The environmental quality differences between two groups of reefs in the Veracruz Reef System were evaluated. The North group of reefs is very close to Veracruz, an urban and port zone, whereas the South group is more isolated, with minor anthropogenic disturbances. To prove the hypothesis that the North group is more affected by anthropogenic activities, the concentrations of hydrocarbons in liver, metals and metalloids such as Se, As, Ba, Cd, Hg and V in muscle, and PAH metabolites in bile were evaluated, and related to biomarkers (transcript abundance of cytochrome P4501A, Vitellogenin, and Glutathione-S-transferase) in two species of fish: Haemulon aurolineatum and Ocyurus chysurus. H. aurolineatum presents the highest concentrations for many pollutants, but O. chysurus shows the most significant differences in pollutant concentrations and biomarkers between the two reef groups, suggesting that this species could be used as a sentinel in future studies in the Gulf of Mexico.
对韦拉克鲁斯礁系统中两组珊瑚礁的环境质量差异进行了评估。北部珊瑚礁群非常靠近韦拉克鲁斯，这是一个城市和港口区域，而南部珊瑚礁群则更为孤立，人为干扰较小。为了验证北部珊瑚礁群受人为活动影响更大这一假设，对肝脏中的碳氢化合物浓度、肌肉中的金属和类金属（如硒、砷、钡、镉、汞和钒）以及胆汁中的多环芳烃代谢物进行了评估，并将其与两种鱼类（金线海猪鱼和黄尾鰤）的生物标志物（细胞色素P4501A、卵黄蛋白原和谷胱甘肽-S-转移酶的转录丰度）相关联。金线海猪鱼在许多污染物中呈现出最高浓度，但黄尾鰤在两个珊瑚礁群之间的污染物浓度和生物标志物方面表现出最显著差异，这表明该物种可在未来墨西哥湾的研究中用作哨兵物种。
