"Presence of Microplastics in Human Placentas Raises Concerns for Mammalian Health"
A study led by University of New Mexico Health Sciences researchers found microplastics in all 62 human placenta samples tested, with concentrations ranging from 6.5 to 790 micrograms per gram of tissue. The most prevalent polymer found was polyethylene, used in plastic bags and bottles. The researchers used a new analytical method to quantify the microplastics, expressing concern over the potential health effects of the increasing volume of microplastics in the environment. They plan further research to understand the impact of microplastics on human health, as plastic production continues to rise globally.
