Engineering nanoparticles of Zinc oxide (nZnO) belong to most widely utilized metalbased nanoparticles in electronics and personal care products. Their expected biological effects could be related to particular properties of nanosized particles and/or bioavailability of Zn2+ from these structures. Recently, the study of the effect of nZnO on the march frog Pelophylax ridibundus detected bioavailability of Zn from nZnO that was not accompanied by increased cytotoxicity in the exposure to nZnO per se. However, the combine exposure to nZnO and elevated temperature oppressed this bioavailability in frog (Falfushynska et al., 2017; Myhalska et al., 2016). Freshwater bivalve mollusks are expected to be particularly at risk from pollution by nZnO because they are sessile and filter large amounts of surface water, including suspended particles. The specimens inhabiting the cooling reservoirs of fuel power plants are subjecting constant combine influence of elevated temperature and industrial pollution. The aim of this study was to elucidate the ability of bivalve mollusks from these reservoirs subjected to combine adverse effects to decompose nZnO at two different temperature regimes depending on their life history in the native habitat.
