The study investigated concentrations, distribution, and bioaccumulation of heavy metals in agriculture soil and crops irrigated by the Kali River of Uttar Pradesh, India. Soils and crop samples were collected from 17 locations along the river and analyzed for heavy metal concentrations. Metals in soil and plant were recorded as Fe > Zn > Mn > Cu > Ni > Pb > Cr > Cd and Mn > Fe > Zn > Cu > Cr > Ni > Pb > Cd, respectively. The bioaccumulation factor was < 1 that indicates lesser accumulation of metals in plants except for Cd, Mn, and Zn. Metal pollution index ranged between 1.84 and 6.62 and shows that crops growing at the S₁₀ to S₁₇ sites accumulate greater metal concentrations. Cluster analysis showed agglomeration of Cr-Pb-Cd, Cu-Ni-Mn, and Fe-Zn which revealed different sources of metal pollution. The present study shows low to moderate heavy metal pollution in Kali River irrigated areas thus consumption of agriculture produce may cause adverse health effects.

该研究调查了印度北方邦卡利河灌溉的农业土壤和作物中重金属的浓度、分布和生物积累。从沿河的 17 个地点收集了土壤和作物样本，并分析了重金属浓度。土壤和植物中的金属分别记录为 Fe > Zn > Mn > Cu > Ni > Pb > Cr > Cd 和 Mn > Fe > Zn > Cu > Cr > Ni > Pb > Cd。生物累积因子 < 1，表明除 Cd、Mn 和 Zn 外，植物中金属的累积较少。金属污染指数介于 1.84 和 6.62 之间，表明作物生长在 S ₁₀至 S ₁₇位点积累更大的金属浓度。聚类分析显示 Cr-Pb-Cd、Cu-Ni-Mn 和 Fe-Zn 的团聚，揭示了不同的金属污染源。目前的研究表明，卡利河灌溉地区存在轻度至中度重金属污染，因此食用农产品可能会对健康造成不利影响。
