Microplastics Are Literally Raining from the Sky—Even in Remote Mountains

13. Unknown Health Effects: An Urgent Priority

Although microplastics have been found in various human tissues, their exact health effects remain uncertain.
Scientists warn of possible dangers like inflammation, immune system disruption, and the leaching of toxic chemicals from the plastics themselves.
However, definitive evidence is still lacking, making this an urgent focus for new research worldwide.
International health organizations are now prioritizing studies to fill these critical knowledge gaps.
