Is the Slag Heap of a Former Ferrochromium Plant a Significant Environmental Hazard?

This study assessed the possible impact of a former ferrochromium plant in Siechnice (Lower Silesia, Poland) on water reservoirs and living organisms. The metal concentrations (Zn, Cu, Pb, Fe, Cr) sediments were determined, along with ecotoxicological studies that conducted both surface three bodies border slag heap. samples taken at different distances from landfill area. also covered human health risk assessment. highest all studied elements observed reservoir closest to landfill. In case sediments, 30% death rate for Heterocypris incongruens (Ostracodtoxkit F) was recorded same site. Additionally, this site, revealed mortality Daphnia magna (Daphtoxkit F magna) lowest values LC50 algae (Algaltoxkit). assessment estimated by calculating noncarcinogenic using hazard quotient (HQ) index (HI), carcinogenic calculated excessive cancer development (ECR) measurement. (HIing) Cr exceeded 1 children, which suggests adverse effects might occur humans. ECR Pb above range limit 10−6. value children adults. Studies prove located near landfills pose potential ecological risks, is where distance shortest prospective assessments, body humans, especially fish consumers, i.e., residents neighboring areas who experience severe problems intake through consumption. Significant steps should be reduce minimize effects.
