Microplastics Found in Every Human Placenta Tested, Study Finds

It's been over three years since scientists first found microplastics swimming in four different human placentas, and as it turns out, that was just the tip of the iceberg.

A few years later, at the start of 2023, researchers announced they had found microscopic particles of plastic waste in no fewer than 17 different placentas. By the end of 2023, a local study in Hawai'i analyzed 30 placentas that were donated between 2006 and 2021 only to find plastic contamination had increased significantly over time.
