【Abstract】 To understand lead content of the blood and its affecting factors for children aged 0～6 years in regions of western Henan province. Blood lead determination was adopted with filter paper method of capillary blood (FP samples).A questionnaire was also conducted. Average of lead content of blood was 0.425 μmol/L in 585 children, of whom 31.96 percent had the higher content than the world recognized diagnostic standard (0.483 μmol/L) for child lead poisoning. The blood lead contents of children varied in different locations, the highest in gold mining areas and the lowest in suburbs. The average values were 0.536 μmol/L and 0.319 μmol/L respectively.Spending longer time on road, often grawing fingers,eating preserved eggs and pulled rice,drinking canned boverage,all these could be increased the blood lead content. [Conclusion] At present,children in regions of western Henan province have higher lead content of blood and much more concern should be given.更多还原
