| 摘 要： | 为了解浙江沿海藻类重金属污染情况,评价人体经藻类途径摄入重金属的健康风险,采用电感耦合等离子体质谱法(ICP-MS)测定3种藻类样品中Pb、Cd、As、Hg含量,并与食品中污染物限量标准进行比较,基于美国环保署(USEPA)2000年提出的健康风险模型,通过计算目标危害系数(THQ、TTHQ)的方法预测藻类中重金属对人体的健康风险。结果显示,34份藻类样品中,83.33%羊栖菜和100%紫菜的镉,16.67%羊栖菜、44.44%海带和100%紫菜的铅,100%羊栖菜和66.67%海带的无机砷含量超过国家标准限量值。从单一重金属风险来看,成人摄入所调查的3种藻类虽然尚属安全,但羊栖菜和海带的砷、紫菜的镉应引起重视,儿童膳食途径摄入所调查的3种藻类可能存在砷和镉的膳食摄入潜在风险,尤其是羊栖菜和海带的砷、紫菜的镉。从多种重金属复合风险来看,成人和儿童摄入所调查的3种藻类可能存在潜在健康风险,成人和儿童的潜在复合健康风险主要由无机砷和镉引起。

| Abstract: | In order to investigate heavy metal pollution status in algae in Zhejiang Province and assess its risk to human health, inductively coupled plasma-mass spectrometry (ICP-MS) was used to detect the contents of Pb, Cd, As and Hg in three kinds of algae. The measured values were compared with current relevant standards in China. To anticipate the risks of heavy metal in algae, target hazard quotients (THQ and TTHQ) were calculated based on the health risk model proposed by the US Environmental Protection Agency (USEPA) in 2000. The results based on 34 samples showed that the standard-exceeding rates of Cd were 83.33% in Sargassum fusiform and 100% in porphyra. The standard-exceeding rates of Pb in Sargassum fusiform, Laminaria japonica, and porphyra were 16.67%, 44.44% and 100%, respectively, and the standard-exceeding rates of inorganic arsenic in Sargassum fusiform and Laminaria japonica were 100% and 66.7%, respectively. The three kinds of algae tended to be safe for adult, but posed a potential risk to children based on the health risks of single heavy metal pollution, especially the pollution of As in Sargassum fusiform and Laminaria japonica, and Cd in porphyra. Based on the assessment of health risks posed by multiple heavy metal pollution, these algae were found to be dangerous both for adult and children. The overall health risks of heavy metals were mainly due to As and Cd pollutions. |
