Objective To study the determining method of trace amounts of Pb?Cd in nature water body. Methods Pb, Cd in nature water body were concentrated by on-line chelate resin, and concentration was determined by concentration-AAS. Results The Pb and Cd detection limit of the present method were 0.500,0.02 ?g/L respectively, RSD were 2.3%,1.7% respectively and the rates of recovery were 94%-104.4%. Conclusion Using on-line chelate resin concentration technic and atom absorption,the sensitivity will increase two order of magnitudes compared to concentration FAAS,the precision will be better than that of GAAS. The present method can be used for quick determination of trace Pb?Cd in nature water body.

The growth curves and diet of 185 babies in rural area near Beijing from 6 months to 18 months old have been studied. Infants were divided into 3 groups according to their diet taken:(1) 89 babies had breast milk only;(2) 66 babies took more than 250g animal milk per day besides breast milk;(3) 30 babies who did not have breast milk and only animal milk was taken. All the babies were gradually transferred to an ordinary cereal based diet during the weaning period. To half of them a soybean and cereal based formula fortified with minerals and vitamins was supplied, which would provide 6.6g protein and 141 kcal and some other nutrients per day.The results showed that the growth curves of body weight and height of children were much better than the data obtained in 1975, but still lagged behind that of the urban children, especially for the body weight. The weight curves of the babies who took animal milk seemed higher than the other groups. Female babies who were fed with breast milk and supplemented with the weaning food have a better weight and height curves than non-supplemented ones, but this was not seen in males. The hemoglobin contents of the babies who took animal milk when they were 18 months old were lower than that of the 6 months old, but there were no differences in the breast milk groups, and the lowering of the hemoglobin level in the animal milk groups could be corrected by adding weaning food in the diet. When the babies were 6 months old, 39.3% of them had a hair zinc content below the lower limit of the normal range, and it became to 47.6% when they were 18 months old. So zinc deficiency of the babies were present in this local area, and it should be fortified into the weaning food.

A longitudinal study was carried out on fifty infants selected from both urban and rural areas of Beijing for their body weights, heights, head and mid-upper arm circumferences, tricep and abdomen skinfold thicknesses, and breatmilk and energy and protein intakes at the 1st, 3rd and 6th month of life. The results revealed that the breastmilk intakes of these infants were ranged from 600-800 g/day during this period of time, the breastmilk intakes of the rural infants were higher significantly than that of the urban infant throughout the study period (P
