Trace metal (TM) concentrations and carcinogenic risk were determined in ninety-two edible samples of the triggerfish spp. from the RAMSAR site 1826 San Ignacio-Navachiste-Macapule Lagoon Complex (NAV). The acid digestion method and an atomic absorption spectrophotometer were used to determine TM concentrations. Calibration curves were carried out using TORT-3 reference materials. The blank and certified reference materials were treated using the same procedure as a sample. TM sequence was Zn > Fe > Mn > Cu = Pb > Ni > Cd, and a correlation ( = 0.0169) between size and concentrations was found. No correlation ( = 0.079) was found between weight and concentrations, or sampling sites and the concentrations. The highest concentrations were found during the summer, followed by the spring and winter of 2017, while the lowest was found in the winter of 2018. The Zn was significantly higher in summer-17. The Target Hazard Quotient (THQ) was <1 for Pb, Ni, Cd, Fe, Zn, and Cu, and 1.39 for Mn. Cd and Pb resulted in carcinogenic potential (CsFo < 1) with a very low probability. The TM concentrations and bioaccumulation in triggerfish showed no consumption risk, due to its omnivorous diet, and trophic transfer rates were described for aquatic food webs.
测定了来自拉姆萨尔湿地1826号圣伊格纳西奥-纳瓦奇斯特-马卡普尔泻湖复合体（NAV）的92份食用扳机鱼样本中的痕量金属（TM）浓度及致癌风险。采用酸消解方法和原子吸收分光光度计测定TM浓度。使用TORT-3标准物质绘制校准曲线。空白和标准参考物质的处理程序与样品相同。TM顺序为锌>铁>锰>铜=铅>镍>镉，且发现尺寸与浓度之间存在相关性（r = 0.0169）。未发现重量与浓度或采样地点与浓度之间存在相关性（r = 0.079）。夏季浓度最高，其次是2017年春季和冬季，而2018年冬季浓度最低。2017年夏季锌含量显著更高。铅、镍、镉、铁、锌和铜的目标危险商（THQ）<1，锰为1.39。镉和铅导致致癌潜力（CsFo < 1）的概率非常低。扳机鱼中的TM浓度和生物累积显示不存在食用风险，因其杂食性饮食，并描述了水生食物网的营养转移率。
