This study evaluated lead (Pb) content in mangrove root crabs Goniopsis cruentata and performed a risk assessment based on individual frequency of food consumption of the residents of an estuarine village in Brazil. The Pb content in the raw and two forms of processed crabs were analyzed by graphite furnace atomic absorption spectrometry. Based on consumption by the community, estimates of non-carcinogenic target hazard quotients (THQ) were calculated. The mean (± SD) Pb concentrations in raw tissues were: 0.17 (± 0.36), < 0.012 and 0.05 (± 0.09) mg kg⁻¹ (gills, muscle and hepatopancreas), respectively. In the processed products, the highest levels were found in the traditional stew collected in April (2.84 mg kg⁻¹), surpassing the maximum limit allowed. The THQ for consumption of traditional stew was < 1, classified as negligible risk. The G. cruentata of the Jaguaripe River estuary can be considered a safe food, but cooking should be avoided in lead-glazed pottery.

这项研究评估了红树林蟹Goniopsis cruentata中的铅（Pb）含量，并基于巴西一个河口村居民的食物消费量进行了风险评估。用石墨炉原子吸收光谱法分析了生蟹和两种加工蟹中的铅含量。根据社区的消费量，计算出非致癌目标危险商（THQ）的估计值。原始组织中的铅平均（±SD）浓度分别为：0.17（±0.36），<0.012和0.05（±0.09）mg kg ^-1（腮，肌肉和肝胰腺）。在加工产品中，四月份收集的传统炖肉中含量最高（2.84 mg kg ^-1），超出了允许的上限。食用传统炖品的THQ小于1，风险可忽略不计。可以说Jaguaripe河口的G. cruentata是一种安全食品，但是在铅釉陶器中应避免烹饪。
