This investigation reveals trace element accumulation in zooplankton of different sizes, suggesting environmental impacts.
Within the framework of the program “Marine Ecosystems of the Siberian Arctic”, bioaccumulation of heavy metals and arsenic by zooplankton organisms of different size fractions in two areas of the Kara Sea (the north-eastern part and the Blagopoluchie Bay) was investigated. For the first time, near the southern edge of the Severnaya Zemlya ice sheet, concentrations of eleven trace elements were determined in the sized fractions of the most abundant group of copepods Calanus spp. The highest concentrations of Fe, Mn, Co, Ni, V, Cu, Pb, Zn and Cd were found in small fraction (0.5–1 mm) compared to the middle (1–5 mm) and coarse (>5 mm) ones. A spatial distribution of trace elements in copepods, amphipods, euphausiids, and pteropods along transects in both areas was considered. The environmental factors, the totality of which can indirectly affect the bioaccumulation of trace elements, were assessed.
