abstract: Tourism, urban development, and sargasso beaching caused environmental alterations in the Mexican Caribbean coasts. Little ecotoxicological information exists on the green turtle (Chelonia mydas) population inhabiting this region. Micronucleus (MN) and erythrocytic nuclear abnormalities (ENA) tests are non-destructive DNA damage biomarkers. We aimed to determine local (Punta Arenas, Akumal, Punta Herrero, and Xcalak) and annual (2015–2019) variability in MN/ENA frequency to understand genotoxic damage extent. Almost all the individuals sampled (n = 166) presented DNA damage (98.8%25); the lack of correlations between MN/ENA and biological variables confirmed the usefulness of these tests as biomarkers. The southern foraging site had the highest number of MN/ENA; an increase over time was found in the most urbanized and the most protected sites, coinciding with previously reported regional variability of persistent organic compounds, heavy metals, and annual massive influx of sargasso. Considering the sentinel status of green turtles, the advantages of the blood tests, and the continuous accelerated urban development in the Caribbean, long-term monitoring of this species is advised.
