Fibers lost during the wear and care of textiles may pose a risk to the environment and human health when released into air and water. A study published in PLOS ONE by Neil J. Lant at Procter & Gamble, Newcastle Innovation Center, Newcastle upon Tyne, United Kingdom, and colleagues suggests that while condenser dryers may reduce airborne microfibers compared to vented dryers, they are a significant contributor of waterborne microfiber pollution.
