摘要
目的了解金湖地区儿童、成人膳食汞的摄入量,并评价其安全性。方法收集62名研究对象连续3天的双份饭样本,使用原子荧光光谱分析法测定汞含量。采用联合国粮农组织和世界卫生组织食品添加剂联合专家委员会推荐的暂定每周可耐受摄入量(PTWI)评价金湖地区儿童、成人膳食汞摄入量的安全性。结果金湖地区儿童、成人每周每公斤体重膳食汞摄入量的第97.5百分位数分别为2.92μg/kgbw和1.67μg/kgbw,各占PTWI的58.4%、33.4%。儿童每周每公斤体重膳食汞的摄入量高于成人(z=4.0406,P<0.0001)。结论金湖地区儿童、成人膳食汞的摄入量是安全的,但仍有进一步降低的必要。
Objective To understand the dietary mercuric intakes of children and adults from Jinhu area and assess its safety. Methods The duplicate food portions of 62 subjects were collected over 3 consecutive days. Mercuric levels in duplicate samples were determined by the atomic fluorescence spectrometry. The safety of dietary mercuric intakes of children and adults from Jinhu area was evaluated by using the dietary mercuric PTWI recommended by JECFA of FAO/WHO. Results It was found that the percentile 97.5 weekly dietary mercuric(of PTWI) intakes of children and adults were 2.92μg/kg bw (58.4%),1.67μg/kg bw (33.4%) respectively. The weekly dietary mercuric intakes of children calculated on a body weight basis were higher than that of adults(z=4.0406,P<0.0001). Conclusion Although the dietary mercuric intakes of children and adults are safe,it should be decreased to a lower level. Moreover,the dietary exposure to mercury are higher for children and should be considered seriously.
