Abstrakt:

Data on heavy metal and other chemical element concentrations in organisms of the amphipod Gmelinoides fasciatus (Stebbing 1899) from the littoral zone of Petrozavodsk Bay, Lake Onego, are reported. The Baikal sub-endemic species G. fasciatus is the only representative of the genus of the Baikal origin. This invader migrated from the Karelian Isthmus lakes to Lake Ladoga, Europe’s largest lake, where it was reported in 1988-1990 to be inhabiting the northern and western littoral zones of the lake. Samples of crustaceans, collected in 2016, were dried and analyzed by inductively coupled mass-spectrometry (ICP MS). Mn, Sr, Zn, Cu, Pb, Cd, Tl, As, V, Cr, Ni, Co, Mo and W accumulation levels in living tissues were assessed. Macro- and trace element accumulation patterns, related to the age and sex of amphipods and the time of sampling from Lake Onego, were revealed. A general sequence of all the elements analyzed is: Sr > Mn > Zn > Cu > Ni > Cr > As > V > Pb > Co > Cd > Mo > W > Tl. It shows that the macroelements Sr, Mn, Zn and Cu are essential for small crustaceans and that the sequence results from the harmful influence of anthropogenic factors on the littoral zone of Lake Onego. Pb, Cd, Mn, V, Cr and Co concentrations in juvenile Baikal amphipods, regardless of a sampling season, markedly exceed those in adults. This is associated with the feeding ration of juvenile crustaceans dominated by detritus, which can accumulate metals. Accumulation of heavy metals in organisms of the amphipod may be associated with the presence of various industries in Petrozavodsk, automobile, railway and river transport and domestic waste, including storm sewage, discharged directly into Lake Onego.
