چکیده
This study examined the effects of waterlogging and forest litter introduced to soil on chemical properties pore water ecotoxicity soils highly enriched in As. These were a 21-day incubation experiment. Tested samples collected from Złoty Stok, historical centre arsenic gold mining: forested part Orchid Dump (19,600 mg/kg As) less contaminated site situated neighboring (2020 As). An unpolluted was used as control. The concentrations As, Fe Mn measured together with redox potential Eh. A battery ecotoxicological tests, including bioassay luminescence bacteria Vibrio fischeri (Microtox) several tests crustaceans (Rapidtox, Thamnotox Ostracodtox tests), assess ecotoxicity. bioassays (T. platyurus, H. incongruens) more sensitive than bacterial test Microtox. confirmed that input into may significantly increase toxicity.
