ANR-Biological filtration to reduce trace elements in woody biomass

在法国和加拿大，由于工业活动，存在大量被微量元素（TE）高度污染的场地，对环境和人类健康造成危害。该提案旨在制定短期和长期轮换战略，以覆盖TE污染土地，并将其重新转化为生产力和复原力强的生态系统，提供各种商品和服务。它还将评估通过选择避免TE从土壤大量转移到可收获的木质生物质的品种或品种来生产木质生物质的可能性。短期和长期的研究目标是：i）开发基于候选基因方法的功能基因组标记，以辅助树木和微共生体物种的基因型选择; ii）选择（在体外和体内）对污染土壤中遇到的TE具有生态遗传耐受性的树木和微共生体物种; iii）建立和评估基于间作树种的综合生物修复大规模实地试验; iv）对这些试验进行经济和财务分析以及社会接受度分析;以及v）协调、沟通和传播结果和信息。该项目的创新方面依赖于技术和经济可行性水平。为了解决与这些创新方面相关的复杂问题，我们组建了一个由两国领先科学家组成的法国-比利时联盟，他们具有互补的专业知识。开发这种潜在的补救生物技术将为两国的辅助工业和环境咨询机构提供机会。该联合研究项目是NSERC加强与ANR-法国科学合作的国际战略的一部分，它将加强两国研究和创新界之间的合作，以取得世界级的科学和技术成果，从而在健康环境和生态系统领域实现新的创新绿色技术。它也符合大学的研究和培训任务，并与NSERC的使命投资于人，发现和创新，可以强烈影响加拿大的绿色经济，社会和/或环境在未来10年内。

Due to industrial activities, large sites highly contaminated by trace elements (TE) are present in France and Canada, imposing hazard(s) to environment and human health. This proposal aims at developing a short and long rotation strategy for the capping of TE contaminated lands and for reconverting them into productive and resilient ecosystems offering a full range of goods and services. It will also evaluate the possibility of producing woody biomass by selecting cultivars or varieties that avoid mass translocation of TE from soil to the harvestable woody biomass. The short-and long- term research objectives are to: i) develop functional genomic markers based on candidate genes approach to assist genotypic selection of tree and microsymbiont species; ii) select (in vitro and in vivo) ecogenetically tolerant tree and microsymbiont species to TE encountered in contaminated soils; iii) establish and evaluate integrated bioremediation large-scale field trials based on intercropping tree species; iv) conduct economical and financial analyses and social acceptance of these trials; and v) coordinate, communicate and disseminate the results and information. The innovative aspects of this project rely on both technological and economical feasibility levels. To address the complex questions related to these innovative aspects, we have assembled a Canadian-French consortium of leading scientists in both countries with complementary expertise. Exploitation of this potential remediation biotechnology will provide opportunities for ancillary industries and environmental consultant agencies in both countries. This joint research project is part of NSERC's international strategy to increase scientific collaboration with the ANR-France, It will strengthen the collaboration between the two countries' research and innovation communities to achieve world-class scientific and technical results, leading towards new innovative green technologies in the area of healthy environment and ecosystems. It is also consistent with the University's research and training mandates and with NSERC's mission to invest in people, discovery and innovation that could strongly influence Canada's green economy, society and/or environment within the next 10 years.
