Our clothes generate microplastics that pollute the St. Lawrence River and other bodies of water
AI summary Read the abstract
New research documents an abundance of microplastics in the St. Lawrence River and its estuary, implicating textile washing as a primary source of fiber-shaped plastic particles in this major waterway. The findings are significant because the river serves 45 million people and supports rich biodiversity, meaning widespread microplastic contamination poses risks to both human drinking water quality and aquatic ecosystems at scale.
New research shows an abundance of microplastics in the St. Lawrence River and its estuary, where 45 million people live and is home home to several million animals, invertebrates and plants.

Domestic Washing and Drying as the Source of Microplastics from the Textile and Garments
AI summary Read the abstract
Every time you wash and dry your clothes, tiny plastic fibers break off and escape into the environment, through wastewater into rivers and oceans, and through dryer vents into the air we breathe. This review paper explains that factors like water temperature, fast-fashion fabric quality, and how often you wash your clothes all affect how many of these microfibers are released, and since treatment plants can't fully filter them out, they end up polluting waterways and potentially our food and air. The good news: simple fixes like laundry filters, mesh washing bags, and choosing higher-quality, less frequently washed clothing can help reduce this pollution.
The significant impacts of laundry wastewater on microplastics: a case study in a residential area
AI summary Read the abstract
Researchers measured microplastic concentrations in laundry wastewater from a residential area and tracked their contribution to urban drainage, finding that laundry effluent is a significant and underestimated source of microfibers entering municipal sewer systems and subsequently rivers.
Beyond our oceans: Microplastics pollute rivers and lakes too
AI summary Read the abstract
Researchers and journalists highlighted that microplastic pollution extends well beyond the ocean, contaminating rivers, lakes, and terrestrial ecosystems — environments that supply much of the world's drinking water and food. This broader distribution suggests human exposure to microplastics may be more widespread than previously recognized.
Are Our Synthetic Fabrics Released into the Marine Environment? Evidences on Microplastics Pollution in Wastewater Coming from Our Laundry
AI summary Read the abstract
The MERMAIDS project confirmed that laundry wastewater is a significant vector for synthetic microplastic fibers entering the marine environment, with fiber shedding rates varying by fabric type and washing conditions. Identifying which textile auxiliaries and washing parameters minimize fiber release is a critical step toward reducing this diffuse pollution source.
Impact of Microfiber/Microplastic Pollution
AI summary Read the abstract
Researchers reviewed the growing body of evidence on microfiber and microplastic pollution, finding that textiles, tires, and everyday plastic products release billions of particles into the environment that accumulate in soils, water, and living organisms including humans.
