目的了解西安市0～6岁男、女儿童血铅水平及铅中毒状况。方法采用原子吸收光谱法,对2004-2006年西安市0～6岁2673名儿童进行血铅的测定,并对男女不同性别组间检测结果进行了比较和分析。结果西安市0～6岁儿童血铅中毒率为7.7%;男、女儿童组中毒率分别为8.9%、6.7%;2004年、2005年、2006年的儿童铅中毒率分别为13.4%、4.6%、5.4%。结论西安市0～6岁儿童铅中毒率较高,男童明显多于女童,有显著性差异(P<0.05)。结果分析2004年铅中毒率高可能与我们所调查儿童的父母中有三分之一是从事建材销售或与铅相关的的职业有关,调查提示铅中毒还与家庭环境、个人卫生习惯、住房等诸多因素有关。

Methods The blood lead levels of 2673 children aged 0-6 years old in Xi’an from 2004 to 2006 were measured by atomic absorption spectrometry. The results of the sexes test were compared and analyzed. Results The lead poisoning rate of children aged 0-6 years in Xi’an was 7.7%. The rates of poisoning in boys and girls were 8.9% and 6.7% respectively. The lead poisoning rates of children in 2004, 2005 and 2006 were 13.4% and 4.6% respectively %, 5.4%. Conclusion The lead poisoning rate of children aged 0 ~ 6 years in Xi’an is higher than that of girls, there are significant differences (P <0.05). Analysis of the results The high rate of lead poisoning in 2004 may be related to one third of the parents of the children we surveyed engaged in sales of building materials or occupations related to lead. The survey suggests that lead poisoning is also related to the family environment, personal hygiene habits, housing, etc. Many factors related.
