Abstract
A comprehensive investigation into the occurrence of Dechlorane Plus (DP) in environmental samples around a DP manufacturing plant in East China was performed. The total syn-DP and anti-DP concentrations found in the soil, sediment, active air, and passive air samples were 0.50-2,315Â pg/g dry weight (dw), 0.32-20.5Â ng/g dw, 5.52-3,332Â pg/m3, and 1.00-4,560Â pg/m3, respectively. There were consistent trends in the spatial distributions of DP in the soil and air samples, with the DP concentrations decreasing dramatically as the distance from the plant increased. The mean anti-DP isomer fractional abundances (fanti) in the soil, sediment, active air, and passive air samples were 0.67, 0.68, 0.70, and 0.64, respectively. These fanti values were consistent with the fanti value for the technical DP produced in the DP manufacturing plant (0.68), meaning that the DP had been released during the local DP production activities.
