Microplastics, tiny plastic particles less than 5 millimeters long, are everywhere and have been found in humans from the depths of the ocean to the heights of Mount Everest. These micro- and nanoplastics come primarily from larger plastics that degrade over time and can be produced through various human activities, such as construction, agriculture, and manufacturing.
Exposure to microplastics occurs through air, water, food, and even our clothes. Humans breathe in these particles and ingest them, with higher concentrations found in highly processed foods and meat. Research suggests that plants absorb microplastics from the soil, which can then be ingested by animals.
Studies have shown that microplastics may harm reproduction, lung function, gut health, and increase the risk of cancer. However, it is essential to note that extrapolating effects on humans from animal studies can be challenging due to varying exposure levels.
To minimize your exposure, experts recommend simple changes such as:
* Not drinking from plastic water bottles
* Avoiding heating food in plastic containers
* Eating more fresh fruits and vegetables
* Vacuuming regularly and using an air purifier with a HEPA filter
* Washing clothes made of synthetic fibers before wearing them
However, it’s crucial to acknowledge that individual actions may have limited impact due to the widespread presence of plastics in our environment. Governments need to regulate and reduce nonessential plastics to stop accumulation.
As experts emphasize, there is growing public awareness about microplastic pollution. While 20 years ago changes seemed daunting, the shift now marks a turning point towards reducing plastic waste.
