Severe Toxic Effects on Pelagic Copepods from Maritime Exhaust Gas Scrubber Effluents
P Thor, Maria Granberg, Hulda Winnes, Kerstin Magnusson
Abstract
, respectively, and compared to previous studies on oil toxicity in copepods, scrubber effluents appear more toxic than, for example, crude oil. None of the individual PAHs or heavy metals analyzed in the effluents occurred in concentrations which could explain the high toxicity. The effluents showed unexpected alkylated PAH profiles, and we hypothesize that scrubbers act as witch's cauldrons where undesired toxic compounds form so that the high toxicity stems from compounds we know very little about.
