Abstract
The presence of Emerging Pollutants (EPs) on the beaches of Acapulco, Mexico, is evaluated for the first time. Samples were taken from the discharge of the wastewater treatment plant at Olvidada beach, and at three beaches that receive contributions from different streams that cross through the city in Santa Lucia Bay (SLB). Using solid phase extraction and gas chromatography/mass spectrometry, 77 EPs were identified. A semiquantitative evaluation of their concentrations were made using the relative areas of the chromatographic peaks, showing that the contamination of the beaches of SLB is mainly due to the pollutants going into the streams of the micro-basins. A statistical factor analysis of all the EPs allowed differentiation of the sampling points, reducing the number of variables, which benefits future analytical determinations in the study area. Due to the toxicological characteristics of the compounds found, their presence on public-use beaches represents a risk to human health.
