Spatio-temporal patterns of PAHs, PCBs and HCB in sediments of the western Barents Sea

Spatio-temporal patterns of PAHs, PCBs and HCB in sediments of the western Barents Sea

We examine the composition and levels of organic contaminants (PAHs, PCB, HCB) in four sediment cores collected from the Barents Sea.We assess the influence of temporal variations in contaminant supplies and post-depositional reworking on contaminant distribution. Anthropogeniclevels of ∑12...
