Abstract The concentrations of 7selected pharmaceuticals and personal care products (PPCPs) in the leachate samples from a landfill site of municipal solid waste in Shanghai were determined by solid phase extraction and high liquid chromatography-electrospray tandem mass spectrometry. Besides, the removal efficiencies of the leachate treatment processes for the target PPCPs were investigated. The developed analytical method showed acceptable recoveries (89%~173%), relative standard deviation (<20%) and limits of quantification (0.025~1.0μg/L), meeting the requirement for detecting environmental samples. The results showed that the target PPCPs ranged from below limit of quantification (90%, respectively, and the total removal efficiencies were above 97%. The concentrations of target PPCPs in the final effluent were from
