摘要
目的了解儿童体内血铅的含量,为儿童铅中毒的防治提供科学依据。方法采用原子吸收光谱法,对沈阳市妇婴医院2011年8月至2012年10月儿科门诊2 850例0～14岁儿童进行铅测定。结果 2 850例儿童中不同年龄组血铅中毒比例分别为2.67%、2.74%、3.12%和3.15%,血铅中毒比例随年龄增长略有增加。但各年龄组间比较差异无统计学意义(χ2=-0.15,P>0.05)。其中血铅<100μg/L为2 769例,血铅轻度中毒81例,铅中毒率为2.85%,差异有统计学意义(χ2=10.15,P<0.05)。结论血铅含量随着年龄增长在增多,男童铅中毒比例高于女童。建议早发现,早诊断,早治疗,以确保儿童健康成长。
Objective To investigate children′s blood lead levels,and provide a scientific basis for the prevention and treatment of lead poisoning in children.Methods The blood 1ead concentrations of 2 850 children from pediatric outpatient clinic were determined using atomic absorption spectrophotometer from August 2011 to October 2012.Results Among the 2 850 children,the blood lead poisoning rate in different age groups was 2.67%,2.74%,3.12% and 3.15%,respectively.The lead poisoning rate was increasing slightly along with the age growth.There were no statistical differences among different age groups(χ2=-0.15,P>0.05).There were 2 769 cases with blood lead concentration < 100 μg/L,81 cases of blood lead mild poisoning,with a lead poisoning incidence of 2.85%.The differences had statistical significance(χ2=10.15,P<0.05).Conclusion The blood lead levels are increasing with age;the lead poisoning ratio in boys is higher than in girls.Early detection,diagnosis and treatment are suggested in order to ensure the health and growth of children.
