为探讨电子垃圾处理区域居民体内丙二醛和铁、锌、钙、镁含量的相关性及对人体健康的影响。于2011年3月选取华北地区某市A县电子垃圾处理区域32名从事电子拆解作业职业的居民(职业组)和31名不从事拆解作业的居民(暴露组)及55名居住于距离该地50 km的居民(对照组),检测外周血中铁、锌、钙、镁的含量及血清中丙二醛含量。结果显示以人群的性别和年龄为协变量进行方差分析,职业组和暴露组外周血铁、锌、钙、镁含量均低于对照组(P<0.01),丙二醛含量高于对照组(P<0.01),外周血铁、锌、钙、镁含量均与丙二醛含量呈负相关(P<0.05)。提示居住在电子垃圾拆解地的居民体内铁、锌、钙、镁缺乏,丙二醛含量增多,体内氧化应激反应增强。
To investigate the correlation between malondialdehyde (MDA) and iron, zinc, calcium and magnesium in residents in the electronic waste treatment area and its impact on human health. In March 2011, 32 residents engaged in electronic dismantling operation (occupational group) and 31 residents (exposure group) not engaged in dismantling operation were selected from the electronic waste disposal area in A county of a city in North China and 55 residents living in distance The population of 50 km in this area (control group), the detection of peripheral blood iron, zinc, calcium, magnesium and serum malondialdehyde content. The results showed that gender and age of the population were used as covariates for analysis of variance. The levels of iron, zinc, calcium and magnesium in the peripheral blood of the occupational group and the exposed group were lower than those of the control group (P <0.01) and the content of malondialdehyde was higher than that of the control group P <0.01). The levels of iron, zinc, calcium and magnesium in peripheral blood were negatively correlated with the content of malondialdehyde (P <0.05). It is suggested that the inhabitants living in the dismantling of electronic rubbish lack iron, zinc, calcium and magnesium, the content of malondialdehyde increased, and the in vivo oxidative stress reaction increased.
