Researchers have found microplastics in the most remote places on Earth and have investigated their accumulation in our food.

But what are the health effects on human health after ingestion or exposure to these particles? Scientists are investigating.

It’s still unclear what the environmental and health impacts of microplastics could be, according to a news release from the American Chemical Society.

Indeed, as Prof Mark Taylor of Macquarie University in Sydney told The Guardian last year, “nobody really knows”. However, as he stressed, “absence of evidence is not evidence of absence”.

But, there’s research ongoing, according to the American Chemical Society, although lots more work is needed if we’re to understand the effects. A Nature news feature in May 2021 explained that the first step underway at the moment is understanding levels of exposure.

For example, in California, work is underway to test and report levels of microplastics in drinking water.
