Canadian and international concern is mounting regarding risks associated with microplastic (MP) ubiquity, accumulation and potential for ingestion. In response, federal and municipal strategies have been proposed to reduce plastic waste, support a circular economy, and mitigate MP pollution in the environment. A key road block to efficient policy implementation remains the knowledge gap in MP sources, transport, and fate, limiting our capacity to track and remove those already in the environment. A lack of consistent analytical methods has restricted data comparability across studies. These gaps constrain our ability to use models, which help to identify source contributions and sustainable control measures, and which are needed to support policy and management initiatives. This program addresses these gaps by using novel approaches to generate the knowledge, tools and data required to establish effective control strategies. We will develop new tools for high resolution sample analysis. We will harmonise novel and existing analytical procedures across instruments, institutions, and across air, soil and water, to establish an MP surveillance network. This will build knowledge of sources, pathways and distribution of MPs across Ontario. We will use these tools and data to identify MP sources in remote areas (e.g. Canadian Arctic) and to calibrate watershed models. These will be used to quantify control measure effectiveness, based on experimental assessments of available technologies. Models, data, and operating procedures will be made available through a new online MP database, ensuring that this program acts as a resource to support existing and future research programs e.g. the Arctic Monitoring and Assessment Program. By working directly with municipal and federal stakeholders, and engaging with diverse groups of stakeholders, knowledge developed through this program will be directly applied to support effective MP mitigation policies which can be used across Canada.

加拿大和国际社会越来越关注与微塑料 (MP) 的普遍存在、积累和摄入潜力相关的风险。为此，联邦和市政府提出了减少塑料废物、支持循环经济并减轻塑料对环境污染的战略。高效政策实施的一个关键障碍仍然是MP来源、运输和命运方面的知识差距，限制了我们追踪和清除环境中已经存在的MP的能力。缺乏一致的分析方法限制了研究之间的数据可比性。这些差距限制了我们使用模型的能力，而模型有助于确定源贡献和可持续控制措施，也是支持政策和管理举措所必需的。该计划通过使用新颖的方法来生成建立有效控制策略所需的知识、工具和数据来解决这些差距。我们将开发用于高分辨率样品分析的新工具。我们将协调跨仪器、机构以及跨空气、土壤和水的新颖和现有分析程序，以建立 MP 监测网络。这将建立有关安大略省议员来源、途径和分布的知识。我们将使用这些工具和数据来识别偏远地区（例如加拿大北极）的 MP 源并校准流域模型。这些将用于根据现有技术的实验评估来量化控制措施的有效性。模型、数据和操作程序将通过新的在线 MP 数据库提供，确保该计划作为支持现有和未来研究计划的资源，例如：北极监测和评估计划。通过直接与市和联邦利益相关者合作，并与不同的利益相关者群体合作，通过该计划开发的知识将直接应用于支持可在加拿大各地使用的有效的 MP 缓解政策。
