- Integrated monitoring of 10 anticancer drugs in wastewater effluents and surface water.
- Tamoxifen, ciprofloxacine, cyclophosphamide and methotrexate were the most frequently detected compounds.
- Tamoxifen and cyclophosphamide passed unaltered through wastewater treatment plant.
- Tamoxifen and ciprofloxacine are likely to be of environmental concern because of their ecotoxicity, and ubiquity.
The presence of 10 anticancer drugs was studied along the entire urban water cycle -from hospital effluents through urban wastewater treatment plant till surface waters- and their potential environmental risk was assessed. Azathioprine, etoposide, docetaxel, paclitaxel, methotrexate, cyclophosphamide, tamoxifen and ciprofloxacin were detected in hospital effluent and in the urban influent of the sewage treatment plant although most of them were totally eliminated after WWTP. Only cyclophosphamide, tamoxifen and ciprofloxacin were found in both WWTP effluent and in the receiving river at a concentration range between nd-20 ng Lâ1, 25-38 ng Lâ1 and 7-103 ng Lâ1 respectively. Tamoxifen and ciprofloxacin, commonly used for veterinary practices, were also detected in the river upstream the sewage discharge. In addition, they both were considered to pose a potential risk to the environment based on the levels found in the WWTP effluent together with their ecotoxicological impact in selected organisms.
