Microplastics detected in all examined human placentas point to significant environmental contamination and health risks, with future research needed to understand the full implications.
A flurry of recent studies has found that microplastics are present in virtually everything we consume, from bottled water to meat and plant-based food. Now, University of New Mexico Health Sciences researchers have used a new analytical tool to measure the microplastics present in human placentas.
In a study published on February 17 in the journal Toxicological Sciences, a team led by Matthew Campen, PhD, Regents’ Professor in the UNM Department of Pharmaceutical Sciences, reported finding microplastics in all 62 of the placenta samples tested, with concentrations ranging from 6.5 to 790 micrograms per gram of tissue.
