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

Effects of Microplastic Exposure on Human Digestive, Reproductive, and Respiratory Health
Go to source) 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.

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.

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.

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.”
