☆ Microplastics in the brain: New research finds plastics in olfactory bulb

The latest research looked at a part of the brain called the olfactory bulb, which processes information about smell. Connecting the olfactory bulb and the nasal cavity is the olfactory nerve. Some researchers worry the olfactory pathway may also be an entry point for microplastics getting into the brain, beyond the olfactory bulb. Mauad and her team took samples of olfactory bulb tissue from 15 cadavers of people who died between the ages of 33 and 100. The presence of microplastics in the olfactory bulb doesn’t automatically mean there are microplastics elsewhere in the brain, such as regions related to cognition.

☆ 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.

☆ Microplastics discovered in human penises for the first time

CNN —Scientists have found microplastics in human penises for the first time, as concerns over the tiny particles’ proliferation and potential health effects mount. 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). Ramasamy said he wasn’t surprised to find microplastics in the penis, as it is a “very vascular organ,” like the heart. Seven different types of microplastics were detected, with polyethylene terephthalate (PET) and polypropylene (PP) the most prevalent, according to the study. “We need to identify whether microplastics are linked to ED and if there is a level beyond which it causes pathology and what types of microplastics are pathologic,” he said.

☆ Tiny plastic shards found in human testicles, study says

CNN —Human testicles contain microplastics and nanoplastics at levels three times higher than animal testes and human placentas, a new small study found. “They look like little shards, tiny broken bits from very, very old plastics,” said Campen, a regents’ professor of pharmaceutical sciences at the University of New Mexico in Albuquerque. Researchers expected to find more plastic shards in the testicles of older men in the study, but that wasn’t the case, Campen said. “In testes, the levels of plastic was three times as much as we saw in placentas,” Campen said. In studies of pregnant mice, researchers have found plastic chemicals in the brain, heart, liver, kidney and lungs of the developing fetus 24 hours after the pregnant mother ingested or breathed in plastic particles.
