Heavy metal and pesticide contaminations represent significant environmental and health hazards to humans and animals. Toxic heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), and copper (Cu) persist in the environment, bioaccumulating in beverages and food products from both natural and anthropogenic sources. Traditional remediation techniques, such as chemical precipitation and ion exchange, are effective but often costly and challenging to apply at a large scale. In recent years, grape pomace-a winemaking by-product rich in bioactive compounds-has emerged as a promising, low-cost biosorbent for the removal of such pollutants. Its high adsorption capacity, environmental friendliness, and availability make it a strong candidate for water and food decontamination processes. This study evaluates grape pomace and its biochar as sustainable biosorbents for heavy metal removal from water and soil, examining their adsorption efficiency, adsorption mechanisms, environmental benefits, advantages, limitations, and perspectives for future industrial-scale applications.
重金属和农药污染对人类和动物构成重大的环境和健康危害。铅（Pb）、镉（Cd）、汞（Hg）和铜（Cu）等有毒重金属在环境中持续存在，在天然和人为来源的饮料及食品中生物累积。传统的修复技术，如化学沉淀和离子交换，虽然有效，但成本往往很高，且大规模应用具有挑战性。近年来，葡萄渣——一种富含生物活性化合物的酿酒副产品——已成为一种有前景的低成本生物吸附剂，用于去除此类污染物。其高吸附能力、环境友好性和可得性使其成为水和食品净化过程的有力候选者。本研究评估了葡萄渣及其生物炭作为从水和土壤中去除重金属的可持续生物吸附剂，考察了它们的吸附效率、吸附机制、环境效益、优点、局限性以及未来工业规模应用的前景。
