The lives of all human beings are dependent on clean air. The World Health Organization (WHO) has estimated that 9 out of 10 humans inhale polluted air, which is responsible for 1 out of 9 deaths globally. Air pollution is linked to ~ 9 million premature deaths. Cities are hot spots for air pollution. Urban atmospheric emissions contribute ~50% to 80% of total global greenhouse gas emissions as well as airborne particles or aerosols, including small nanoparticles, and those consisting of manufactured emerging contaminants. Since air is the fastest moving fluid in the Earth's ecosystem, air pollutants (such as nanoparticles) can be transported to remote regions, such as Arctic. This exciting program goals is to address major uncertainties identified by both the Intergovernmental Panel on Climate Change (IPCC) and the WHO: aerosols, with a focus on smaller nanoparticles, physicochemical processes.  The proposed R&D program is building upon the team's recent world-class discoveries, proposing innovative research, which will establish a new niche for Canada in the domain of airborne nanoparticles and emerging contaminants. It is well-aligned with the government of Canada's strategic development plan, including environment, Arctic, urban development, and sustainable technology. The overarching goal of this research program is to better understand the sources and processes controlling the budget of airborne aerosols and emerging nano-contaminants by developing an innovative approach that will integrate physical and analytical chemistry, with modelling and development of technology, in collaboration with network of partners, to create a decision tool that we foresee can  be incorporated into Canadian air quality models, which are currently used for policy making purposes. It will lead to more effective planning of environmental management measures specifically targeted against air pollution.  The specific R&D themes include: (a) advancing the boundaries of understanding of the physicochemical processes involving airborne nanoparticles, focusing on emerging nano-contaminants, and (b) opening a new era of sustainable technology for atmospheric observation and air pollution remediation. Our objectives will be addressed using a complementary observational, experimental and modelling as well as technology development approach.  This team has the savoir-faire, world-class expertise, cutting edge facilities, to address these important objectives effectively.  We believe that this program is of medium risk and of very high impact potential. This program will conduce a formidable and stimulating multidisciplinary environment to ensure access to state-of-the-art facilities and world-class training of 18 bright HQP per year. These young scientists will obtain their career of their choice to make significant contributions to the Canadian society. They will become future leaders in academia, governmental, industrial, and NGOs, all former ream alumni achieved.

所有人的生命都依赖于清洁的空气。世界卫生组织（世卫组织）估计，每10个人中就有9人吸入污染的空气，全球每9人中就有1人死于污染。空气污染与约900万人过早死亡有关。城市是空气污染的热点。城市大气排放占全球温室气体排放总量的约50%至80%，以及空气中的颗粒或气溶胶，包括小纳米颗粒，以及由制造的新兴污染物组成的颗粒或气溶胶。由于空气是地球生态系统中移动最快的流体，空气污染物（如纳米颗粒）可以被输送到偏远地区，如北极。这个令人兴奋的项目目标是解决政府间气候变化专门委员会（IPCC）和世界卫生组织（WHO）确定的主要不确定性：气溶胶，重点是更小的纳米颗粒，物理化学过程。拟议的研发计划是建立在团队最近的世界级发现的基础上，提出创新研究，这将为加拿大在空气纳米颗粒和新兴污染物领域建立一个新的利基。它与加拿大政府的战略发展计划保持一致，包括环境，北极，城市发展和可持续技术。该研究计划的总体目标是通过开发一种创新方法，将物理和分析化学与建模和技术开发相结合，与合作伙伴网络合作，以更好地了解控制空气中气溶胶和新兴纳米污染物预算的来源和过程，以创建我们预见可以纳入加拿大空气质量模型的决策工具。目前用于政策制定目的。具体的研发主题包括：（a）推进对涉及空气中纳米颗粒的物理化学过程的理解，重点关注新兴的纳米污染物;（B）开创大气观测和空气污染补救的可持续技术新时代。我们的目标将通过互补的观测、实验和建模以及技术开发方法来实现。这个团队拥有娴熟的技能、世界一流的专业知识和尖端的设施，可以有效地实现这些重要目标。我们相信这个项目具有中等风险和非常高的影响潜力。该计划将有助于一个强大的和刺激的多学科环境，以确保获得国家的最先进的设施和世界一流的培训18明亮的HQP每年。这些年轻的科学家将获得他们选择的职业，为加拿大社会做出重大贡献。他们将成为学术界，政府，工业和非政府组织未来的领导者，所有前校友实现。
