Plastic microbeads, often found in personal hygiene products, are getting rinsed down the drain and ending up in the Great Lakes and other waterways.
To alert customers to these barely visible plastics, a new smartphone App lets consumers scan barcodes to see if a product contains the beads.
The beads are used in many common consumer goods as abrasives, said Sherri A. Mason, an associate professor of chemistry and the program coordinator of environmental sciences at State University of New York–Fredonia.
“They’re also used in boat cleansers and other products as well,” said Mason.
The plastic pollution is simply the result of people washing their faces and brushing their teeth, she said. “It’s an unfortunate reality that people just go to the store and see products that look really cool, like a bottle that has floating beads in a clear liquid,” she said. “They are appealing to the eye from a marketing standpoint but then they wash their face and the beads go down the drain.”
Manufacturers sometimes place the small beads in products to give consumers an exfoliating scrub.
“In personal care products they act to gently scrub away dead skin in much the same way a sponge would,” as listed in Johnson and Johnson’s ingredient policy.
The problem is that wastewater treatment plants are not equipped to filter or break the plastics down, according to Mason.
“Wastewater treatment plants were designed in the 1940s,” Mason said. “A wide variety of pharmaceutical products don’t get removed either, you find these chemicals such as birth control or Ibuprofen. You find various soaps and makeups, things that people use and then they wash down the drain, and the wastewater treatment plant wasn’t used to rid these products from the water.”
Mason doesn’t worry that the tiny plastics are getting into drinking water. That water goes through fabric filtration systems before reaching taps.
It is wastewater that concerns her.
“We have different standards for wastewater than for drinking water,” she said. “We don’t think of the need of cleaning it up to the same degree.”
The plastics can be digested by aquatic life like plankton or zebra mussels and then passed along the food chain to human consumption, Mason said.
The beads can pick up on other pollutants in the water and pass it along to humans, according to the 5 Gyres Institute.
The 5 Gyres Institute, a nonprofit organization that researches plastic pollution in the ocean, recently teamed up with Mason to study how much plastic is accumulating in the Great Lakes.
