Phytoextraction approaches for mitigating heavy metal release from unlined and loosely capped rural landfills

澳大利亚农村的垃圾填埋场用于储存含有有毒金属的危险废物。通常使用不透水的粘土盖来封装这些废物，防止污染物释放到环境中。这些瓶盖的完整性是至关重要的，需要不断的照顾。该项目旨在开发新的方法，大大改善农村垃圾填埋场的长期环境安全，并带来额外的经济效益。这些方法涉及使用高价值的树木作物和能够提取有毒金属的植物。这些植物的利用将在一个原本不发达的地区创造一种宝贵的资源，这将具有相当大的地方/区域利益和国家意义。

Australian rural landfills are used for storing hazardous wastes which contain toxic metals. Impermeable clay caps are often utilized to encapsulate these wastes and prevent release of pollutants into the environment. The integrity of these caps is crucial and requires constant care. The project aims to develop novel approaches which will improve substantially the long-term environmental safety of rural landfills and deliver additional economic benefits. These approaches involve the use of high-value tree crops and plants capable of extracting toxic metals. Utilization of these plants will create a valuable resource on an otherwise derelict area and this will be of considerable local/regional benefit and national significance.
