In this study, 40 healthy women from Chongqing undergoing parturition were recruited and samples of venous blood, umbilical cord blood, breast milk and urine were collected for analysis of organic pollutants by GC/MS. A total of 292 different organic pollutants were detected, including 156 in venous blood, 139 in umbilical cord blood, 176 in breast milk and 138 in urine. Nine different PAEs were detectable in the samples: di-n-butyl phthalate (DBP), bis(2-methylpropyl) phthalate, butyl-8-methyl-nonyl phthalate, di-ethyl phthalate, butyl-2-methylpropyl phthalate, butyloctyl phthalate, di-dodecyl phthalate, di-isodecyl phthalate, and di-tridecyl phthalate. DBP was one of the chemicals detected at the highest frequency (48.82%). DBP concentrations were 84.75+/-33.52, 52.23+/-32.50, 57.78+/-35.42 and 24.93+/-18.67 microg/l in venous blood, umbilical cord blood, breast milk and urine, respectively. This study represents the first investigation of organic pollutants in a Chongqing population.
