Abstract:
Contamination of wastewater from wastewater treatment plants (WWTP) and their discharge into the emissaries is one of the main environmental problems nowadays, due to micro pollutants that are present in concentrations in the order of ng/L or μg/L. A significant part of these contaminants end up in the environment either not transformed or as metabolites contributing to environmental pollution, with a negative impact on human health and wildlife. Among this type of micro pollutants, Bisphenol A (BPA) is an endocrine disruptor with high estrogenic activity and with increased presence in the environment. Similar to other emerging contaminants, Bisphenol A, well known for its endocrine disruptor properties, may undergo different transformations depending on the environment or the technological treatment processes sometimes producing transformation products or metabolites that can have a different ecotoxicological behaviour and profile. The most common metabolite of BPA is 4-hydroxy-acetophenone. In this study a new LC-MS/MS method was developed and optimized for detection of BPA and BPA metabolite, 4hydroxyacephenone in wastewater samples which, after treatment, are discharged in emissaries.
