摘要
目的了解2012年银川市及周边儿童体内血铅含量及相关影响因素,为制定积极有效的干预措施提供科学依据。方法对就诊的1 100名儿童采用钨舟原子吸光度法检测儿童末梢血血铅含量,火焰吸收光度法检测血锌,并对血铅水平影响因素进行分析。结果 1 100名儿童血铅水平均为（38.57±22.02）μg·L-1,铅中毒检出率为1.26%。儿童血铅水平男童较女童高（P〈0.05）;蒙族儿童血铅水平高于汉族、回族,差异有统计学意义（P〈0.05）;居住楼层、住所距车流量大的主要干道、厨房使用燃料等8项是儿童血铅水平增高的主要原因。结论银川市及周边0~6岁儿童铅中毒检出率低于国内其他城市水平,较2004年银川市调查有明显下降,但仍应引起重视,应采取积极、多样的健康宣教等干预措施防治儿童铅中毒。
Objective To understand the Yinchuan city and the surrounding children＇s blood lead levels in the body and related factors in 2012,and provide a scientific basis for the development of positive and effective interventions. Methods 1 100 children were randomly selected in the outpatient children,influencing factors of children＇s blood lead levels were analyzed. Children＇s peripheral blood lead levels were assayed by the tungsten boat atomic absorbance. The serum zinc was determined by the flame atomic absorption spectrophotometry. Results 1 100 children＇s blood lead levels were（ 38. 57 ± 22. 02） μg·L- 1,1. 26% of which were lead-poisoned. There were gender differences and ethnic differences in children＇s blood lead levels. Mongolian children＇s blood lead levels were higher than the Han and Hui. Residential floors,housing from main roads near,kitchen use fuel and so on were the main reason for children＇s blood lead levels. Conclusion The rate of children（ 0- 6 years old） lead- poisoned is lower in Yinchuan city and its surroundings. The levels have decreased significantly compared to the investigation in 2004 in Yinchuan,but we should pay attention to and take positive health education interventions to prevent and treat the lead poisoning in children.
