Abstract
This study presents a complementary approach for the evaluation of water quality in a river basin by employing active and passive sampling Thirtyeight hydrophilic organic compounds HpOCs organohalogen herbicides organophosphorous pesticides carbamate triazine urea pharmaceuticals phenols and industrial chemicals were studied in grab water samples and in passive samplers POCIS collected along Strymonas River Northern Greece at three sampling campaigns during the year 2013 Almost all the target compounds were detected at the periods of high Rainfall Intensity and/or low flow rate The most frequently detected compounds were aminocarb carbaryl chlorfenviphos chloropropham 24D diflubenzuron diuron isoproturon metolachlor and salicylic acid Bisphenol A and nonylphenol were also occasionally detected The use of POCIS allowed the detection of more micropollutants than active sampling Low discrepancy between the concentrations obtained from both samplings was observed at least for compounds with 50 detection frequency thus POCIS could be a valuable tool for the selection and monitoring of the most relevant HpOCs in the river basin Results showed relatively low risk from the presence of HpOCs however the potential risk associated with micropollutants such as carbaryl dinoseb diuron fenthion isoproturon metolachlor nonylphenol and salicylic acid should not be neglected
