摘要
目的了解厦门市儿童血铅水平分布状况,为预防儿童铅中毒提供依据。方法随机选择厦门妇幼保健院门诊就诊的儿童,年龄0～10岁,采用原子吸收石墨炉法测定全血血铅值。结果 2010～2013年间共有11 271例儿童检测全血血铅水平,血铅均值为51.0μg/L。不同年龄组的男童铅中毒率高于女童,差异有统计学意义(P<0.05)。在1～6岁期间,随着年龄增加血铅均值逐渐上升,并在学龄前期达到高峰,之后的学龄期儿童均值不再增高,但血铅中毒率始终呈现逐渐下降的趋势。结论厦门市儿童铅中毒率接近国内其他城市平均水平,但学龄前儿童血铅的均值水平随年龄增长而增加,铅污染对儿童身体健康危害应引起重视。
Objective To provide the scientific guidance for the prevention of lead poisoning in the children,the lead concentrations in the blood of children in Xiamen are investigated.Methods 11 271 cases of outpatients with the age of 0-10 years old in maternity and child care hospital were surveyed randomly.The lead concentrations in the blood of these children were determined by graphite furnace atomic absorption spectrometer.Results From 2010 to 2013,the whole blood lead levels of 11 271 children was detected.The mean blood lead levels was 51.0μg/L.The boy lead poisoning rate was higher than girls in different age groups,the difference was statistically significant（P〈0.05）.Both the above indices increased gradually with the increase of age in the range of1-6years old,and the mean blood lead levels reached its peak in preschool age,the mean blood lead did not increased in school-age children,and the lead poisoning rate showed the downward trend.Conclusion The lead poisoning rate of children in Xiamen is close to the average level of other cities,however,the blood lead level tends to increase with the increase of age.The effect of lead pollution on physical health of children shall be paid more attention to nowadays.
