【Abstract】 To explore the effects of blood lead level on physical development in pre school children. 264 pre school children aged 3～5 years were determined for blood lead content and evaluated for physical development. When 0.483 μmol/L(diagnostic criteria for lead poisoning in young children formulated by centers for disease control of America)was regarded as the line of demarcation, there were no effects of blood lead level on physical development to be found.[Conclusions] Although effects of blood lead level on children’s physical development were not found in the studies,but the effects of blood lead on neurosis development had already been confirmed. Lead exposure should be reduced in children.更多还原
