Scientists have been worried about the potential harms of microplastics for years. These small plastic particles less than 5 mm in length have been found everywhere because of plastic pollution – from the Earth’s deep oceans to remote regions in Antarctica, and even the seafood we eat. But, are microplastics really harmful?
Microplastics are tiny pieces of plastic that are microscopic and up to 5 millimetres in size. McGill research project aims to provide an understanding of how these contaminants end up in Canadian aquatic environments and what impacts they have.
A team of researchers from McGill University and the Quebec government have discovered microplastics (in the form of polyethylene 'microbeads,' less than 2 mm in diameter) widely distributed across the bottom of the St. Lawrence River, the first time such pollutants have been found in freshwater sediments.
