Many of the developed nations have proposed regulations to ban the sale of microbeads in toiletries because of the risk they pose to aquatic and marine environments.
But now it appears that a different type of microplastic is becoming a growing threat to aquatic animals.
Findings of a recent research conducted by scientists from Carleton University, Ontario show that most of the microplastics recovered from the Ottawa River and its tributaries were from microfibers rather than microobeads.
Jesse Vermaire, assistant professor of environmental science, geography and environmental studies at Carleton University said:

What really surprised us is that we found plastic particles in every single water and sediment sample we took, so the plastic was really prevalent in the river system. As much as 95 per cent of the plastic in the water samples collected by Vermaire and the Ottawa Riverkeepers was made up of microfibers. Around five per cent of the plastic was made up of micobeads. A lot of them are coming from synthetic clothing.
Yoga pants, fleece-type jackets, athletic wear and other garments made from synthetic materials contain microscopic plastic fibers — called “microfibers”. Every time you run your washing machine, hundreds of thousands of microfibers are flushed down the drain into natural waterways, eventually reaching the sea and into the food chain.
Ingesting microplastics over a period of time makes animals feel full, meaning many later die of starvation.
Some companies have already started to suggest interim solutions, such as washing synthetics less or capturing the fibers with filters, But a larger, systemic solution, such as new fabric formulations can only be a permanent solution.
