Bivalves and gastropods are the most vulnerable among hydrobionts in radioactively contaminated reservoir

Andrey Peretykin, Svetlana I. Andreeva, Natalia I. Atamanyuk, Alexandr V. Trapeznikov et autres

The response of mollusk communities to radioactive contamination in natural freshwater ecosystems remains understudied. We have analyzed the data on species composition of bivalve and gastropod mollusks inhabiting the «Mayak» Production Association (PA) (Russia, Chelyabinsk Region) special industrial reservoirs (R-3, R-4, R-10, …
