Bioconcentration of PCBs in the pelagic food chain of the Ross Sea
Listed in NASA Earthdata CMR
In this study was measured mean PCB concentration (the sum of 50 congeners) in Ross Sea phytoplankton (mainly diatoms) and mixed zooplankton (copepods, amphipods and krill) of 1 and 4.2 ng g–1 wet wt. respectively.
Description
Although the percentage of each congener was a small percentage of the total PCB content (<10 %) in seawater, phytoplankton showed a remarkable increase in PCBs 153, 138, 180 and 195.
