摘要：

The PCDD/F levels in the sewage sludge of a village in North-East Germany were substantially above the limit of 100 pg I-TEq/g for sludge applied to land. A study was initiated to identify the PCDD/F sources in the sewage of this treatment plant. It was found that the PCDD/F contamination entered the plant through the faecal inlet, where the content of faecal storage tanks was emptied into the treatment plant. The isomeric patterns of the higher chlorinated homologues were similar to that of PCP, while incineration showed some influence on the lower chlorinated homologues. Cluster analysis revealed a profile similar to that of PCP. (C) 2001 Elsevier Science Ltd. All rights reserved.
