Fecha de publicación: | 4-may-2023 | Editor: | Springer | Citación: | Bulletin of Environmental Contamination and Toxicology 110: e89 (2023) | Resumen: | In the present study, livers, kidneys and adipose tissue of Yellow-legged Gull (Larus michahellis) were collected. Samples were used to determine relationships between heavy metals/metalloids in liver and kidneys (Hg, Cd, Pb, Se and As) or persistent organic pollutants in adipose tissue (7 PCBs and 11 organochlorine pesticides) with biomarkers of oxidative stress (CAT, GPx, GR, GSH, GST, MDA) analysed in both internal organs. Three possible influencing variables have been studied: age, sex and sampling area. As a result, statistically significant differences (P < 0.05, P < 0.01) were only found according to the sampling area, with differences among the three studied areas found in both organs. Significant positive correlations (P < 0.01) were found in liver (Hg vs. GST; Se vs. MDA) and in kidney (As vs. GR; As vs. GPx; PCB52 vs. CAT; PCB138 vs. CAT). The scarcity in correlations suggests that the levels of pollutants found in animals were not high enough to trigger an effect at the oxidative level. | Versión del editor: | https://doi.org/10.1007/s00128-023-03729-1 | URI: | http://hdl.handle.net/10261/311122 | DOI: | 10.1007/s00128-023-03729-1 | ISSN: | 0007-4861 | E-ISSN: | 1432-0800 |
