Atmospheric microplastics: A review of pollution characteristics, human exposure pathways, and emerging health risks

Key Points

• Atmospheric microplastics present significant pollution risks, impacting air quality and human health with increased exposure levels.
• Microplastic pollution in the atmosphere has been documented, with studies showing levels as high as 10,000 particles per cubic meter in urban areas.
• This review assesses the pathways through which humans can be exposed to airborne microplastics, including inhalation and ingestion of particles.
• Understanding the emerging health risks associated with microplastics is crucial, as research suggests potential links to respiratory and cardiovascular issues.
