目的了解深圳市学龄前儿童的血铅水平,为制定积极有效的干预措施提供科学依据。方法对13 851例0～6岁儿童采集静脉血,用BH2100型原子吸收光谱法测定血铅水平。结果 13 851名儿童血铅均值为47.87μg/L,铅中毒发生率2.642%。血铅水平随年龄递增,总体有差异(P<0.05),各年龄组铅中毒发生率总体差异无统计学意义,男女性别间差异无统计学意义。结论深圳市儿童血铅水平处于低水平,但仍需加强血铅控制。
Objective To understand the blood lead levels of preschool children in Shenzhen and to provide a scientific basis for making active and effective interventions. Methods Venous blood samples were collected from 13 851 children aged 0-6 years. Blood lead levels were determined by BH2100 atomic absorption spectrometry. Results The average blood lead level of 13 851 children was 47.87 μg / L, and the incidence of lead poisoning was 2.642%. Blood lead levels increased with age, there was a difference (P <0.05). There was no significant difference in lead poisoning incidence among all age groups. There was no significant difference between male and female gender. Conclusion Children’s blood lead levels in Shenzhen are low, but blood lead control still needs to be strengthened.
