The activities of smelters are often responsible for emitting pollution, especially PTEs, which are known to have a negative impact on the environment. Hence, the areas with active or past smelter activities are now of great concern. Following this idea, the analysis of the soil samples from the area nearby post-metallurgic waste dump, which is a remnant of the smelter where ferrochrome was produced, was performed. The samples were analyzed in terms of metal concentrations (Zn, Cu, Pb, Fe, Cr) and only the concentrations of Pb did not exceed the limit value for soil. Calculations of the exposure doses for each of these metals were also presented, considering different routes of exposure. Additionally, Hazard Quotient (HQ), Hazard Index (HI), and excessive risk of cancer development (ECR) were calculated, which helped to estimate the health risk.

Assessment of the "Oława" Smelter (Oława, Southwest Poland) on the Environment with Ecotoxicological Tests

The aim of the research was to study the impact of "Oława" smelter on surroundings. For this purpose, water, soil and sediments were collected in the vicinity of smelter and subjected to selected ecotoxicological tests. The authors used Spirodela polyrhiza duckweed and Brachinious calyciflorus rotifer for the assessment of the water from Odra River, and Heterocypris inconqruens ostracod for the sediment studies. Triticum sativum and Avena sativa monocotyledons as well as Sinapis alba and Lepidium sativum dicotyledonous plants were used to perform the soil toxicity tests. The obtained results proved slight sediment toxicity, but no toxicity of water was observed. The inhibition of root growth of tested plants was observed suggesting the impact of toxicity on soil. The studies proved that only the area in the nearest vicinity of the "Oława" smelter is still contaminated with heavy metals and may pose a serious threat to the environment.
