The total diet study on various age-sex groups and the comparison of two seasons (spring and autumn) in adult male were conducted in the second Chinese Total Diet Study in 1992-1993. The dietary pattern, dietary intake of heavy metals and other harmful elements and radionuclides were studied in 4 age-sex groups in 4 provinces and cities, i.e. Hebei, Shanxi, Hubei and Shanghai. The contamination of lead in diet was the most outstanding finding. The intake of lead in 2-7 years old exceeded 18.9% of the ADI. The contamination of cadmium and mercury in diet were low, and the dietary intake were 24% and 35% of the ADI respectively. The dietary intakes of aluminium in the two young groups exceeded about 8% of the ADI. The intake of dietary fluoride in the two young groups were a little too low, and it was adequate in the adult groups. The overall dietary intake of radionuclides in the 4 age-sex groups was only 36% of ALI. The intakes of man-made radionuclides, 90Sr and 137Cs were all below 1% of ALI. The comparisons of two seasons (spring and autumn) showed that the overall intakes of radionuclides were higher in autumn than in spring. The intake of 210Pb was 3-4 times in autumn than in spring.
1992 - 1993年开展的第二次中国总膳食研究中，对不同年龄 - 性别组进行了总膳食研究，并对成年男性的两个季节（春季和秋季）进行了比较。在河北、山西、湖北和上海4个省市的4个年龄 - 性别组中，研究了膳食模式、重金属及其他有害元素和放射性核素的膳食摄入量。膳食中铅污染是最突出的发现。2 - 7岁儿童铅摄入量超过每日允许摄入量（ADI）的18.9%。膳食中镉和汞污染较低，膳食摄入量分别为ADI的24%和35%。两个较年轻组的铝膳食摄入量超过ADI的约8%。两个较年轻组的膳食氟摄入量略低，而成年组摄入量充足。4个年龄 - 性别组放射性核素的总体膳食摄入量仅为年摄入量限值（ALI）的36%。人造放射性核素、90锶和137铯的摄入量均低于ALI的1%。两个季节（春季和秋季）的比较表明，秋季放射性核素的总体摄入量高于春季。210铅秋季摄入量是春季的3 - 4倍。
