摘要
继１９９０年第一次中国总膳食研究后于１９９２～１９９３年进行了第二次中国总膳食研究。本文主要报道研究的总体设计、方法以及四大区重金属和其他有害元素以及农药的膳食摄入量和污染水平，并与ＷＨＯ的ＡＤＩ（每日允许摄入量）和ＰＴＷＩ（暂时每周允许摄入量）值进行比较。重金属铅的平均膳食摄入量比１９９０年略有降低，北方两个区的摄入量明显下降，而南方两个区摄入量明显增加，镉的摄入量普遍增加，而汞的摄入量普遍降低。首次得到铝和氟的总膳食摄入量。有少数元素在个别地区的食物中污染水平超过我国允许量标准，其中，北方一区豆类中汞超标９５．７％；谷类食品中的氟除南方二区外，均超标１１．９％～９５．３％。与１９９０年引比，１９９２年六六六（ＨＣＨ）摄入量大致相近，而滴滴涕（ＤＤＴ）则有所降低。在本次检测的１５种有机磷农药中共检出７种，其膳食摄入量均很低，仅占允许量的１％左右或更低。有机磷农药残留量除南方一区谷类敌敌畏和亚胺硫磷分别占允许残留量的６３．３％和２３．１％外，其他各区各种有机磷农药残留量占允许残留量的０．０５％～５．０９％。与１９９０年不同的是检出了乙酰甲胺磷、马拉硫磷、亚胺硫磷等３种有机磷农药，但未检出敌百虫。
The second Chinese total diet study was carried in 1992-1993.This paper describes the overall design and method of study,and dietary intake of heavy metals and other harmful elements,and pesticides.The average lead and mercury intakes were lower than those in 1990,and the dietary intake of cadmium was higher than that in 1990.The intake of aluminium and fluoride were reported for the first time. The levels of some contaminants in individual areas exceeded the tolerance limit.For example,mercury in North 1 exceeded 95 7% in legumes; fluoride in cereals,except South 2,exceeded 11 9%～95 3%.The intake of HCH was close to that in 1990,and the intake of DDT was lower than that in 1990.Seven out of the fifteen organophosphorus pesticides were detected in this study,although the dietary intakes were low,only accounted for about/or below 1% of ADI. \ \
