An assessment of lithiums ecotoxicity in soils with varying characteristics was conducted using three soil types: Haplic Chernozem, Eutric Cambisol, and Eutric Arenosol. Different lithium concentrations were applied to simulate contamination. The study examined changes in enzyme activity, bacterial counts, phytotoxic properties, and calculated an integrated indicator of soil biological state. Results indicate that lithium contamination reduces soil biological parameters, with the degree of reduction depending on soil type and lithium concentration. Haplic Chernozem demonstrated the highest resilience against lithium contamination due to its high humus content and heavy granulometry. Findings are crucial for establishing safe lithium levels in soils and forecasting ecological risks.
