摘要
Polycyclic musks (HHCB, AHTN, ADBI, AHDI, ATII) and a metabolite of HHCB (HHCB-lactone) were analyzed in sewage sludge samples within the framework of a monitoring network in Switzerland. Mean values in stabilised sludge from 16 wastewater treatment plants were 20.3 mg/kg d.m for HHCB, 7.3 mg/kg d.m for AHTN and 1.8 mg/kg d.m for HHCB-lactone, respectively. Contents of ADBI, AHDI and ATII were between 0.1 and 1.8 ug/kgd.m.(ug = microgram). The results show that polycyclic musks origin mainly from private households and that loads from craft industry, industry and atmospheric deposition are negligible. The technology of wastewater treatment and sludge processing seems to be of minor importance for degradation processes of polycyclic musks. The calculated input in wastewater of polycyclic musks is lower by a factor of 5-7 than the estimates based on use volumes. This discrepancy might be explained by degradation processes, other emission pathways than wastewater or inappropriate estimation of production volumes. (C) 2003 Elsevier Ltd. All rights reserved.
