摘要

To evaluate the contaminated conditions of benzo[a]pyrene (B[a]P) and phenanthrene (PA) in sludge and to ascertain whether B[a]P limit for land application of sludge exists,the contents of B[a]P and PA in 46 sludge samples from 15 cities in the Yangtze River Delta area of China were determined using high performance liquid chromatography (HPLC) coupled with a fluorescence detector after ultrasonic extraction and silica gel clcanup.B[a]P contents ranged from non-detectable to 1.693 mg kg-1 dry weight (DW),averaged 0.402 mg kg-1 DW,and were ＜ 1.0 mg kg-1 DW in most of the sludge samples.PA was found in all the sludge samples analyzed;its contents ranged between 0.028 and 1.355 mg kg-1 DW,with an average value of 0.298 mg kg-1 DW.Most of the sludge samples contained ＜ 0.5 mg kg-1 DW PA.All 46 municipal sludge samples analyzed in this study showed B[a]P contents ＜ 3.0 mg kg-1 DW,which is the limit value for sludge applied to agricultural lands in China.The contents and distributions of B[a]P and PA in municipal sludge were related to sludge types,sources and treatment technologies,along with the physical and chemical properties of these pollutants.
