| Popis | Despite the fact that chlorinated paraffins have been produced in relatively large amounts and their high concentrations were found in sewage sludge applied to soils, poor information on their levels in soils and effects on soil organisms are available. Aim of this study was to gather the new data of chlorinated paraffins toxicity in the soils. Effects of short chain chlorinated paraffins (64% chlorine content) on invertebrates (Eisenia fetida, Folsomia candida, Enchytraeus albidus, Enchytraeus crypticus, Caenorhabditis elegans) and substrate-induced respiration of indigenous microorganisms were studied. Differences in sensitivity of tested organisms to short-chain chlorinated paraffins were found where F. candida showed to be the most sensitive organism with LC50 and EC50 values of 5733 mg/kg and 1230 mg/kg respectively. Toxicity results were compared with available studies and the predicted no effect concentration (PNEC) of 5.28 mg/kg was estimated based on our data for soil environment. |
