目的:了解锡山地区学龄前儿童末梢全血中铅、镉水平,为采取积极有效的铅、镉中毒防治措施提供依据。方法:采用北京普析通用仪器公司生产的MG2型石墨炉原子吸收分光光度计(血液铅镉分析仪)测定锡山区3～7岁儿童末梢全血中铅、镉水平。结果:锡山区3～7岁学龄前儿童末梢全血中有6.80%的儿童血铅水平超过100μg/L的相对安全范围;有3.13%儿童血镉水平超过0.3～1.2μg/L的相对安全范围;不同性别组儿童血中铅、镉水平超标无统计学差异。结论:任何程度的铅、镉污染均对儿童健康有损害,因此铅、镉损伤的防治应从保护健康与健康促进角度提出早期预防,加强健康教育与非药物驱铅、驱镉,以使儿童免受铅、镉污染的损伤。采用MG2型石墨炉原子吸收分光光度计(血液铅镉分析仪)测定儿童末梢全血中铅、镉含量,具有需血量少、简便快速、准确性高、污染小等优点,适合进行大规模的普查。
Objective: To understand the lead and cadmium levels in peripheral blood of preschool children in Xishan area, and to provide a basis for the prevention and cure measures of lead and cadmium poisoning. Methods: The level of lead and cadmium in peripheral blood of 3 ~ 7 years old children in Xishan district was determined by MG2 graphite furnace atomic absorption spectrophotometer (blood lead and cadmium analyzer) manufactured by Beijing PuGe General Instrument Company. Results: The relative safety range of blood lead levels of more than 100 μg / L was found in 6.80% of peripheral blood of preschool children aged 3-7 years old in Xishan District; 3.13% of children had a relative safety range of more than 0.3-1.2 μg / L There was no significant difference in blood lead and cadmium levels among children of different genders. Conclusion: Any level of lead and cadmium pollution are harmful to children’s health. Therefore, the prevention and treatment of lead and cadmium injury should put forward early prevention from the point of health protection and health promotion, and strengthen health education and non-drug drive lead and cadmium drive so that children By lead, cadmium pollution damage. The determination of lead and cadmium in peripheral blood of children by MG2 graphite furnace atomic absorption spectrophotometer (blood lead-cadmium analyzer) has the advantages of less blood requirement, simple and quick, high accuracy and small pollution, and is suitable for large-scale Census
