Produced water collected from oil and gas platforms on the United Kingdom Continental Shelf was characterized for nonregulated pollutants through an effects-directed analysis procedure. Produced water samples were characterized for the presence of aryl hydrocarbon receptor (AhR) and estrogen receptor (ER) agonists using the dioxin-responsive, chemical-activated luciferase gene expression assay (DR-CALUX) and yeast estrogen screen (YES) bioassays. The AhR and ER agonists were then isolated by normal-phase, high-performance liquid chromatography and identified using gas chromatography coupled to mass spectrometry in a number of formats. The identified compounds were cross-referenced with those compounds routinely analyzed and regarded by the Oslo and Paris (OSPAR) Commission for the North East Atlantic as priority hazardous substances. The occurrence in produced water of a number of nonregulated compounds with demonstrable potential environmental effects is presented, to our knowledge for the first time. These include persistent organic contaminants, such as hexachlorobenzene, decachlorobiphenyl, and octachlorodibenzofuran.
