    Polar anthropogenic organic micropollutants are frequently detected in freshwater and discharged on large scale into marine systems. In this work the results of 153 samples collected from the shorelines of the Baltic Sea (Germany), Northern Adriatic Sea (Italy), Aegean Sea and Dardanelles (Greece & Turkey), San Francisco Bay (USA), Pacific Ocean (USA), Mediterranean Sea (Israel), and Balearic Sea (Spain) are presented. The samples were analyzed for various classes of micropollutants such as pharmaceuticals, corrosion inhibitors, biocides, and stimulants. Caffeine, paraxanthine, theobromine, tolyltriazole, 1H-benzotriazole, and atrazine were detected in >50% of all samples. The detection frequencies of carbamazepine, iopamidol, diuron, sulfamethoxazole, paracetamol, theophylline, and atenolol were between 20% and 32%. As caffeine is linked to untreated wastewater, the widespread occurrence of raw sewage in marine environments and thus potentially elevated nutrient concentrations and risk for the presence of wastewater-related pathogens is remarkable.

    Despite its EU-wide ban in 2004 the triazine herbicide atrazine (ATR) and its transformation products (TPs) are frequently detected in the aqueous environment. In this study, concentrations of ATR, two of its TPs, and terbuthylazine (TERB) are presented and discussed in coastal waters of the Northern Aegean Sea, the Dardanelles, the Baltic Sea (Germany), the Northern Adriatic Sea (Italy), and the coastline close to Barcelona (Spain). The water samples (n = 132) were taken in 2009-2011. Sediment samples (n = 7) were taken from Baltic Sea (Germany) and Thermaikos Gulf (Greece). Maximum ATR concentrations (31-41 ng L-1) were detected in Istanbul and the Dardanelles. A concentration gradient from East to West in the Aegean Sea was observed, indicating ongoing ATR contamination via the Dardanelles. Low concentrations and detection frequencies were observed at the other locations, indicating the success of the prohibition. However, the presence of TERB in the Northern Adriatic Sea raises concern. (C) 2013 Elsevier Ltd. All rights reserved.
