In the present study, the authors demonstrate
the accumulation of heavy metals in water and soft tissues
of bivalve mollusks (Dreissena polymorpha, Dreissena
bugensis) in the Kakhovka Main Canal within the
Kherson and Zaporizhzhia regions (Ukraine) in the
summer season (July–August 2018). The average metal
concentrations in water decrease in the following order:
Ni>Zn>Cr>Co>Cu>Cd. On the whole, the accumulation
of metals in soft tissues of the investigated bivalve
mollusk species was higher than in the samples of water,
since Dreissena are effective bio-accumulators. The
average metal concentrations in soft tissues decrease in
the following order: Zn>Cr>Ni>Cu>Co>Cd. At the end
of the canal, at the 132nd km (Zaporizhzhia region),
where older individuals prevailed, heavy metals were
accumulated most – 159.04 mg/kg.
