项目摘要

Nanomaterials are used in the fabrication of paints, coatings, cosmetics, and many other consumer goods. Many other applications of nanomaterials are expected in the near future, for medical treatment and detection systems, energy production and environmental remediation. It is anticipated that by 2015, the global market for "nano" products will exceed US$1 trillion. Although nanotechnologies promise many social and economic benefits, recent reports published in North America and Europe underline the potential environmental and public health risks linked to this "nano" revolution. A portion of manufactured nanomaterials will end up in the natural environment (e.g., as a result of accidental spills or deliberately introduced for soil and groundwater remediation). As there are no specific regulations to deal with these novel substances, there is an urgent need to better understand the consequences of nanotechnology on environmental health, in order to set protective rules and regulations that do not unjustly penalize Canadian industries. In the interest of fully assessing environmental risk, we need to be able to predict the transport, persistence and bioavailability of engineered nanoparticles in terrestrial ecosystems. This strategic project aims to provide regulators and industries with novel insights and tools needed to assess and predict the transport and transformations of engineered nanoparticles in soils, and to evaluate their toxicity. We propose to evaluate these processes in well-parameterized systems and describe the key mechanisms with mathematical models. The novel data and mechanistic models will greatly improve our understanding of the environmental risks of engineered nanoparticles. We will examine both model conditions but also a large number of Canadian soils of varying properties. The models developed during this project can be linked with multi-criteria decision analysis and environmental risk assessment models. Hence, the knowledge acquired during this project will be of great strategic value to Canadian industries and will provide government agencies like Health Canada and Environment Canada with better decision frameworks and policies to protect human and ecosystem health.
纳米材料用于制造油漆、涂料、化妆品和许多其他消费品。预计在不久的将来,纳米材料还会有许多其他应用,如医疗和检测系统、能源生产和环境补救。预计到2015年,全球纳米产品市场将超过1万亿美元。虽然纳米技术有望带来许多社会和经济效益,但北美和欧洲最近发表的报告强调了与这场“纳米”革命有关的潜在环境和公共卫生风险。一部分人造纳米材料最终将进入自然环境(例如,由于意外溢出或故意引入土壤和地下水修复)。由于没有具体的法规来处理这些新的物质,有迫切需要更好地了解纳米技术对环境健康的后果,以制定保护性的规则和条例,不会不公正地惩罚加拿大的工业。为了充分评估环境风险,我们需要能够预测工程纳米颗粒在陆地生态系统中的运输,持久性和生物利用度。该战略项目旨在为监管机构和行业提供评估和预测工程纳米颗粒在土壤中的运输和转化所需的新见解和工具,并评估其毒性。我们建议在参数化系统中评估这些过程,并用数学模型描述关键机制。 新的数据和机制模型将大大提高我们对工程纳米颗粒环境风险的理解。我们将研究这两个模型条件,但也有大量的加拿大土壤的不同属性。该项目开发的模型可以与多标准决策分析和环境风险评估模型相结合。因此,在该项目期间获得的知识将对加拿大工业具有巨大的战略价值,并将为加拿大卫生部和加拿大环境部等政府机构提供更好的决策框架和政策,以保护人类和生态系统健康。
