Microplastics in Fish Tissue

What’s not known is just how harmful it is to eat these microplastics-in-fish-flesh. But it’s not just the microplastics themselves we’re ingesting: “Microplastics absorb or carry organic contaminants, such as PCBs, pesticides, flame retardants and hormone-disrupting compounds of many kinds, he says.” Another externalized cost of pollution coming back to bite us.

“Researchers do know, however, that microplastics get into aquatic habitats from many different sources, says Chelsea Rochman, an assistant professor of ecology and evolutionary biology at the University of Toronto and co-editor of the report.

“These range from tiny fibres that come off the synthetic fabrics of our clothing, to bits of car tire that wear off on roads and make their way through storm drains into waterways, she says…

“‘The biggest source is likely larger plastic items that we can see during beach cleanups that enter the water and over time break down with the sunlight into smaller and smaller pieces of microplastic.’

“Think plastic bags, styrofoam takeout containers and plastic cutlery, says Rochman…

“‘What we really need to do is a risk assessment … nobody has done that for microplastics.'”
