In order to mitigate the risk of excessive heavy metal intake, a study was conducted to assess the levels of arsenic (As), cadmium (Cd), chromium (Cr), and lead (Pb) contamination in 23 edible seafood species obtained from markets in Haikou. The findings were analyzed to evaluate the potential health hazards posed to the local population through consumption. The metals were detected via inductively coupled plasma mass spectrometry (ICP-MS) for quantification. The non-carcinogenic and carcinogenic health risks in humans were assessed via target hazard quotient (THQ), combined target hazard quotient (CTHQ), and target cancer risk (TR). The results indicated that the rank order based on the median metal concentration was As > Cd > Cr > Pb. THQ and CTHQ showed that nine seafood species posed a non-carcinogenic risk regarding from As and Cd consumption separately, or the four targeted metals ingestion together. TR assessment indicated that the InAs in all the species presented a carcinogenic risk to coastal residents. The Cd content in bivalves, algae, and several crustacean (Mantis Shrimp, Orchid Crab, Red spot Swimming Crab) and fish species (Japanese Scad, Pacific Saury), and Cr levels in most bivalve species (Razor Clams, White Clams, Fan Shells, Oysters, Blood Clams) presented a carcinogenic risk. The As, Cd, Pb, and Cr levels of seafood in Haikou were assessed species presented a potential health risk. Necessitating stricter risk should be management and detection capability and monitoring will be improved.
为了降低重金属摄入过量的风险，本研究对海口市场上采集的 23 种食用海鲜中的砷（As）、镉（Cd）、铬（Cr）和铅（Pb）污染水平进行了评估，以评估当地居民因食用这些海鲜而面临的潜在健康危害。采用电感耦合等离子体质谱法（ICP-MS）对金属进行检测和定量分析。通过目标危害系数（THQ）、综合目标危害系数（CTHQ）和目标癌症风险（TR）评估非致癌和致癌健康风险。结果表明，基于金属浓度中位数的排序顺序为 As>Cd>Cr>Pb。THQ 和 CTHQ 表明，9 种海鲜品种分别因摄入 As 和 Cd，或四种目标金属摄入而存在非致癌风险。TR 评估表明，所有品种中的 InAs 对沿海居民具有致癌风险。贝类、藻类和几种甲壳类（螳螂虾、兰花蟹、红斑游泳蟹）和鱼类（日本沙丁鱼、太平洋秋刀鱼）中的 Cd 含量，以及大多数贝类（蛤蜊、白蛤、扇贝、牡蛎、血蛤）中的 Cr 含量均存在致癌风险。海口海鲜中的 As、Cd、Pb 和 Cr 水平存在潜在健康风险。需要加强风险管理和检测能力，提高监测水平。
