Strategies for Mitigating Seasonal Heavy Metal Release in River Sediments Using Natural Mineral‐Based Materials

ABSTRACT This study presents an ecological and geochemical assessment of trace element contamination in the Huyva River (Ukraine), a right tributary of the Teteriv River that supplies drinking water to Zhytomyr and nearby settlements. The research involved monitoring key physicochemical parameters, including pH, mineralization, hardness, and major ion composition, to evaluate seasonal and spatial hydrochemical variations. Concentrations of trace elements in water and bottom sediments were analyzed for 2014 and 2024, covering Ba, Pb, Ti, Mn, Cr, Ni, V, Cu, Ag, Li, Cd, Co, and Zn. Pollution was quantified using Contamination Factor (CF), Contamination Degree (CD), Overall Pollution Index (Zc), and Geo‐accumulation Index (I geo ). The results revealed an increase in Mn, Cu, Pb, and Co levels in sediments and a general rise in overall pollution, attributed to anthropogenic activities, hydrological alterations, and climatic factors—notably higher temperatures and lower oxygen levels that enhance metal mobility. The study also evaluated potential stabilization strategies for heavy metals, including physicochemical, biological, and engineering methods. Among them, natural carbonate materials were identified as the most effective due to their environmental compatibility, affordability, and ability to operate near water intake areas without disturbing water treatment systems, supporting sustainable water quality management.
