The tannery industry is a major source of anthropogenic chromium (Cr) contamination due to the large amounts of solid waste produced and its problematic management. The unique composition of tannery waste, usually high concentrations of Cr and other metals as well as organic matter and nutrients, makes it a great risk for soil and water environment but also a possible effective fertilizer for non-food plants that can tolerate metals. The goal of this study was to understand the adaptation mechanism of Salix viminalis to growth on Cr-rich tannery waste from an active landfill. We used a proteomic approach to identify leaf and fine roots proteins altered by tannery waste as compared to control soil conditions. We found no obvious symptoms of oxidative stress in leaves or fine roots. Proteomic results indicated some changes in metabolism, with increases in energy production processes and their greater efficiency for leaves rather than root development. Comparison between S. viminalis and P. × canescens response to tannery waste suggested that S. viminalis is not suitable for remediation of Cr-contaminated areas of a tannery waste landfill site.
制革业是人为铬（Cr）污染的主要来源，因为会产生大量固体废物且管理存在问题。制革废物的独特成分，通常含有高浓度的铬和其他金属以及有机物和养分，这使其对土壤和水环境构成巨大风险，但对于能够耐受金属的非食用植物而言，它也可能是一种有效的肥料。本研究的目的是了解垂柳在来自活跃垃圾填埋场的富含铬的制革废物上生长的适应机制。我们采用蛋白质组学方法来鉴定与对照土壤条件相比，制革废物改变的叶片和细根蛋白质。我们在叶片或细根中未发现明显的氧化应激症状。蛋白质组学结果表明代谢有一些变化，能量产生过程增加，且叶片的效率高于根系发育。垂柳和灰毛杨对制革废物的反应比较表明，垂柳不适合修复制革废物填埋场的铬污染区域。
