Occurrence of pesticides and contaminants of emerging concern in surface waters: Influence of surrounding land use and evaluation of sampling methods. Picogram and IUPAC Congress Program. Vol. 86, p. 102, Abstract No. 481. Available: www.agrodiv.org/picograms.Interpretive Summary:
                                Technical Abstract: Biologically active compounds originating from agricultural, residential, and industrial sources have been detected in surface waters, which have invoked concern of their potential ecological and human health effects. Automated and grab surface water samples, passive water samples - Polar Organic Contaminant Integrative Sampler (POCIS), and sediments were collected from four sub-watersheds of the Zumbro River Watershed, Minnesota, USA. Samples obtained throughout a two-year collection cycle were extracted and analyzed for contaminants of emerging concern (CEC) including pesticides, pharmaceuticals, antibiotics, hormones, phytoestrogens and wastewater contaminants. Evaluation of CEC profiles with land use characteristics, temporal variation of CEC occurrence, and effectivness of different sampling methods were compared to assess the magnitude of impact of agricultural and non-agricultural land use on surface waters and to provide recommendations for monitoring protocols. Understanding the occurrence and sources of these contaminants is important in order to design and implement appropriate reduction and remediation strategies.
