Blood lead toxicity has been prominently related to vehicular emissions. The lead is a carcinogenic metal systematically damages bones and central nervous system. The present investigation is focused on likely impacts of environmental and socioeconomic factors on the concentration of blood lead levels in children. The findings of the study show that the highest blood lead levels were observed in the age group of 4-8 years (5.46 μg/dl) with mother's education having an inverse proportionality with the blood lead levels of children. Furthermore, children belonging to families with income (> 100,000) exhibited the highest blood lead levels (5.52 μg/dl) than the rest of the categories which was further advocated by lower blood lead levels in children residing in better residential conditions. High proximity of school to highway distance seemed to play a vital role in the concentration of lead in children while the traffic flow density was observed to have proportionality effect on the blood lead levels. From the study, it is concluded that 28% of the children in the sample population were having lead levels above the permissible limits as per Centre for Disease Control and Prevention. The study reflects the alarming toxicity of lead in children residing in a non-industrial region which further gives rise to concerns about the health of the children residing in industrialized regions of the world with high lead levels in the environment.
血铅毒性与机动车排放密切相关。铅是一种致癌金属,会对骨骼和中枢神经系统造成系统性损害。本研究重点关注环境和社会经济因素对儿童血铅浓度的可能影响。研究结果表明,血铅水平最高的是 4-8 岁年龄组(5.46μg/dl),母亲的教育程度与儿童血铅水平呈反比。此外,收入超过 10 万的家庭的儿童血铅水平最高(5.52μg/dl),高于其他类别,而居住条件较好的儿童血铅水平较低,这进一步证实了这一结果。学校与高速公路的距离较近似乎对儿童体内铅浓度起着至关重要的作用,而交通流量密度对血铅水平则呈比例关系。研究表明,在抽样人群中,28%的儿童血铅含量超过了疾病控制与预防中心规定的允许限度。本研究反映了非工业化地区儿童铅中毒的严重程度,这进一步引起了人们对世界工业化地区儿童健康的担忧,因为这些地区环境中的铅含量很高。
