☆ Microplastics found in nose tissue at base of brain, study says

CNN —Tiny plastic shards and fibers were found in the nose tissue of human cadavers, according to a small new study. The threads and microplastic pieces were discovered in the olfactory bulb, the part of the nose responsible for detecting odors that sits at the base of the brain. Microplastics are polymer fragments that can range from less than 0.2 inch (5 millimeters) down to 1/25,000th of an inch (1 micrometer). However, an April 2023 study found that microplastics made of polypropylene appeared to exacerbate the advance of breast cancer. The nose is one of many ways through which microplastics can enter the body, experts say.

☆ Human brains contain surprising levels of plastic, study says

CNN —Human brain samples collected at autopsy in early 2024 contained more tiny shards of plastic than samples collected eight years prior, according to a preprint posted online in May. “Compared to autopsy brain samples from 2016, that’s about 50% higher,” Campen said. Nanoplastics are the most worrisome plastics for human health, experts say, because the minuscule pieces can take up residence inside individual cells. In that report, the consortium determined plastics are associated with harms to human health at every single stage of the plastic lifecycle. A March 2024 study found 1 liter of bottled water — the equivalent of two standard-size bottled waters typically purchased by consumers — contained an average of 240,000 plastic particles from seven types of plastics.

☆ Nanoplastics linked to heart attack, stroke and early death, study finds

“Should exposure to microplastics and nanoplastics be considered a cardiovascular risk factor? Nanoplastics have been found in human blood, lung and liver tissues, urine and feces, mother’s milk, and the placenta. The examination found “visible, jagged-edged foreign particles” scattered in the plaque and external debris from the surgery, the study said. Presence of microplastics and nanoplastics, and subsequent inflammation, may act to increase one’s susceptibility to these chronic diseases,” Stapleton said in an email. However, calling the study results “a direct link to cardiovascular disease is a stretch for the findings,” she added.

☆ 4 scientists said they're cutting back on bottled water after measuring the number of microplastics inside

About 10 to 100 times more nanoplastics than microplastics were discovered in bottled water, the study found. AdvertisementScientists said they're cutting back on bottled waterThe inside of an optical box reveals the components that organize the light from laser beams to identify nanoplastics, microscopic plastic pieces. Related storiesAll four co-authors interviewed said they were cutting back on their bottled water use after they conduced the study. Wei Min, the Columbia physical chemist who pioneered the dual laser microscope technology, said he has reduced his bottled water use by half. Previous studies looking for microplastics and some early tests indicate there may be less nanoplastic in tap water than bottled.
