We measured Dechlorane Plus (DP) and its dechlorinated analogs in the blood and milk from women living in e-waste recycling sites in Wenling of Taizhou region, China (n = 49). Both syn-DP and anti-DP were detected in all samples. Another compound, Cl11-DP, was detected in 45% and 84% of milk and serum samples, respectively. DP levels in blood and milk from residents living in the local environment >20 yrs (R20 group) were significantly higher than those living in Taizhou <3 yrs (R3 group) (p < 0.05). The milk/serum partition coefficient from the same women was approximately 0.43 and 0.47 for syn-DP and anti-DP, respectively. A similar value in milk compared with anti-DP/∑DPs (fanti) in serum suggested that stereoselective DP bio-accumulation did not occur during the DP transport from blood to milk. This result indicate that DP can bio-accumulate in blood and milk with the low milk/serum partition coefficient and similar blood and milk stereoselective bio-accumulation profiles.
► Our study observed that DP and Cl11-DP can bioaccumulate in maternal blood and milk.
► A stable partitioning of DP between milk and serum was observed.
► Stereoselective DP accumulation did not occur during DP transport from blood to milk.
► Exposure from e-waste recycling was a dominant factor affecting the DP level.
