The present work shows the methodology (study of a method) for the analysis of four emerging pollutants. Each studied pollutant represents a family from emerging pollutants (an estrogenic compound, an antibacterial, a pharmaceutical and a fragrance). The method was optimized to be used in a complex environmental matrix such as sediment interstitial water of a wetland with high organic matter content. The extraction of the compounds was carried out by solid phase extraction technique and quantified by gas chromatography with mass spectrometry in single ion monitoring mode. The method was validated using the "Single Laboratory Method Validation Process" through the determination of the performance parameters of the method. The optimized method was applied to the analysis of sediment interstitial water from the canals of the periurban agricultural zone of Xochimilco, Mexico. This preliminary study showed that the sampling point close to the wastewater discharge area from the secondary treatment wastewater plant had the highest concentration of emerging pollutants. Also, an inversely proportional relationship was observed between the concentrations of ibuprofen and musk with the concentration of organic matter in the sediments. The optimization of the method and the ratification with sediment interstitial water samples from the wetland, showed the worthiness of the method for the evaluation of the presence and distribution of emerging pollutants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
