Unveiling the Hidden Dangers: How Airborne Microplastics May be Fueling Lung and Colon Cancer

Researchers at UC San Francisco have highlighted a significant environmental health concern: microplastics from tires and degrading garbage are contributing to air pollution, potentially causing a range of serious health issues. A thorough review of around 3,000 studies suggests that these tiny plastic particles—less than 5 millimeters in size—may lead to respiratory problems, male and female infertility, colon cancer, and chronic pulmonary inflammation, which increases the risk of lung cancer.

The study’s senior author, Tracy J. Woodruff, PhD, MPH, emphasizes that microplastics act like particulate matter air pollution, which is known to be harmful. Published on December 18 in the journal Environmental Science & Technology, this research marks the first systematic review of microplastics using methods endorsed by the National Academy of Sciences.

A key source of these airborne plastics is the wearing down of tires and road surfaces from driving. With global plastic production nearing 460 million metric tons annually and projected to double by 2050, the prevalence of microplastics is set to increase.

Most studies reviewed were based on animal models, but researchers believe the findings also apply to humans, due to shared environmental exposures. Building on previous work with the California State Policy Evidence Consortium, the study’s first author, Nicholas Chartres, PhD, calls for regulatory and policy leaders to address the health risks posed by microplastics, particularly regarding colon and lung cancer.

This research not only underscores the need for immediate preventive action but also aims to inform policymakers, urging the adoption of measures to mitigate exposure and protect public health.
