TL;DR: The toxic potential of coplanar polychlorinated biphenyls (PCBs), expressed by their toxic equivalent (TEQ) values according to Safe and to the recent WHO/ICPS recommendations, was determined in blue mussel samples collected at six sites in the Weser, Jade, and Elbe river estuaries during the spring and the autumn period.

TL;DR: In this article, an estimation of the annual balances of these compounds was accessible that allowed the following conclusions: a loss of 2 t yr−1 HCH between input into and output out of the German Bight has to be stated, while more α-HCH is leaving this area at its northern boundary.

TL;DR: Seasonal variations in the organochlorine content and PCB patterns of female dab ovary and liver are influenced by the reproduction cycle of the fish.

TL;DR: The presence of PCBs in almost every part of the global ecosystem, including polar regions, has been demonstrated in many subsequent analytical studies as mentioned in this paper, and the potential for bioaccumulation has been identified.

TL;DR: In this paper, the phase distribution of contaminants is studied and the affinity of the numerous contaminants to different phases - dissolved, coloids, particles and organisms of different quality, sediment and aerosols - is variable due to environmental conditions (pH, oxygen) and will change when the contaminants are modified by chemical reactions (speciation, conversion).
