TL;DR: Atrazine followed by simazine and 2,4,6-trichlorophenol were the most ubiquitous compounds detected in this area and the present methodology has also been used for searching for new analytes not included in the EC 76/464 list, like Irgarol, DEA and DIA.

TL;DR: Complete removal of estrogenic activity was only obtained at pH 3.3 in this work, and the formation of 2-hydroxyestradiol at pHs 7 and 11 is contributing to the residual estrogenicity of samples ozonized at these pHs.

TL;DR: A novel series of tricyclic ring-C monoaromatic terpanes and a minor group of tricycleclic diaromatic tricyclic terpane compounds were characterized in Tasmanian tasmanite as discussed by the authors.

TL;DR: Atmospheric particulate matter and volatile organic compounds (VOCs) from three sites surrounding a thermoelectric complex, VOCs from the power plant stack gas and aliphatic and aromatic fractions obtained from a coal sample utilized by the thermal unit of a coal-based power plant were monitored in Tubarao and Capivari de Baixo cities, State of Santa Catarina, Brazil in December 1997 as discussed by the authors.

TL;DR: The analytical methodology developed is based on solid phase extraction followed by liquid chromatography tandem mass spectrometry and has been applied to study the occurrence of the above mentioned analytes in environmental waters from the state of Rio de Janeiro (Brazil), showing overall good performance with recoveries above 80%, good linearity and reproducibility.
