在一年的时间内，在流入和流出的废水和在初级，二级和消化污泥中的十六种药物活性化合物的发生进行了评估。固体-水分配系数（Kd）的计算，以评估这些化合物从废水中的吸附到污泥上的去除效率。此外，还评估了废水排入受纳河流和将消化污泥作为肥料施于土壤对水生和陆地生态系统造成的生态毒理学风险。在废水中检测到12种药物，平均浓度为0.1至32 μ g/L。废水中发现的所有化合物也在污水污泥中发现，但双氯芬酸除外，平均浓度为8.1至2206 μ g/kg dm。依维柯、水杨酸、吉非贝齐和咖啡因是浓度最高的化合物。Log K-d值在1.17（萘普生）和3.48（卡马西平）之间。流出废水和消化污泥中最高的生态毒理学风险是由于布洛芬（风险商数（RQ）：分别为3.2和4.4），17 α-乙炔基雌二醇（RQ：分别为12和22）和17 β-雌二醇（RQ：分别为12和359）。废水排放和污泥处置后的生态毒理学风险仅限于消化污泥改良土壤中存在的17 β-雌二醇（RQ：2.7）。(C)2012爱思唯尔有限公司版权所有。
The occurrence of sixteen pharmaceutically active compounds in influent and effluent wastewater and in primary, secondary and digested sludge in one-year period has been evaluated. Solid-water partition coefficients (K-d) were calculated to evaluate the efficiency of removal of these compounds from wastewater by sorption onto sludge. The ecotoxicological risk to aquatic and terrestrial ecosystems, due to wastewater discharges to the receiving streams and to the application of digested sludge as fertilizer onto soils, was also evaluated. Twelve of the pharmaceuticals were detected in wastewater at mean concentrations from 0.1 to 32 mu g/L All the compounds found in wastewater were also found in sewage sludge, except diclofenac, at mean concentrations from 8.1 to 2206 mu g/kg dm. Ibuprofen, salicylic acid, gemfibrozil and caffeine were the compounds at the highest concentrations. Log K-d values were between 1.17 (naproxen) and 3.48 (carbamazepine). The highest ecotoxicological risk in effluent wastewater and digested sludge is due to ibuprofen (risk quotient (RQ): 3.2 and 4.4, respectively), 17 alpha-ethinylestradiol (RQ: 12 and 22, respectively) and 17 beta-estradiol (RQ: 12 and 359, respectively). Ecotoxicological risk after wastewater discharge and sludge disposal is limited to the presence of 17 beta-estradiol in digested-sludge amended soil (RQ: 2.7). (C) 2012 Elsevier B.V.
