Microplastics have become ubiquitous, showing up everywhere from human blood to Arctic Sea ice
Fillets from fish caught along Toronto ’s waterfront have up to 12 times more microplastics per serving than some common store-bought alternatives, newly published research suggests.
Microplastics, no bigger than the width of a pencil eraser down to about the width of mitochondria, have become ubiquitous, showing up everywhere from human blood to Arctic Sea ice. In fish, these broken-down bits of larger plastics have been linked to lower levels of growth and reproduction, among a suite of other issues.
Madeleine Milne, co-author of the latest study, said the results show how microplastic pollution has become a “pervasive environmental issue.” “I think it’s promising. I think we just need to kind of understand why this is happening,” said Milne, who is now a graduate student at the University of Manitoba.
Fillets still pale in comparison to some other common ways humans are exposed to microplastics, the study noted. The authors estimated someone who ate two servings of Humber Bay fish fillets per week would ingest about 12,800 particles a year, compared to about 90,000 particles a year from bottled water.
