Microplastics Found in Dolphin Breath, Indicating New Exposure Route

A groundbreaking study reveals that dolphins are inhaling microplastics, raising concerns about potential health impacts on marine life.

Researchers detected microplastic particles in the exhaled breath of bottlenose dolphins from Florida and Louisiana, marking the first evidence of inhalation exposure in these marine mammals.
The study, published in PLOS ONE, found that all 11 dolphins tested had at least one microplastic particle in their breath, including fibers and fragments of various plastic polymers.
Microplastics, often associated with clothing materials like polyester, are widespread in the environment and have been linked to health issues such as lung inflammation in humans.
The findings highlight the pervasive nature of microplastic pollution, as particles were found in dolphins from both urban and rural areas, suggesting widespread airborne contamination.
Further research is needed to understand the full impact of inhaled microplastics on dolphin health, with potential parallels to known respiratory issues in humans.
