The marine environment is severely contaminated by anthropogenic activities. Among the pollutants are metals such as mercury (Hg), chromium (Cr), and zinc (Zn), elements commonly found in industrial effluents from steel mills. This study aims to quantify the concentrations of Hg, Cr, and Zn in seafood samples (crab and mussels) and conduct a consumption risk analysis, considering the seasonality and sexual dimorphism of the animals. The samples were collected from traditional fisheries in Itaipu, Niterói, Rio de Janeiro, Brazil. Muscle samples were removed from the animals, which served as the basis for determining Hg, Cr, and Zn levels. Consumption risk assessment was also conducted following the Estimated Monthly Intake and Hazard Quotient (HQ). The quantification results were below the limits set by international regulatory agencies. However, the risk analysis for the population revealed some HQ values above one, particularly for crab consumption.
海洋环境受到人类活动的严重污染。污染物中包括汞（Hg）、铬（Cr）和锌（Zn）等金属，这些元素常见于钢铁厂的工业废水中。本研究旨在量化海鲜样本（螃蟹和贻贝）中汞、铬和锌的浓度，并考虑动物的季节性和性别二态性进行消费风险分析。样本采集自巴西里约热内卢尼泰罗伊伊泰普的传统渔场。从动物身上取出肌肉样本，作为测定汞、铬和锌含量的基础。还按照估计月摄入量和危害商数（HQ）进行了消费风险评估。量化结果低于国际监管机构设定的限值。然而，对人群的风险分析显示，一些HQ值高于1，尤其是食用螃蟹时。
