Effects and ecological risk assessment of short chain chlorinated paraffins in soil.

Original language description

Short-chain chlorinated paraffins (SCCPs) are industrial chemicals that enter the soil in high amounts (especially in sewage sludge) and then behave as typical persistent organic pollutants in soil ecosystem. Even SCCPs were studied for mammalian and aquatic toxicity, there are no data about their possible effects in soil. In our study, effects on several soil organisms were measured in order to fulfill these gaps in the ecotoxicological profile as was called in ECB Risk Assessment Report for SCCPs. Effects of model chlorinated paraffin C12, 64% Cl were tested on several soil invertebrates and microbial biomass of natural soil. The tested concentrations were 100, 320, 1000, 3200, and 10000 mg/kg. No mortality was recorded for Eisenia fetida and Enchytraeus crypticus at tested concentrations. Only small mortality (10-30%) was recorded for Folsomia candida at the highest concentration tested. The lowest statistically significant NOEC for reproduction of all species was 1000 mg/kg.
