基于虾蛄食用习惯的镉膳食风险研究

Study on the Risk of Cadmium Based on the Dietary Habits of Mantis Shrimp

为了研究食用高镉虾蛄的膳食风险,本文采用去除肠腺和保留肠腺两种方法对虾蛄样品进行处理,检测总镉含量,以评估肠腺对总镉含量影响。然后采用点评估法对虾蛄样品中最大镉含量进行风险评估。结果表明,保留肠腺的虾蛄总镉含量是去除肠腺总镉含量的2.39倍,保留肠腺的虾蛄有一定的膳食安全风险,建议去除肠腺食用虾蛄;运用危害商数法得到最大总镉THQ为0.62,最大生物有效性镉THQ为0.062,均小于1,表明高镉虾蛄没有明显的食用风险。

In order to study the dietary risk of high cadmium consumption of mantis shrimp,two methods were used to treat mantis shrimp samples with intestinal gland removal and intestinal gland retention,and the total cadmium content was detected to evaluate the effect of intestinal gland on total cadmium content.Then point assessment method was used to assess the risk of maximum cadmium content in mantis shrimp samples.The results showed that the total cadmium content in mantis shrimps with intestinal glands retained was 2.39 times that without intestinal glands,indicating that the mantis shrimps with intestinal glands had a certain dietary safety risk,and it was recommended to eat mantis shrimps without intestinal glands.The maximum total cadmium THQ was 0.62,and the maximum bioavailability cadmium THQ was 0.062 both of which were less than 1,indicating that high cadmium mantis shrimp had no obvious dietary risk.
