Nonylphenol and other detergent-derived contaminants in digested sludges and lake sediments in Switzerland: monitoring controls and archives for risk reduction measures

Many surface active compounds are high-production-volume chemicals, which are discharged after use into wastewaters and enter the aquatic environment. Here we report on the occurrence of branched tetrapropylene benzene sulphonates, linear alkylbenzene sulphonates, nonylphenol, nonylphenol monoethoxylate and dialkyldimethylammonium chloride in digested sewage sludges and in dated recent sediment cores from lakes in Switzerland. The concentrations of detergent-derived contaminants in digested sludges and lake sediments provide useful monitoring controls and archives for risk reduction measures.
