目的:了解六师北塔山牧场学龄前儿童的血铅水平,与新疆五家渠市的同类调查数据进行比对,验证生活环境因素对儿童血铅水平的影响,为治理环境污染,制定预防儿童铅中毒的措施提供科学论据。方法:用奥硕高准度微量元素分析仪对北塔山牧场264名1~6岁的学龄前儿童进行血铅测定,按测定结果≥100ug/L为超标,其中≥200ug/L为铅中毒进行评价,对数据进行统计分析并与五家渠市的同类调查数据进行比对。结果:264例学龄前儿童血铅浓度平均值为29.51±18.36ug/L,血铅超标3例,占比1.14%,无铅中毒者;男童与女童血铅水平无显著差异;但高龄组的血铅水平高于低龄组;白塔山牧场的学龄前儿童血铅水平明显低于五家渠市。结论:北塔山牧场学龄前儿童血铅均值以及血铅超标率均明显低于五家渠市及国内总体水平,生活在污染小的环境中的儿童血铅水平低。
Aims: To understand the blood lead level of preschool children in Beitama Mountain Ranch of the Sixth Division and compare with similar survey data of Wujiaqu City in Xinjiang to verify the impact of living environment factors on blood lead levels in children. In order to control environmental pollution, Lead poisoning measures provide scientific arguments. Methods: The blood lead of 264 preschool children aged from 1 to 6 years in North Tashan ranch was measured by Auschu-based high-precision trace element analyzer. According to the result of determination ≥100ug / L as the standard, ≥200ug / L was the lead poisoning Evaluation, the data were statistically analyzed and compared with similar survey data of five ditch market. Results: The average blood lead concentration in 264 preschool children was 29.51 ± 18.36ug / L, blood lead exceeded 3 (1.14%) and lead poisoning was not found. There was no significant difference in blood lead level among boys and girls Blood lead levels were higher than those in the younger age group; blood lead levels in preschool children in Baita Mountain Range were significantly lower than those in Wujiaqu City. Conclusion: The average blood lead level and the blood lead level in preschool children in Beitashan ranch were significantly lower than those in Wujiaqu City and the overall national level. The blood lead level in children living in a polluted environment was low.
