Microplastics Linked to Lung and Colon Cancer

Long-term exposure to microplastics links to increased risk of chronic diseases like cancer and cardiovascular issues.

Tiny plastic particles shed by tires and degrading garbage are polluting the air, potentially causing respiratory and other health problems. ()

A review of some 3,000 studies implicates these particles in a variety of serious health problems. These include male and female infertility, colon cancer and poor lung function. The particles also may contribute to chronic pulmonary inflammation, which can increase the risk of lung cancer.

The Hidden Dangers: Long-Term Health Effects of Microplastics in the Body
Microplastics in the body can cause chronic inflammation, oxidative stress, immune suppression, and increase risks of cancer, reproductive issues, and more.

What are Microplastics

“These microplastics are basically particulate matter air pollution, and we know this type of air pollution is harmful,” said Tracey J. Woodruff, PhD, MPH, a professor of obstetrics, gynecology and reproductive sciences at UCSF.

Woodruff directs the Program on Reproductive Health & the Environment (PRHE) and is the senior author of the study, which appears in the journal Environmental Science & Technology.

Microplastics are less than 5 millimeters – smaller than a grain of rice – and they are ubiquitous in the environment. Each year, companies around the world produce nearly 460 million metric tons of plastic. That is projected to reach 1.1 billion by 2050.

A major source of plastic in the air is driving. Friction wears down tires along with the road surface, sending plastic fragments into the air.

The paper is the first systematic review of microplastics using gold standard methods approved by the National Academy of Sciences.

Most of the studies in the review were based on animals. But the researchers said the conclusions likely also apply to humans since they share many of the same exposures.

The study expands on a report the researchers worked on last year with the California State Policy Evidence Consortium (CalSPEC). The Consortium includes experts across the UC system and provides evidence for policymakers in the California State Legislature.

How Are Microplastics and Cholesterol Raising the Risk?
Experts warn that high cholesterol and microplastics pose significant risks for cardiovascular diseases such as heart attacks and strokes.

“We urge regulatory agencies and policy leaders to consider the growing evidence of health harms from microplastics, including colon and lung cancer,” said Nicholas Chartres, PhD.

Chartres, the study’s first author, led the science and policy team at PRHE and is now at the University of Sydney. “We hope state leaders will take immediate action to prevent further exposures.”
