Airborne microplastic pollution could have serious effects on human health, according to a meta-analysis carried out by the University of California. This study suggests that these tiny particles, in addition to damaging the reproductive, digestive, and respiratory systems, could be linked to colon and lung cancer.
The meta-analysis examined over 3,000 previous studies, selecting 31 relevant studies, of which 28 were conducted on animals and 3 on humans. Although many of the results were obtained in animals, researchers believe that the conclusions can be extrapolated to humans due to similarities in environmental exposures.
According to the meta-analysis, these particles have the potential to cause chronic lung inflammation, which increases the risk of developing lung cancer. They are also associated with fertility problems in men and women, as well as colon cancer.
Microplastics are plastic particles smaller than 5 millimeters, smaller than a grain of rice. They are generated from the decomposition of plastic waste and tire wear on roads. These particles are released into the environment, becoming a form of air pollution that can contribute to respiratory, digestive, and reproductive diseases.

Microplastics: a global issue
Given that microplastics are present in almost all ecosystems, including the human body, researchers warn that their impact could extend to other body systems. This represents a key area for future research aimed at better understanding the risks and developing strategies to reduce exposure.
“Microplastics in the air are essentially particulate air pollution, and we know that this type of pollution is harmful to health,” explained Tracey Woodruff, co-author of the study and researcher at the University of California, San Francisco.

Call to Action
The research team emphasizes the need for regulatory agencies and policymakers to take action on this emerging issue. “It is crucial to consider the growing evidence of the harm that microplastics can cause to health, including the risks of colon and lung cancer,” noted Nicolas Chartres, lead author of the study and member of the University of Sydney.
The main sources of airborne microplastics, such as tire wear and plastic waste decomposition, require urgent attention to mitigate their impact on public health and the environment.

What Are the Consequences of Microplastics for Health?
Microplastics are plastic particles less than 5 millimeters that can be harmful to human health and the environment:
Human Health
Microplastics can cause health problems if ingested or inhaled:
Ingestion: It can lead to gastrointestinal problems, inflammation, and other health issues.
Inhalation: It can cause respiratory problems and other health issues.
Environment
Microplastics can:
Be ingested by wildlife and fish, causing physical harm and affecting their ability to feed.
Contribute to the accumulation of plastic pollution in the environment, which can disrupt ecosystems and alter the balance of natural processes.
Contaminate the environment, especially the sea, due to poorly managed plastic waste.
Microplastics can originate from:
The breakdown of larger products such as bottles, bags, and synthetic textiles.
The action of water, sun, wind, and microorganisms on discarded plastic in oceans and seas.
Products like facial scrubs or toothpastes.
To reduce the amount of microplastics, some countries have banned the manufacture of personal care products containing microbeads.
