Naturally existing and human-produced heavy metals are released into the environment and cannot be completely decomposed by microorganisms, but they continue to accumulate in water and sediments, causing organisms to be exposed to heavy metals.
This study designs and proposes heavy metal hazard decision trees for aquatic products, which are divided into seven categories including pelagic fishes, inshore fishes, other fishes, crustaceans, shellfish, cephalopods, and algae. Based on these classifications, representative fresh and processed seafood products are at the root of the heavy metal hazard decision trees. This study uses 2,107 cases of eating 556 cooked fresh or processed seafood product samples. The constructions of the proposed decision trees consist of 12 heavy metals, which include inorganic arsenic (iAs), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), strontium (Sr), thallium (Tl), and zinc (Zn). The heavy metal concentrations in cooked fresh and processed seafood product samples are subjected to a food safety risk assessment.
The results indicate the relationships among the seven categories of aquatic products, the relationships among 12 heavy metals in aquatic products, and the relationships among potential human health risks. Finally, the proposed heavy metal hazard decision trees for aquatic products can be used as a reference model for researchers and engineers.
自然存在和人为产生的重金属会释放到环境中，不能被微生物完全分解，但它们会继续在水中和沉积物中积累，使生物体暴露于重金属之下。
本研究设计并提出了水产品重金属危害决策树，分为包括远洋鱼类、近岸鱼类、其他鱼类、甲壳类、贝类、头足类和藻类在内的七大类。基于这些分类，有代表性的新鲜和加工海产品处于重金属危害决策树的根部。本研究使用了 2107 例食用 556 种新鲜或加工海鲜产品样本的案例。所提出决策树的构建由 12 种重金属组成，包括无机砷（iAs）、镉（Cd）、钴（Co）、铬（Cr）、铜（Cu）、铁（Fe）、锰（Mn）、镍（Ni）、铅（Pb）、锶（Sr）、铊（Tl）和锌（Zn）。对新鲜和加工海产品样本中的重金属浓度进行了食品安全风险评估。
结果表明了七类水产品之间的关系、水产品中 12 种重金属之间的关系以及潜在的人类健康风险之间的关系。最后，所提出的水产品重金属危害决策树可作为研究人员和工程师的参考模型。
