| Абстракт | Most current studies on the toxicity of zinc oxide nanoparticles (ZnO NPs) are conducted under laboratory conditions on single species and do not account for the natural seasonal dynamics of marine ecosystems, creating a gap in understanding the real environmental risks. This study presents the first comprehensive field investigation aimed at establishing the relationships between the seasonal dynamics of abiotic and biotic factors, the composition of the phytoplankton community, and the sensitivity of pelagic phytoplankton to the toxic effects of ZnO NPs in the coastal zone of the Black Sea (Sevastopol Bay). The research was based on the analysis of three size fractions collected monthly throughout 2024–2025: micro-nanoplankton (MNP), picoeukaryotes (PE), and cyanobacteria Synechococcus spp. (Syn). Sensitivity to ZnO NPs was quantitatively assessed using the half-maximal effective concentration (EC₅₀) derived from dose-response curves for the abundance of each fraction. The results revealed significant variability in tolerance both between size groups and throughout the annual cycle. The EC₅₀ value ranges were: 17–89 µg L⁻¹ for MNP, 12–51 µg L⁻¹ for PE, and 10–111 µg L⁻¹ for Syn. Key seasonal EC₅₀ trends showed that the pico-fraction was generally the most sensitive to the toxicant compared to the larger-celled MNP community, supporting the thesis of the heightened vulnerability of small-sized forms. Statistical analysis demonstrated that seasonal changes in phytoplankton sensitivity were closely correlated with fluctuations in community structure and density, as well as with nutrient concentrations. It was found that EC₅₀ variability was significantly associated with the abundance of representatives from the classes Bacillariophyceae, Dinophyceae, and Prymnesiophyceae during their periods of dominance, indicating that species composition is a key factor modulating the ecosystem's response to ZnO NP-induced stress. Furthermore, a significant negative correlation was identified between phytoplankton tolerance and the nitrogen-to-phosphorus ratio (N/P) in the environment. A decrease in this ratio, which is an indicator of nitrogen limitation, was accompanied by increased sensitivity to ZnO NPs. Thus, during periods when phytoplankton experience nutrient stress caused by an imbalance of nutrients, the toxic effect of zinc oxide nanoparticles can be significantly potentiated.
