The gold mud purchased at Walmart might make your commencement picture fairly or your child reveal a cheerful second. But one blow and it’s perpetually biking as microplastics that can get into our lungs.
Microplastics have infiltrated practically each side of contemporary life, from the private care merchandise we use to the meals we eat. These tiny plastic fragments, usually smaller than a grain of rice, have been linked to potential well being dangers, together with hurt to the digestive, respiratory, and reproductive programs. Some research even counsel they might contribute to severe situations similar to lung and colon most cancers. A current research says that people might have as a lot as one teaspoon of microplastics of their brains!
We are simply beginning to study in regards to the results of microplastics and as they construct up within the physique the consequences could also be irreversible.
According to a newly launched scientific paper, three medical specialists assert that switching from bottled water to filtered faucet water might considerably lower annual microplastic consumption—dropping it by about 90%, from 90,000 to 4,000 particles per yr.
How to scale back publicity to microplastics

Completely eliminating microplastic publicity is unlikely, given their widespread presence within the setting. However, the researchers, publishing in Genomic Press, emphasize that focusing on essentially the most vital sources of consumption is a extra sensible technique.
“The dramatic improve in mind microplastic concentrations over simply eight years, from 2016 to 2024, is especially alarming,” notes Dr. Nicholas Fabiano from the University of Ottawa’s Department of Psychiatry, lead creator of the Commentary. “This rise mirrors the exponential improve we’re seeing in environmental microplastic ranges.”
Bottled water stays one of many largest contributors to microplastic ingestion. Data from the beverage business signifies that bottled water was the most well-liked packaged drink within the US final yr, with Americans consuming 16.2 billion gallons—a 2% improve from 2023. However, plastic particles can shed into bottled water over time, particularly when bottles are squeezed or uncovered to warmth.
“Bottled water alone can expose individuals to just about as many microplastic particles yearly as all ingested and inhaled sources mixed,” says Dr. Brandon Luu, an Internal Medicine Resident on the University of Toronto. “Switching to faucet water might cut back this publicity by virtually 90%, making it one of many easiest methods to chop down on microplastic consumption.”
Other vital sources embody plastic tea baggage, which may launch hundreds of thousands of micro and nano-sized particles per brewing session. He additionally highlights that how we warmth and retailer meals issues. “Heating meals in plastic containers—particularly within the microwave—can launch substantial quantities of microplastics and nanoplastics,” he explains. “Avoiding plastic meals storage and utilizing glass or chrome steel alternate options is a small however significant step in limiting publicity.
“While these adjustments make sense, we nonetheless want analysis to verify whether or not reducing consumption results in decreased accumulation in human tissues.”
If switching to filtered faucet water isn’t an possibility, there are different efficient methods to restrict microplastic publicity.
Beyond bottled water, alcohol and seafood have been recognized as different vital dietary sources of microplastics. Fish swim in a sea of microplastics and once we eat fish, we eat the plastic too. Researchers additionally warn towards heating meals in plastic containers, as this follow can launch hundreds of thousands of microplastic particles per sq. centimeter in simply minutes. Microplastics are lower than 5mm in measurement and a few should not seen to the bare eye. They can fibers from garments, fragments and beads, or items of movie utilized in meals packaging.
Other suggestions for decreasing publicity embody:
- Storing meals in glass or chrome steel as an alternative of plastic
- Limiting consumption of canned and extremely processed meals
- Avoiding microwaving meals in plastic containers
One research discovered that extremely processed meals, similar to hen nuggets, contained 30 instances extra microplastics per gram than unprocessed hen breast. This underscores the function of business meals processing, the place plastics are sometimes utilized in numerous phases of manufacturing.
The world plastic business produces roughly 460 million metric tons of plastic yearly, with projections suggesting this might rise to 1.1 billion metric tons by 2050. We already see analysis that exhibits that recycling applications are a lie within the Western world as most plastics should not recycled and when recycling they emit toxic chemicals.
On a person stage, Americans are estimated to inhale and ingest between 39,000 and 52,000 microplastic particles each year. These particles have been present in human blood, lungs, kidneys, livers, testicles, the mind and even placentas.
Recent analysis means that microplastics can disrupt intestine micro organism, trigger irritation, and hurt intestinal cells. Even extra alarming, a research revealed final month revealed that the human mind might include the equal of a spoonful of plastic fragments.The researchers behind the most recent paper advocate for extra in-depth research on the long-term well being results of microplastic publicity. They additionally name for clear regulatory limits on microplastic consumption.
While minimizing consumption looks as if a logical step, the authors warning that it stays unsure whether or not these reductions will immediately result in decrease plastic accumulation in human tissues. However, given the potential dangers, making easy way of life adjustments—like switching to filtered faucet water—could possibly be a vital step towards decreasing microplastic publicity and defending long-term well being.
