Abstract

Consumption of heavy metals contaminated dairy milk may affect human health. No such studies have been carried out at the high-altitude region to assess the human health risk after consuming dairy milk. To this end, this study reveals the evaluation of selected heavy metals in dairy milk in the summer and winter seasons, followed by the assessment of heavy metals health risk. Analysis of Jersey crossbred cattle's milk showed that only the zinc level was significantly higher in the summer season. All the non-carcinogenic and carcinogenic parameters were below the permissible limits. However, the carcinogenic risk (CR) level of arsenic and cadmium showed near the threshold level. Based on these findings, it might be concluded that all the studied metals do not have any significant role in health risk. In the near future, CR could be a health concern due to cow milk consumption at a high-altitude region.

摘要

食用受重金属污染的牛奶可能会影响人体健康。在高海拔地区尚未开展此类研究来评估饮用牛奶后对人体健康的风险。为此,本研究揭示了夏季和冬季牛奶中选定重金属的评估情况,随后对重金属健康风险进行了评估。对泽西杂交奶牛的牛奶分析表明,仅夏季的锌含量显著更高。所有非致癌和致癌参数均低于允许限值。然而,砷和镉的致癌风险(CR)水平接近阈值水平。基于这些发现,可以得出结论,所有研究的金属在健康风险方面均无显著作用。在不久的将来,由于在高海拔地区饮用牛奶,致癌风险可能会成为一个健康问题。
