Abstract

Delhi’s agricultural hub, nestled along the Yamuna floodplains, faces soil and water contamination issues. Utilizing organic waste composts is gaining traction to improve soil quality, but uncertainties remain about their efficacy in reducing harmful elements. The study examined three Amaranthaceae cultivars, comparing organic waste composts with chemical fertilizer to evaluate correlations between heavy metals, antioxidants, and antinutrients to assess their bioremediation potential. “Heavy metals” or “potentially toxic elements (PTE)” levels in soil and leaves were measured by ICP-MS, while antioxidants and antinutrients were analyzed with UV–VIS spectroscopy. The study revealed higher PTE levels in floodplain soil, with Cr, Ni, and Cd exceeding safe limits in all cultivars. Compost amendments reduced these pollutants by 28% compared to chemical fertilizers, decreasing bioaccumulation by 20%. Health risk assessments showed lower risks in compost-amended cultivars. Additionally, compost amendment displayed a stronger negative correlation between PTE and antioxidants, suggesting effective bioremediation. Overall, compost amendments offer promise for mitigating PTE in metropolitan floodplains.

苋科作物中潜在有毒元素积累的健康风险评估及其与抗氧化剂和抗营养素的相关性。

德里的农业中心坐落在亚穆纳河洪泛区，面临着土壤和水污染问题。利用有机废物堆肥来改善土壤质量的做法正日益受到重视，但其在减少有害元素方面的功效仍存在不确定性。这项研究考察了三个苋科栽培品种，比较了有机废物堆肥和化肥，评估了重金属、抗氧化剂和抗营养素之间的相关性，以评估它们的生物修复潜力。土壤和叶片中的 "重金属 "或 "潜在有毒元素（PTE）"含量是通过 ICP-MS 测量的，而抗氧化剂和抗营养素则是通过 UV-VIS 光谱分析的。研究发现，洪泛区土壤中的 PTE 含量较高，所有栽培品种中的铬、镍和镉含量都超过了安全限值。与化肥相比，堆肥添加剂可将这些污染物减少 28%，生物蓄积性降低 20%。健康风险评估结果表明，堆肥改良后的栽培品种风险较低。此外，堆肥改良剂在 PTE 和抗氧化剂之间显示出更强的负相关性，表明生物修复效果显著。总之，堆肥改良剂有望减轻大都市洪泛区的 PTE。

期刊介绍： Archives of Environmental Contamination and Toxicology provides a place for the publication of timely, detailed, and definitive scientific studies pertaining to the source, transport, fate and / or effects of contaminants in the environment. The journal will consider submissions dealing with new analytical and toxicological techniques that advance our understanding of the source, transport, fate and / or effects of contaminants in the environment. AECT will now consider mini-reviews (where length including references is less than 5,000 words), which highlight case studies, a geographic topic of interest, or a timely subject of debate. AECT will also consider Special Issues on subjects of broad interest. The journal strongly encourages authors to ensure that their submission places a strong emphasis on ecosystem processes; submissions limited to technical aspects of such areas as toxicity testing for single chemicals, wastewater effluent characterization, human occupation exposure, or agricultural phytotoxicity are unlikely to be considered.
