• A new study suggests microplastics might directly affect the brain and nervous system.

• Microplastics are tiny plastic fragments smaller than 5 millimeters found throughout the environment, including water supplies and the food chain.

• Researchers exposed zebrafish to microplastics and observed changes in their behavior, including increased anxiety and less social interaction.

• The study also found microplastics accumulating in the brains of the fish.

• It’s still unclear how these findings might translate to humans, but the results raise concerns about potential health risks of microplastic exposure.
