【摘要】：目的研究大足地区3~6岁儿童血铅水平及铅中毒的危险因素。方法采用BH2101S型钨舟原子吸收光谱分析仪对本地区8个乡镇幼儿园的3~6岁儿童血铅水平进行检测,同时进行问卷调查,分析不同性别、年龄段及地区3~6岁儿童血铅值及铅中毒发生率,并对升高血铅的危险因素进行筛选。结果 1 393名3~6岁儿童血铅平均值为(54.96±26.81)μg/L,铅中毒儿童772名,中毒率为55.42%,男童血铅水平明显高于女童(P0.05),各年龄段及各地区儿童血铅水平有显著性差异(P0.05),其中以三驱镇3~6岁儿童血铅水平和铅中毒率最高。致使儿童血铅升高的危险因素主要有父母从事工作与铅相关、常接触富铅物品、常进食富铅食物、家庭住房最近装修过,补充锌钙制剂是血铅升高的保护因素。结论重庆大足地区3~6岁儿童血铅水平与中国其他城市相似,需针对致使血铅水平升高的因素采取有效的措施防控铅中毒。
[Abstract]:Objective to study the blood lead level and risk factors of lead poisoning in 3-6-year-old children in Dazu area. Methods BH2101S type tungsten boat atomic absorption spectrometry was used to detect the blood lead level of 3-6-year-old children in 8 township kindergartens in this area. At the same time, a questionnaire survey was conducted to analyze the differences between sexes. The blood lead level and the incidence of lead poisoning in 3-6-year-old children were studied. The risk factors of increasing blood lead were screened. Results the average blood lead level was (54.96 卤26.81) 渭 g / L in 1 393 3-year-old children and 772 lead-poisoned children (55.42%). The blood lead level of boys was significantly higher than that of girls (P0.05). There were significant differences in blood lead levels among children of different ages and regions (P0.05), and the highest blood lead level and lead poisoning rate were found in 3-6-year-old children in Sanqinzhen. The main risk factors leading to the increase of blood lead in children were that their parents were engaged in work related to lead, often exposed to lead-rich articles, often ate lead-rich food, family housing recently renovated, the supplement of zinc and calcium preparations is the protective factor of blood lead elevation. Conclusion the blood lead level of 3-6-year-old children in Dazu area of Chongqing is similar to that of other cities in China. It is necessary to take effective measures to prevent and control lead poisoning according to the factors that lead to the increase of blood lead level.
