重金属，如铅，镉，铜，锌的浓度已确定通过使用差分脉冲阳极溶出伏安法（DPASV）在空气颗粒物，饮食，儿童的血液居住在不同位置的蒂鲁帕蒂。通过对各种标准物质的分析，验证了DPASV技术测定环境和生物样品中Pb、Cd、Cu、Zn的可靠性。儿童吸入铅、镉、铜、锌的日摄入量分别为0.1014 ~ 0.3264、0.0204 ~ 0.0372、0.1953 ~ 0.3310、76.1902 ~ 78.3720 μ g·d（-1）;经膳食摄入量分别为954.92 ~ 1264.70和5750.14 ~ 6774.56 μ g·d（-1）。铅，镉，铜，锌在儿童的血液中的保留时间估计这些金属在空气中的颗粒物和复制的饮食和血液的儿童。Pb、Cd、Cu和Zn的平均保留时间分别为17.32、7.85、2.12和1.92天。
Concentrations of heavy metals such as Pb, Cd, Cu, and Zn have been determined by using differential pulse anodic stripping voltammetry (DPASV) in air particulates, diet, and children's blood residing at different locations of Tirupati. The reliability of the procedure for estimation of Pb, Cd, Cu, and Zn in environmental and biological samples by DPASV technique was checked by analyzing various standard reference materials. The observed daily intake of Pb, Cd, Cu, and Zn by children varies from 0.1014 to 0.3264, 0.0204 to 0.0372, 0.1953 to 0.3310, and 76.1902 to 78.3720 mu g day(-1) through inhalation, and 17.53 to 20.91, 1.92 to 2.32, 954.92 to 1264.70, and 5750.14 to 6774.56 mu g day(-1) through dietary intake, respectively. Retention times of Pb, Cd, Cu, and Zn in children's blood are estimated by using levels of these metals in air particulates and by duplicating diet and blood of children. The observed average retention times for Pb, Cd, Cu, and Zn are 17.32, 7.85, 2.12, and 1.92 days, respectively.
