The rapid growth and widespread use of plastics materials in modern societies, combined with inadequate recycling practices, has resulted in the accumulation of small plastic fragments in the environment known as microplastics. The knowledge of microplastics occurrence in freshwater systems in Canada is presently very limited, especially in western Canada. The project aims to establish a correlation between microplastics occurrence and: 1) freshwater quality parameters, and 2) urban and industrial inputs along the North Saskatchewan River (NSR) within the Edmonton Municipal Region. The data generated from this work will help establish a baseline of microplastics occurrence in the region and will directly measure the impact of our industry partners, Dow Chemical Canada and Inter Pipeline, who operate major plastics manufacturing facilities discharging into the NSR. A key deliverable of this project is the development, optimization and validation of methods suitable for rapid adoption by industry related to the collection of surface water; the isolation of microplastics from these samples; and their analysis using a high-throughput technique. This project aligns with Canada's Plastics Science Agenda and will provide unbiased, evidence-based information about the presence and typology of microplastics in freshwater systems. The results from this work will directly benefit the industry partners through data describing their environmental impact, the environmental consultancy community through access to knowledge about accurate and high-throughput methods for microplastics sample collection and analysis, and all levels of Government and the public who will be able to access useful data for public health policy development.

在现代社会中塑料材料的快速生长和广泛使用，再加上回收实践不足，导致了被称为微塑料的环境中小型塑料碎片的积累。目前，加拿大淡水系统中微塑料发生的知识非常有限，尤其是在加拿大西部。该项目旨在建立微塑料发生之间的相关性和：1）淡水质量参数，以及2）埃德蒙顿市政区北萨斯喀彻温省河（NSR）沿北萨斯喀彻温河（NSR）的城市和工业投入。这项工作产生的数据将有助于在该地区建立微塑料发生的基线，并将直接衡量我们的行业合作伙伴，道琼斯工业卫生加拿大陶氏化学和Inter Pipeline的影响，他们经营着出排入NSR的主要塑料制造设施。该项目的一个关键可交付是适用于与地表水收集有关的行业快速采用的方法的开发，优化和验证；从这些样品中分离微塑料；以及他们使用高通量技术的分析。该项目与加拿大的塑料科学议程保持一致，并将提供有关淡水系统中微塑料的存在和类型的公正的基于证据的信息。这项工作的结果将通过描述其环境影响，环境咨询社区的数据直接使行业合作伙伴受益匪浅，通过获取有关微塑料采样和分析的准确和高通量方法的知识，以及所有级别的政府和公众，他们将能够访问有用的公共卫生政策发展数据。
