用电感耦合等离子体质谱仪测定了顺德杏坛地区城乡间共600名0～6岁儿童的血铅含量,并对血铅水平及高血铅率进行了统计分析。结果表明,受测儿童的平均血铅水平为68.79μg/L,高血铅率为13.33%。城乡间儿童血铅水平和高血铅率均存在显著差异,城镇儿童血铅水平为79.19μg/L,高血铅率为16.67%;农村儿童血铅水平为58.38μg/L,高血铅率为10.00%。同一地区不同性别间的血铅水平和高血铅率则无显著差异。
The blood lead levels of 600 children aged 0-6 years in urban and rural areas in Shunde district were measured by inductively coupled plasma mass spectrometry. The blood lead levels and blood lead levels were also analyzed. The results showed that the average blood lead level of children tested was 68.79μg / L, and the rate of high blood lead was 13.33%. Blood lead levels and high blood lead rates in urban and rural children were significantly different, the level of lead in urban children was 79.19μg / L, the rate of high blood lead was 16.67%; the level of lead in rural children was 58.38μg / L, the rate of high blood lead Is 10.00%. There was no significant difference in blood lead levels and blood lead levels among different sexes in the same area.
