摘要：

The heavy metal concentration in sewage sludge is one of the most important factors affecting sewage sludge use. During the last 20 years there has been a constant decline in the heavy metals concentration. Occasional point discharges and diffuse sources are now the main sources for heavy metals in sludge. in 1996-97 and in 2001-02 similar surveys of organic micropollutants in Norwegian sewage sludge have been performed. Monthly composite samples from 7 WWTPs have been analysed for PCDD/PCDF, PCB (7), PAH (16), NPE, DBP, DEHP and LAS. The two studies have used the same methods in the same months and at the same treatment plants. The results show a decline of between 23 and 92 % of different organic micropollutants in Norwegian sludge from 1996-97 to 2001-02.
