暨南大学团队:中国市场上婴幼儿食品中氯化石蜡污染情况
创作:尹小甜 审核:Epi汪 02月19日
  • 对中国市场上三种常见婴儿食品(配方奶粉、谷物、果泥)中的短链和中链氯化石蜡(SCCPs、MCCPs)进行检测;
  • 三种食物中SCCPs的平均浓度分别是7.95、4.26和4.66ng/g,而MCCPs的平均暴露浓度为4.77、2.91和1.89 ng /g;
  • 全脂牛奶样品中的氯化石蜡浓度显著高于其他婴儿食品;
  • 根据摄入量估计,暂不能认为婴儿食品中氯化石蜡污染存在健康风险;
  • 动物源性食品比植物源性食品更易受到MCCPs的影响。

氯化石蜡被大量用作塑料和橡胶工业的增塑剂和阻燃剂,其是食物中常见的环境污染物之一。其已经被列入2B类致癌物清单中。本研究为暨南大学团队针对我国市场上婴幼儿食品中氯化石蜡的污染情况进行的调查,结果显示暂未见婴儿食品中氯化石蜡污染造成的健康风险。

Abstract:收起
Food intake has been identified as a major route for infants to short- and medium-chain chlorinated paraffins (SCCPs and MCCPs, respectively), but evaluations of SCCPs and MCCPs exposure for infants via dietary sources are limited. Here, SCCPs and MCCPs were analyzed in three categories of commonly used infant foods from the Chinese market. The mean concentrations (range) of SCCPs in infant formulas, cereals, and purees were 7.95 (2.32–54.2), 4.26 (2.73–8.81), and 4.66 (1.33–8.43) ng g−1 fresh weight, respectively, and the mean (range) MCCP concentrations were 4.77 (1.67–20.9), 2.91 (1.21–8.24), and 1.89 (0.53–5.41) ng g−1 fresh weight, respectively. Chlorinated paraffins (CP) concentrations in whole milk samples were significantly higher than those detected in the other infant foods (p < 0.01). This study is the first to determine the occurrence of CPs in baby purees. The estimated margin of exposure (MOE) values (SCCPs-MOE and MCCPs-MOE) in this study were all greater than 1000, indicating that there were no health risks posed by CP contamination in infant foods. Principal component analysis indicated that foods of animal origin were more influenced by MCCPs than those of plant-origin, indicating different contamination patterns of CPs between food groups.
