为连续观察我国膳食质量的变化，继１９９０年第一次总膳食研究之后于１９９２年进行了第二次总膳食研究。本研究对四个大区９类食物中有机氯农药（ＨＣＨ，ＤＤＴ）和三类食物中１５种有机磷农药进行测定。ＨＣＨ总摄入量各区间无明显差别，与１９９０年相比也无明显差别。ＤＤＴ总摄入量与１９９０年相比均有所下降，且各大区间亦无差别。在被检测的１５种有机磷农药中共检测出７种，其中高毒性、中毒性、低毒性分别占检出农药样品的１１．７％，６４．７％和２３．５％。南方一区谷类敌敌畏占允许残留量的６３．３２％，亚胺硫磷占允许残留量的２３．１０％，其它各区各种有机磷农药残留量占允许量的０．０５％～５．０９％。
To continuously observe the changes in dietary quality in our country, a second total dietary study was conducted in 1992 following the first total diet study in 1990. In this study, the organochlorine pesticides (HCH, DDT) and the 15 kinds of organophosphorus pesticides in three kinds of food in four regions were determined. HCH total intake of each interval no significant difference, compared with 1990 no significant difference. Total DDT intake declined compared with 1990, and there was no difference in major sections. Among the 15 kinds of organophosphorus pesticides tested, 7 were detected, of which 11.7%, 64.7% and 23.5% were highly toxic, toxic and low toxicity, respectively. In south China, DDV accounted for 63.32% of the allowable residues, imines met 23.10% of allowable residues, and residues of other organophosphorus pesticides in other districts accounted for 0.05% -5.09 %.
