In South Asia, the high costs of synthetic fertilizers have imposed research on alternative nutrient inputs. We aimed to identify potential trace elements (PTE) present in some organic manure that might be a source of environmental pollutions and risk to public health following consumption. The study aims to evaluate how different organic waste (poultry waste, PW; press mud, PM; and farmyard manure, FYM) influences the heavy metal migration in soil, the accumulation in garlic, and their potential health risks. Organic waste caused a higher accumulation of certain metals (Zn, Cu, Fe, and Co), whereas Mn, Cd, Cr, and Pb were in lower concentrations in soil. Amendments of soil with PM revealed a higher accumulation of Cd, Cr, Fe, and Pb, whereas PW resulted in Cu and Zn accumulation in garlic. Treatment of soil with FYM exhibited higher metal concentration of Co and Mn. An environmental hazard indices study revealed that pollution load index (PLI) was highest for Cu following treatment with PM. The health risk index (HRI) was greater for Cd following amendment with PM. Maximum daily intake of metals (DIM) was observed for Zn after treatment with PW. The Pb exhibited maximum bioconcentration factor (BCF) in PM-amended plants. Based on these findings, we concluded that garlic grown on contaminated soil with organic waste may pose serious health hazards following consumption.
在南亚，合成肥料的高昂成本促使人们对替代养分投入进行研究。我们旨在确定某些有机肥料中可能存在的潜在痕量元素（PTE），这些元素在被食用后可能成为环境污染源并对公众健康构成风险。该研究旨在评估不同的有机废弃物（家禽粪便，PW；压榨泥，PM；以及农家肥，FYM）如何影响土壤中的重金属迁移、大蒜中的重金属积累及其潜在的健康风险。有机废弃物导致土壤中某些金属（锌、铜、铁和钴）的积累量较高，而锰、镉、铬和铅的浓度较低。用PM改良土壤后，镉、铬、铁和铅的积累量较高，而用PW处理则导致大蒜中铜和锌的积累。用FYM处理土壤后，钴和锰的金属浓度较高。一项环境危害指数研究表明，用PM处理后，铜的污染负荷指数（PLI）最高。用PM改良后，镉的健康风险指数（HRI）更大。用PW处理后，锌的每日最大摄入量（DIM）最高。在PM改良的植物中，铅表现出最大的生物富集系数（BCF）。基于这些发现，我们得出结论，食用在受有机废弃物污染的土壤上种植的大蒜可能会对健康造成严重危害。
