New Electroosmotic Pulse Process for Phytoremediation

描述（由申请人提供）：在美国，有毒金属释放到环境中与大约1%的癌症病例直接相关，并导致1320万美元的医疗费用。与向环境中排放有害金属有关的其他与健康有关的影响包括心血管和冠心病、新生儿死亡风险增加、中风和高血压。面对所有这些问题，迫切需要精确地修复这些地点，防止进一步不受控制地释放到环境中。这个SBIR项目的最终目的是展示一种新的土壤修复和清理方法，通过结合电动力学和植物修复来浓缩，然后生物积累有毒重金属污染物。植物修复是一种利用植物去除、控制或使环境污染物无害的新技术。这项拟议的技术使用Lynntech的电动技术将金属污染物动员到根区（根际），在那里它们可以在植物生长过程中积累。在第一阶段，Lynntech将在一系列现场后测试平台中演示该技术，然后在马里兰州Fort George Meade进行为期14个月的现场演示。在第二阶段，Lynntech将扩展第一阶段获得的信息，并进行全面的现场净化研究。

DESCRIPTION (provided by applicant): The release of toxic metals into the environment has been directly linked to approximately 1% of cancer cases in the United States and has resulted in medical costs of $13.2 million. Other health-related effects that have been connected with the discharge of hazardous metals into the environment include cardiovascular and coronary heart disease, increased risks for neonatal mortality, strokes, and hypertension. With all of these problems, there is an urgent need to accurately remediate these sites and prevent further uncontrolled release to the environment. The ultimate aim of this SBIR project is to demonstrate a new approach to soil remediation and cleanup by using a combination of electrokinetics and phytoremediation to concentrate, then bioaccumulate toxic heavy metal contaminants. Phytoremediation is a new technology that uses plants to remove, contain, or render harmless, environmental contaminants. This proposed technology uses Lynntech's electrokinetic technology to mobilize metal contaminants into the root zone (rhizosphere) where they can be accumulated in the plants as they grow. In Phase I, Lynntech will demonstrate this technology in a series of post-field test beds before performing a 14-month field demonstration at Fort George Meade, MD. In Phase II, Lynntech will expand on the information gained in the Phase I and perform a full-scale site decontamination study.
