| Summary: | Plastic is a general term that refers to a family of organic polymers derived from petroleum sources. In general, plastics are classified as polyester (PET), high-density polyethylene (HDPE), polyvinyl chloride (PVC), low-density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), and others. Plastic pollution is a growing concern because of the high productions of plastics (e.g., 380 million metric tons year−1 in 2015), a wide distribution of plastic debris in the environment, and the adverse effects of plastic ingestion by organisms including humans. Microplastics are defined as plastic fragments with a diameter below 5 mm. They enter the environment in several ways: (1) discharge from wastewater treatment plants; (2) run-off from cities or agricultural lands with sludge applications; and (3) atmospheric transport and deposition. Microplastics are classified as "primary microplastics" which are produced intentionally (e.g., microbeads in personal care products) and "secondary microplastics" which ... : This project will investigate the contamination of microplastics, perfluorinated substances (PFASs) and organophosphate esters (OPEs) in the snow of sub-Arctic and Arctic to improve the understanding of the transport and pathways of these contaminants to the Arctic via atmospheric wet deposition. The objective of this project aims to fulfill the following priorities stated in the 2020-2021 blueprint for the Environmental Monitoring and Research subprogram of the Northern Contaminants Program (NCP): (1) Section 1.4: Identifying plastic and microplastic concentrations in abiotic compartments; Understanding the movement of microplastics to and within the North. (2) Section 7.4.1: Identification and quantification of the transport and deposition of plastics and persistent organic pollutants (POPs) in the Arctic are top priorities for atmospheric monitoring. ... |
