[目的]了解隆昌县铅中毒儿童含量,探讨其综合防治措施以及血铅污染的来源。[方法]以隆昌县鱼建镇金属铅回收厂周围800m以内的1～12岁的424名儿童作为检测对象,以2009年7月～2010年2月泸州医学院附属医院儿科体检的3548名儿童作为参考对象,用原子吸收光谱仪测量其铅含量,计算机统计分析。[结果]隆昌县鱼建镇金属铅回收厂周围800m以内的4岁以下的儿童铅元素含量与对照组比较差异有统计学意义(P﹤0.01),4岁以上的儿童铅元素含量与对照组比较差异具有统计学意义(P﹤0.05),且年龄越小铅中毒阳性率越高。[结论]隆昌县鱼建镇金属铅回收厂周围800m以内的儿童铅元素含量明显高于对照组,且随年龄减少而上升,年龄越小,捡出率越高。应予以足够重视,寻找污染来源,注意环境污染的治理及个人和家庭卫生,保持饮食合理,营养平衡,防治铅重毒给儿童带来的伤害。
[Objective] To understand the content of children with lead poisoning in Longchang County, explore its comprehensive prevention and control measures and the source of blood lead pollution. [Methods] A total of 424 children from 1 to 12 years old within 800m around the Metal Lead Recycling Plant of Yujian Town in Longchang County were selected as the testing objects. From July 2009 to February 2010, 3548 children undergoing physical examination at Affiliated Hospital of Luzhou Medical College As a reference object, its lead content was measured by atomic absorption spectrometry and computerized statistical analysis. [Result] The content of lead in children under 4 years of age within 800m around Yujian Town metal recycling factory in Longchang County was significantly lower than that of the control group (P <0.01). The content of lead in children over 4 years old was significantly lower than that of the control group The difference was statistically significant (P <0.05), and the younger the higher the positive rate of lead poisoning. [Conclusion] The content of lead in children within 800m around Yujian Town metal recycling factory in Longchang County was significantly higher than that in control group, and increased with age. The younger the age, the higher the detection rate was. Due attention should be paid to finding sources of pollution, paying attention to environmental pollution control and personal and family hygiene, maintaining a reasonable diet, balanced nutrition and preventing harm caused by heavy lead poisoning to children.
