中文摘要:

      目的 了解烟台海域水产品中镉(Cd)含量及其污染程度, 评价膳食水产品来源的Cd致癌(非)健康风险。方法 随机采集4类384份样本; 依据GB 5009.15—2014《食品安全国家标准 食品中镉的测定》规定检测Cd含量; 运用Crystal ball软件, 基于蒙特卡罗拟合计算健康风险概率值。结果 黄渤海海域水产品中Cd的检出率100%, 含量均值为(0.783±0.728) mg/kg, 不同水产品Cd含量由高到低依次为: 甲壳类>腹足类>头足类>双壳贝类>棘皮类>鱼类; 总体不合格率为1.82% (7/384)。青少年和成人居民均存在水产品膳食来源Cd致癌(非)健康风险。非致癌健康风险潜在危害程度40~64岁组>13~17岁组>18~39岁组>65岁以上组, 其风险概率值分别为13.24%、8.73%、7.46%、4.82%; 摄食人群(19.37%)>全人群(3.87%), 女性(13.01%)>男性(9.51%)。致癌健康风险概率值排序为: 65岁以上组>40~64岁组>18~39岁组>13~17岁组, 较高风险概率值分别为97.58%、97.21%、33.69%、20.87%; 致癌健康风险与年龄呈现正相关; 摄食人群与全人群致癌风险相近; 摄入量、Cd含量是控制致癌(非)健康风险的关键因素。结论 黄渤海海域水产品中Cd污染程度的概率值差异较大; 各年龄组均存在潜在膳食水产品来源的Cd健康风险, 水产品的摄入量及Cd含量是健康风险控制的关键因素。

英文摘要:

      Objective To understand the concentration and pollution level of cadmium, and evaluate the carcinogenic (non-) health risk of Cd from dietary aquatic products. Methods Four kinds 384 samples were randomly collected. The Cd concentration was detected by GB 5009.15—2014 National standards for food safety-Determination of cadmium in food, that carcinogenic (non-) health risk probability values were calculated based on Monte Carlo fitting with Crystal ball software. Results The detection rate of Cd was 100% of all kinds aquatic products collected from the Yellow and Bohai Sea area, the mean value was (0.783±0.728) mg/kg. The Cd content of different kinds of aquatic products ranked from high to low was: Crustaceans>gastropods>cephalopods> bivalves>echinoderms>fish, and the unqualified rate was 1.82% (7/384). Both adolescent and adult residents were hazarded potential carcinogenic (non-) health risks from ingested aquatic products. Non-carcinogenic health risk potential hazard level was 40?64 years old>13?17 years old>18?39 years old>over 65 years old, the risk probability values were 13.24%, 8.73%, 7.46%, 4.82%, respectively, intake group (19.37%)>whole population (3.87%), female (13.01%)>male (9.51%). Carcinogenic health risk potential hazard level was over 65 years old>40?64 years old>18?39 years old >13?17 years old, which risk probability values were 97.58%, 97.21%, 33.69%, 20.87%, respectively. The carcinogenic health risk was positively correlated with age, and intake group was similar to that of the whole population. The intake of aquatic products and Cd contention were critical control point that had higher contribution rate. Conclusion The probability values of Cd pollution degree in aquatic products in Yellow and Bohai Sea are different. Potential Cd health risks from dietary aquatic products are present in all age groups, and the intake of aquatic products and Cd contention are critical control point to reduce carcinogenic (non-) health risks.
