目的通过调查顺德大良地区2 285例3~6岁儿童末梢血铅水平,为制定相关公共卫生政策提供依据。方法采集大良2 285例3~6岁儿童末梢血,用电感耦合高频等离子发射光谱法进行血铅检测,并对检测结果进行统计学处理。结果 2 285例学龄前儿童血铅水平为(44.77±17.73)μg/L,铅中毒率1.8%,以轻度铅中毒为主。统计分析显示不同性别儿童铅中毒率比较及城乡间儿童铅中毒率比较,差异均有统计学意义(P<0.05)。男童铅中毒率高于女童(P<0.05);农村儿童铅中毒率高于城镇儿童(P<0.01)。结论重点关注农村地区儿童的铅中毒防治;提高居民环保意识,保障儿童健康成长。
Objective To investigate the level of blood lead in 2 285 children aged 3 ~ 6 years in Daliang, Shunde, so as to provide basis for formulating relevant public health policies. Methods Peripheral blood of 2 285 children aged 3 to 6 years old was collected. The blood lead level was detected by inductively coupled plasma atomic emission spectrometry. The test results were statistically analyzed. Results The blood lead level of 2 285 preschool children was (44.77 ± 17.73) μg / L and the rate of lead poisoning was 1.8%, with mild lead poisoning predominating. Statistical analysis showed that children of different sexes lead poisoning rate comparison and between urban and rural children lead poisoning rates, the differences were statistically significant (P <0.05). The lead poisoning rate in boys was higher than that in girls (P <0.05). The lead poisoning rate in rural children was higher than that in urban children (P <0.01). Conclusions The focus is on prevention and control of lead poisoning among children in rural areas; enhance residents’ awareness of environmental protection and ensure the healthy growth of children.
