The concentrations of dissolved trace metals (Fe, Mn, Cr, Cu, Co, Ni, Pb, Zn, Cd, Sr, V, As) were analyzed in 56 water samples from the intertidal zone of the Mexican Caribbean coast during 2019 and 2020. The higher concentrations of dissolved metals (especially Pb, Ni, Cd) in 2019, suggest the influence of anthropogenic inputs mainly related to an intense development of tourism in the region. In 2020, higher variability was observed in the distribution pattern of metals related to the reduction in tourism activity due to the COVID 19 pandemic and the simultaneous enrichment effect from the runoff during the rainy episodes. The generation of anoxic regions in some beaches due to the great accumulation of Sargassum influences the mechanisms of mobilization/enrichment of dissolved metals (especially Ni, Cd). The concentrations of metals showed an increase of two (Ni) to ten times (Pb and As) in the coastal region, which suggests the urgent need for continuous monitoring that supports an adequate management program of the Mexican Caribbean coast.
