Abstract
In this study, we evaluate the ability of fish to accumulate copper when using copper(II) oxide (CuO) nanoparticles as a sanitation agent in bodies of water. For this purpose, we performed chemical–toxicological analysis of fish organs and tissues. The results showed that after treating the body of water with CuO at a concentration of 20 µg/L, copper concentration in fish tissues slightly increased and remained within the normal range. When determining toxicity limits, it was established that higher concentrations of CuO can be used with short-term exposure. The obtained data indicate the possibility of using CuO as a prophylactic agent in aquaculture.
