摘要

本研究旨在评估巴基斯坦拉合尔市过量饮用饮料(果汁、软饮料和能量饮料)对人体健康造成的重金属相关风险。用火焰原子吸收分光光度计(AAnalyst 400-PerkinElmer)测定了17种常用饮料中重金属(Pb、Cr、Co、Cd、Zn、Ni)的浓度(ppm)。根据美国公共卫生协会规定的标准方法制备了一系列标准溶液。据观察，在所有收集的样品(即17个)中，发现某些重金属(即Pb、Cr、Co、Zn和Ni)的浓度接近世界卫生组织、美国环境保护局和巴基斯坦标准质量控制管理局规定的标准允许限度。然而，所有样品都没有任何可检测到的镉浓度水平。

Estimation of toxic metal contamination levels in beverages samples collected from Lahore city in Pakistan.

The present study was conducted to evaluate the risk associated to human health by heavy metals through the intake of beverages (fruit juices, soft and energy drinks) excessively used in city Lahore, Pakistan. The concentration in ppm of heavy metals (Pb, Cr, Co, Cd, Zn and Ni) in 17 popular beverages has been investigated by using Flame Atomic Absorption Spectrophotometer (AAnalyst 400-PerkinElmer). A range of standard solutions were prepared according to the standard methods governed by American Public Health Association. It has been observed that concentration of some heavy metals (i.e Pb, Cr, Co, Zn and Ni) in all collected samples (i.e 17) were found close to the Standard permissible limits provided by World Health Organization, United Sates Environmental Protection Agency, and Pakistan Standards Quality Control Authority. However, all samples were free from any detectable concentration levels of Cd.
