项目摘要

PROJECT 1 – ENVIRONMENTAL PROJECT 1 – EP1 - PROJECT SUMMARY Environmental Project 1 will make use of ubiquitous resources both by geochemically customized immobilization strategies making use of existing minerals in mine wastes, as well as exploiting bioaccumulation patterns from local plant root systems. Biogeochemical and mass transfer interfacial processes will be investigated through bench scale experiments using field sediment samples, integrating aqueous chemistry, molecular environmental microbiology, mathematical models, advanced microscopy, and spectroscopy tools. We hypothesize that ubiquitous mineral phases and plants can be used to immobilize metal mixtures under surface oxidizing conditions. Environmental Project 1 will have an invaluable impact on the Pueblo and Navajo communities that live in the proximity of abandoned mine wastes sites. Through the integration of advanced techniques at the cutting- edge of environmental science and engineering, we will investigate reactions and mechanisms at the molecular level to understand macro-scale processes. We will engineer phytoremediation strategies using biogeochemistry tools and reactive transport modeling, together with Next Generation Sequencing analyses (metagenome for rhizosphere experiments). We will use a combination of in-vitro and greenhouse experiments to define specific phytoremediation approaches to decrease metal contamination in soils which will be tested in pilot studies. The participating Pueblo and Navajo communities and UNM METALS scientists will produce new knowledge that can be applied to thousands of other existing abandoned mine waste sites.

项目1 - 环境项目1 - EP1 - 项目摘要环境项目1将通过地球化学定制使用无处不在的资源固定策略利用矿井中现有的矿物质以及利用生物蓄积的策略来自当地植物根系的模式。生物地球化学和传质界面过程将是通过使用田间沉积物样品进行的基准规模实验研究，整合水性化学，分子环境微生物学，数学模型，高级显微镜和光谱工具。我们假设无处不在的矿物相和植物可用于将金属混合物固定在下面表面氧化条件。环境项目1将对生活在Pueblo和Navajo社区中产生无价的影响靠近废弃的矿石遗址。通过将高级技术的整合在剪裁处环境科学与工程的边缘，我们将调查在分子水平了解宏观尺度过程。我们将使用生物地球化学工具和反应性传输建模，以及下一代测序分析（用于根际实验的元基因组）。我们将结合体内和温室定义特定植物修复方法以减少土壤中金属污染的实验将在试点研究中进行测试。参与的Pueblo和Navajo社区以及UNM金属科学家将产生可应用的新知识，可应用于其他数千个现有的废弃矿石废物。
