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 understand the content of blood lead in children and provide a scientific basis for the prevention and treatment of lead poisoning in children. Methods A total of 2 850 pediatric children aged 0-14 years from August 2011 to October 2012 in Shenyang Maternal and Child Hospital were analyzed by atomic absorption spectrometry. Results The proportion of blood lead poisoning among 2 850 children of different age groups was 2.67%, 2.74%, 3.12% and 3.15% respectively. The proportion of blood lead poisoning increased slightly with age. However, there was no significant difference among all age groups (χ2 = -0.15, P> 0.05). There were 2 769 cases of blood lead <100 μg / L, 81 cases of mild blood lead poisoning and 2.85% lead poisoning, the difference was statistically significant (χ2 = 10.15, P <0.05). Conclusion Blood lead content increased with age, and the prevalence of lead poisoning in boys was higher than that in girls. Proposed early detection, early diagnosis and early treatment to ensure the healthy growth of children.
