive scores of 68 types of organic pollutants in initial list ranged from 49.31 to 167.77.K-means clustering analysis was used to screen out three levels of PCOPs,by which 14 types of HPCOPs,39 types of MPCOPs and 15 types of LPCOPs were screened out.HPCOPs had good consistency with domestic and foreign research inventory,standards,and actual pollution characteristics.Targeted measures were proposed to prevent and control pollution of PCOPs,and recommended that HPCOPs could be listed in the"inventory of shallow groundwater PCOPs around landfills".The research results provided new ideas for the screening of PCOPs in landfills and theoretical basis for the pollution prevention and control of shallow groundwater around landfills.
