Characterization of organic pollutants in landfill leachate and groundwater around MSW using GC-MS with SPE

摘要

Characteristics of organic pollution in landfill leachate and groundwater around municipal solid waste (MSW) was investigated in landfill leachate of JinKou sanitary landfill site by chromatograph/mass spectroscopy (GC/MS) with Solid-phase extraction (SPE). 138 kinds of main organic pollutants were identified. Landfill leachate has become a major source for organic pollution of the aquatic environment, including surface water, perched water, phreatic water and confined groundwater. The more distance from landfill site, the less organic pollutants in samples. 8 kinds of organic compounds were detected in groundwater samples. Special concern should be paid to N-Ethyl-4-methoxy-alpha-methylphenethylamine and Dibutyl phthalate in the aquatic environment around MSW.
