摘要: 为探明温州海域水产品中铬(Cr)、铜(Cu)、锌(Zn)、砷(As)、镉(Cd)、汞(Hg)、铅(Pb)7种重金属元素的分布特征,利用高效液相色谱电感耦合等离子体质谱法和电感耦合等离子体质谱技术对从温州海域采集的11种海洋生物样品中的重金属含量进行测定,综合采用单因子污染指数法、综合污染指数和食用安全性评估等方法全面评价样品的重金属污染程度及其健康风险。结果表明:样品中Hg、As(以无机砷计)、Cd、Pb、Cr、Cu、Zn含量的平均值分别为0.015、0.035、0.17、0.14、0.23、4.38、12.13 mg·kg-1。对照GB 2762—2022《食品安全国家标准 食品中污染物限量》,样品中Cr、Cd、Hg、As、Pb含量的平均值均未超标。单因子污染指数评价的结果显示,三疣梭子蟹(Portunus trituberculatus)的重金属污染情况相对严重,Cu、Cd、Pb为轻度污染,Zn为中度污染。此外,三疣梭子蟹的综合污染指数值也最高,为0.46。食用安全性评估结果显示,供试样品的健康风险较低。供试样品的目标危险系数(THQ)和危害指数(HI)值均低于1,表明其食用安全性较高。总体来看,本次检测的温州海域水产品的重金属安全风险较低,但三疣梭子蟹和厚壳贻贝(Mytilus coruscus)的HI值分别达到0.680和0.526,须对其加强风险监测。

Abstract:

In order to characterize the distribution of seven heavy metal elements, namely chromium (Cr), copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), mercury (Hg) and lead (Pb), in marine products in the sea area of Wenzhou, China, high performance liquid chromatography with inductively coupled plasma mass spectrometry and inductively coupled plasma mass spectrometry techniques were utilized to determine the heavy metals contents in 11 marine biological samples. The single factor pollution index, comprehensive pollution index and food safety assessment method were used to comprehensively evaluate the heavy metals pollution level and their health risk of these samples. It was shown that the average contents of Hg, inorganic As, Cd, Pb, Cr, Cu, Zn were 0.015, 0.035, 0.17, 0.14, 0.23, 4.38, 12.13 mg·kg-1, respectively. According to the National Food Safety Standard Contamination Limit in Food (GB 2762—2022), the average contents of Cr, Cd, Hg, As, Pb in these samples were below the limit. Based on the the single factor pollution index, the heavy metals pollution level of Portunus trituberculatus was relatively higher, with mild pollution of Cd, Cd, Pb and moderate pollution of Zn. Besides, the comprehensive pollution index value of P. trituberculatus was also high, which reached 0.46. In terms of food safety assessment, all the samples showed low risk. The target hazard quotient (THQ) and hazard index (HI) values of all the samples were smaller than 1. Therefore, the collected samples all showed low ecological and health risk, indicating high safety for consumption. In general, this survey exhibited low heavy metals pollution risk in the marine products in the sea area of Wenzhou. However, the HI value of P. trituberculatus and Mytilus coruscus reached 0.680 and 0.526, respectively, which called for more attention on the risk monitoring and assessment.
