That Fresh Sea Breeze You Breathe May Be Laced With Microplastic

When you stand on a beach and take in a great big gulp of fresh air, you’re actually breathing bacteria, viruses, and aerosolized salts. Those are all punted into the air when whales breach or waves crash or even when bubbles rise to the surface of the sea, ejecting material that gets caught up in sea breezes and fog banks. And as much as I hate to rain on your beach day, you can now add an omnipresent pollutant to that list of debris: microplastics.

When the bubble surfaces, half of it protrudes above the water line, with the other half hidden beneath it. “On the top side out of the water, you've got a very thin layer of water, which when it bursts actually fragments, and that releases nano-sized materials,” says University of Strathclyde microplastic researcher Steve Allen, co-lead on the work.
