【摘要】：目的了解广西部分食品中铝的污染状况,评估居民膳食中铝暴露的风险。方法对2009—2013年广西检测的部分食品中铝含量进行分析,结合2002年广西居民膳食营养调查中的食物消费量数据,计算广西居民膳食中铝暴露量。结果 2009—2013年共检测食品样品10类5 679份,铝含量的平均值为132.17 mg/kg,检出率为73.01%(4 146/5 679),超标率为29.51%(1 676/5 679)。其中以海蜇、紫菜干(海带干)、油条3种食品的检出率和超标率最高,且铝的平均含量也是极高。油条样品中铝含量的均数和中位数均最高,分别超过国家残留量标准的3.8倍和3倍。10类居民膳食中铝平均每周摄入量为0.426 mg/kg BW,低于JECFA制定的每周耐受摄入量(PTWI)。馒头、海蜇、油条和油饼高消费量人群的每周铝摄入量分别是PTWI的3.07、2.40、2.23和1.23倍。结论广西监测的油条、紫菜、海蜇等食品中铝含量超标较严重,居民平均膳食摄入铝的量虽然低于PTWI,但高消费量人群铝的暴露风险较大,仍需要加强对生产经营者科学合理使用含铝添加剂的技术指导,以降低居民膳食中铝的摄入量。
[Abstract]:Objective to investigate the contamination of aluminum in some foods in Guangxi and to evaluate the risk of exposure to aluminum in diet of residents. Methods the aluminum contents in some foods detected in Guangxi from 2009 to 2013 were analyzed and the food consumption data from 2002 to 2002 were used to calculate the amount of aluminum exposure in the diet of Guangxi residents. Results A total of 5 679 samples of 10 kinds of food samples were detected in 2009-2013. The average value of aluminum content was 132.17 mg / kg. The detection rate was 73.01% 4146 / 5679 渭 g / kg, and the rate of exceeding the standard was 29.51% / 5679%. Among them, jellyfish, dried porphyra (dried kelp, oil bar) had the highest detectable rate and over standard rate, and the average content of aluminum was extremely high. The mean and median aluminum content in the samples was the highest, which exceeded the national residue standard by 3.8-fold and 3.0-fold respectively. The average weekly intake of aluminum was 0.426 mg/kg BW, which was lower than that of JECFA-formulated weekly tolerance intake. The intake of aluminum in steamed bread, jellyfish, stick and cruller was 3.072.400.23 and 1.23 times higher than that in PTWI, respectively. Conclusion the content of aluminum in the food monitored in Guangxi is more serious than the standard, and the average dietary intake of aluminum is lower than that of PTWI, but the exposure risk of the high consuming population is higher than that of the high consuming population. In order to reduce the intake of aluminum in the diet of residents, it is still necessary to strengthen the technical guidance on the rational use of aluminum additives for producers.
