TL;DR: Among the organochlorines analyzed, DDTs were predominant, followed in decreasing order by PCBs, CHLs, TCPMe, TCPMOH, HCHs, and HCB, which suggested that the sources of exposure of harbor seals to organochchlorines were different from those in the other two species.

TL;DR: Investigation of human breast milk from women living near dumping sites of municipal waste and reference sites in India, Cambodia, Vietnam, and the Philippines during 1999 to 2000 finds that mothers who have been exposed to relatively high levels of DRCs transfer greater amounts of these contaminants to the first infant than later ones through breast-feeding, which implies that the first children of these mothers might be at higher risk from DRAs.

TL;DR: The present study elucidated the biomagnification profiles of persistent organic pollutants (POPs) through a tropical aquatic food web of Vietnam based on trophic characterization using stable nitrogen analysis and reported the first reports of TCPMe and DDTs, which are reported for the first time.

Organochlorine and organotin compounds in Caspian seals (Phoca caspica) collected during an unusual mortality event in the Caspian Sea in 2000.

TL;DR: Although compositions of organochlorine pesticides in seals suggested that the contamination status in the Caspian Sea is improving, the levels found in Caspia seals in 2000 were comparable to those in other marine mammals that have suffered from epizootics, implying that the present status of contamination found inCaspian seals poses a risk of immunosuppression.

Organochlorine contamination in fish and mussels from Cambodia and other Asian countries
TL;DR: Contamination by organochlorine compounds (OCs) was examined in fish and mussels collected from Cambodia and other Asian developing countries in 1997 and 1998 as discussed by the authors, and it was concluded that Cambodia is one of the countries least contaminated by OCs.
