The impact of urban and agricultural development on sediment quality in the Alvarado Lagoon region in the southern Gulf of Mexico requires an examination of the historical behavior of potential toxic metals (PTMs) and polycyclic aromatic hydrocarbons (PAHs). Consequently, this study aims to assess the ecotoxicological hazards that benthic species and human consumers face in the area. These results are crucial for economic acti...

Polycyclic aromatic hydrocarbons (PAHs) are organic chemicals that consist of carcinogenic and mutagenic properties, which are considered as high-priority persistent organic pollutants (POPs). Their source is due to an incomplete burning of fossil fuels and organic materials. In the present study, the distribution and concentrations of 16 priority PAHs in sediments of the Tampamachoco lagoon and Tuxpan River estuary at the Gul...
