摘要:

测定几种海产品(软体类、甲壳类、鱼类)中重金属Hg、Cd 、Pb 的含量,并运用危害商数(target hazard quotients,THQs)评价食用海产品对人体健康的潜在风险。结果发现:Hg 在软体类生物中的含量范围为0.06~1.23mg/kg,其次为鱼类(0.024~1.03mg/kg),甲壳类生物最低(未检出~0.25mg/kg);Cd 在软体类生物中的含量为 0.18~4.02mg/kg,高于甲壳类(未检出~0.05mg/kg)和鱼类(未检出~0.07mg/kg);Pb含量较低,软体类(0.04~0.23mg/kg)、甲壳类(未检出0.03mg/kg)、鱼类(未检出~0.07mg/kg)。Cd 和Pb 的危害商数说明该市场的海产品中这两种金属对人体健康不具有潜在风险,相比之下,重金属汞在某一种鱼中的危害商数可能对人体健康有潜在风险。

Abstract:

The contents of heavy metals including Hg, Cd and Pb in edible marine products such as molluscs, crustaceans, and fish from a local market in Lianyungang were determined to evaluate the potential risks to health on the basis of target hazard quotients (THQs). Results indicated that mercury had the highest concentration in molluscs (0.06-1.23 mg/kg), followed by fish (0.024-1.03 mg/kg), and crustaceans (less than 0.25 mg/kg). Cadmium level in molluscs was in the range of 0.18 to 4.02 mg/kg, which was higher than that in crustaceans (less than 0.05 mg/kg) and fish (less than 0.07 mg/kg). However, Pb level was generally low, which was between 0.04 mg/kg and 0.23 mg/kg in molluscs, less than 0.03 mg/kg in crustaceans, and less than 0.07 mg/kg in fish. According to the THQ values of Cd and Pb, there is no risk to health after consuming these seafoods from this market. In contrast, according to the THQ values of mercury, one kind of fish (Platycephalus indicus) has the risk to health during consumption.

Key words: seafood, heavy metal, health risk assessment, target hazard quotients (THQs)
