Distribution characteristics and risk analysis of DDTs in soils of the Yellow River Delta
Abstract：Bincheng District is in the Binzhou City, located at the center of the Yellow River Delta YRD. To assess the current status of soil dichlorodiphenyl trichloroethane （DDT） residues and distribution characteristics, topsoil samples （0--20 era） were collected in this area. Concentrations of six soil DDT homologues （ρ,ρ′-DDT,σ,ρ′-DDT,ρ,ρ′-DDE,σ,ρ′-DDD,ρ,ρ′-DDD） ranged from 63.81 to 315.65 g/kg, with an average concentration of 190.52 g/kg, showing significant increase along the urban--rural gradient. Soil DDTs originated mainly from the past DDT usage and dicfol appliealion. According 1o the guidelines of the Chinese Environmental Quality Standard for Soils, soil DDTs residues were classified as low pollution. Monitoring and remediation is advised to assess and reduce negative environmental and human health effects from soil DDTs in the study area.
