【摘要】 目的了解甘肃省金昌市2~7岁儿童血铅水平。方法随机抽取2004年10月~2005年6月金昌市部分幼儿园256名儿童。男133名,女123名;用石墨炉原子吸收分光光度仪测定血铅水平。结果儿童血铅水平为(126.30±52.98)μg/L。血铅水平最低值为28.3μg/L,最高值为268.0μg/L,超过100μg/L者160例,占62.54%。血铅水平随年龄增加有上升趋势,2~3岁组明显低于5~6岁组、6~7岁组,差异有统计学意义(P<0.05,0.01);性别间血铅水平差异无统计学意义(P>0.05)。结论甘肃金昌市儿童血铅水平较高,铅中毒现象不容忽视。更多还原

【Abstract】 Objective To estimate blood lead level of children in Jinchang city of Gansu province.Methods According to relevant request,256 children(male 133,female 123) aged 2-7 years from some kindergartens in Jinchang city were randornly selected from Oct. 2004 to Jun. 2005. Blood lead level was measured by atom-absorbing graphiteingle method.Results The average blood lead level of 256 children was(126.30±52.98)μg/L.The lowest blood lead level was 28.3 μg/L while the highest was 268.0 μg/L.And 160 children(62.54%) were found with a blood lead level ≥100 μg/L(the diagnostic level of lead poisoning in children).The blood lead level became higher with the increase of children′s age,as groups aged 2-3 years group were lower than aged 5-6 years and 6-7 years groups,of which the differenes had statistical significance(P<0.05,0.01).There was no difference between sexs(P>0.05).Conclusion Blood lead levels of children in Jinchang city and prevalence of lead poisoning are both relatively higher,to which enough attention shall be paid.更多还原
