Scientists believe microscopic particles, called nanoplastics, come from all the plastic people use and throw away. When plastic breaks down over time, it winds up in the food supply, the water we drink, and even the air we breathe.

Recent research has detected nanoplastics—tiny plastic particles—in human tissues, including the brain and kidneys. Scientists have found that people living near nanoplastic-polluted environments face higher risks of heart disease, stroke, and diabetes. Studies have also shown a greater presence of plastics in the brains of individuals with dementia compared to those without.

Ongoing long-term clinical studies are tracking the health effects of plastic exposure from pregnancy through adolescence. Early findings suggest links between nanoplastics and hormonal, fertility, and cardiovascular problems. Experts emphasize that reducing plastic use is a crucial step to mitigate these health risks.

The impact of nanoplastics on long-term health

Tonight, there's growing concern about invisible threats in our environment. A recent study links people living near nanoplastic-polluted oceans to higher risk of heart disease, stroke, and even diabetes. So, what are nanoplastics? As CBS' medical contributor, Dr. Celine Gounder reports, they're found everywhere, including inside of us. So, these bright spots, that's the plastics. Right. The bright spots on Matt Kampen's screen are tiny pieces of plastic found in tissue from a human kidney. Kampen studies the health effects of environmental pollutants, and his lab at the University of New Mexico has, for the first time, found plastics in human brain tissue. So you've estimated that the amount of plastic in the brain could be roughly the size of a plastic spoon. Is that a lot? That is a lot. The fact that it's getting worse over time is really the issue. Scientists believe these microscopic particles, called nanoplastics, come from all the plastic people use and throw away. When plastic breaks down over time, it winds up in the food supply, the water we drink, even the air we breathe. And we're using more plastics than ever. Kampen's lab has found more plastic in the brains of people with dementia than those without. Sounding great. Now research on these nanoplastics is moving out of the lab and into long-term clinical studies. We have more evidence now for the effects of plastic on children's chronic disease than we do of food dyes. We should be acting as fiercely on plastics in the food supply as we are on food dyes. New York University's Dr. Leonardo Tresande is tracking plastics' impact on over 64,000 kids. From pregnancy to adolescence, including eight-year-old Jack Glaser. Jack's mom, Tammy Freed-Glaser. The amount of information that they're collecting is remarkable. They did cognitive studies on Jack, you know, height and weight and sonograms and beyond. So far, Tresande's research has linked plastics to health problems, including hormonal issues with fertility and cardiovascular disease. Literally, the particle is a problem because it's a foreign body in a tissue. It might thrash the lining of the coronary artery, contributing to clogging. These are toxic drug delivery systems. The details are still emerging, but experts agree less plastic is the way forward. Dr. Celine Gounder, CBS News, Albuquerque.
