A significant impact of marine pollution is the contamination of seafood which has raised concerns due to its potential human health risks. This current study investigated seasonal bioaccumulation of 9 heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) in 14 commercially important seafood species, including 4 fish, 5 molluscs, and 5 crustacean species. Samples were collected from Pattani Bay, Pattani province, Thailand, during the dry (July 2020) and wet (February 2021) seasons. The edible samples were analyzed for heavy metal concentrations using a flame atomic absorption spectrophotometer. The bioaccumulation trend of heavy metals decreased in the sequence of molluscs > crustaceans > fish. The possible human health risks associated with heavy metal-contaminated seafood consumption were assessed. The parameters investigated for non-carcinogenic and carcinogenic were target hazard quotient (THQ), total hazard index (HI), and target cancer risk (TR). The average ranges of THQs (7.79 × 10−8−8.97 × 10−3), HIs (4.30 × 10−5−1.55 × 10−2), and TRs (2.70 × 10−9−1.34 × 10−5) were observed in the studied seafood species. The results revealed no non-carcinogenic and carcinogenic health risks from consuming these 14 kinds of seafood.
海洋污染的一个重大影响是海产品受到污染，由于其对人类健康存在潜在风险，这引发了人们的担忧。本研究调查了14种具有商业重要性的海产品（包括4种鱼类、5种软体动物和5种甲壳类动物）中9种重金属（镉、钴、铬、铜、铁、锰、镍、铅和锌）的季节性生物累积情况。样本于泰国北大年府北大年湾在旱季（2020年7月）和雨季（2021年2月）采集。使用火焰原子吸收分光光度计对可食用样本的重金属浓度进行分析。重金属的生物累积趋势按软体动物>甲壳类动物>鱼类的顺序递减。评估了食用受重金属污染的海产品可能对人类健康造成的风险。针对非致癌和致癌参数进行调查的分别是目标危害商数（THQ）、总危害指数（HI）和目标癌症风险（TR）。在所研究的海产品种类中观察到THQ的平均范围为（7.79×10−8−8.97×10−3）、HI为（4.30×10−5−1.55×10−2）、TR为（2.70×10−9−1.34×10−5）。结果表明，食用这14种海产品不会带来非致癌和致癌健康风险。
