“This was striking. These were not high doses of microplastics, but in only a short period of time, we saw these changes,” lead researcher Jaime Ross said.
“To us, this was striking. These were not high doses of microplastics, but in only a short period of time, we saw these changes,” lead researcher Jaime Ross said in a statement.
Because the microplastics were ingested by mouth, it was expected they would be found in the gastrointestinal tract, liver and kidneys — but their expansion to other tissues was shocking. “The brain blood barrier is supposed to be very difficult to permeate. It is a protective mechanism against viruses and bacteria, yet these particles were able to get in there. It was actually deep in the brain tissue.”Getty Images

Microplastics infiltrate all systems of body, cause behavioral changesA new study focused on neurobehavioral effects and inflammatory response to exposure to microplastics, as well as the accumulation of microplastics in tissues, including the brain. The research team has found that the infiltration of microplastics was as widespread in the body as it is in the environment, leading to behavioral changes, especially in older test subjects.
