| 重金属污染是渤海长期面临的环境问题之一,同时对渤海海产品安全和人体健康构成潜在风险。为了解渤海海域鱼类重金属污染状况,在该海域采集的渔业生物中随机选取了10种144条鱼类样本,运用电感耦合等离子体质谱法测定了鱼类肌肉组织中重金属Cu、Zn、Pb、Cd、Cr和As的含量；采用单因子污染指数法、内梅罗综合污染指数法和金属污染指数法评价了单一重金属和综合重金属污染情况；采用每日摄入量和目标危害系数评估了渤海鱼类重金属污染对人体的食用安全风险。研究结果表明,渤海鱼类肌肉中重金属Cu、Zn、Pb、Cd、Cr和As的平均含量分别为(0.093±0.091) mg/kg、(9.697±5.261) mg/kg、(0.035±0.589) mg/kg、(0.029±0.035) mg/kg、(0.093±0.091) mg/kg和(0.905±0.810) mg/kg。与我国其他海域相比,渤海鱼类重金属含量处于较高水平。鱼类重金属污染评价结果显示, Cd和iAs为渤海鱼类重金属污染的主要元素,细纹狮子鱼受到重金属综合污染的程度最大。食用风险评估结果表明,摄食渤海鱼类带来的重金属每日摄入量处于较低水平,所有鱼类样本单一重金属和综合重金属THQ值均小于1,表明摄食渤海鱼类不会对消费者构成健康风险。本研究结果有助于加深理解渤海渔业生物的重金属污染状况,同时为保障渤海渔业产品的食用安全提供了重要的科学依据。 |
| 英文摘要: |
| The Bohai Sea, being China"s only semi-enclosed inland sea, has received significant inputs of heavy metals from the rapidly industrializing and urbanizing Bohai Sea Economic Rim. Due to limited water exchange and self-purification capacity, heavy metal pollution in the Bohai Sea has been intensifying, making it a focal area of heavy metal pollution research. Furthermore, the Bohai Sea serves as one of China"s traditional fishing grounds, acting as both a spawning area and foraging ground for various economically significant fishery species, thereby providing abundant seafood for urban and rural communities in the Bohai Sea region. Heavy metals are regarded as one of the principal pollutants in the marine environment of the Bohai Sea due to their high accumulation and resistance to degradation. They accumulate within organisms and are subsequently transferred through the food chain, resulting in the pollution of marine biological resources. The issue of heavy metal pollution in the Bohai Sea has raised concerns among researchers regarding food product safety and human health risks. |
