New research uncovers disturbing presence of microplastics in human placentas
A study conducted by scientists at the University of New Mexico Health Sciences has revealed that microplastics have been found in every human placenta examined. This discovery raises significant concerns about the widespread microplastics contamination and the potential health risks associated with exposure. The authors expressed deep concern about the potential health effects resulting from the escalating volume of microplastics in the environment.
The pervasive nature of microplastics in our daily lives has been increasingly evident through a series of recent studies. These minuscule particles have been detected in various consumables, ranging from bottled water to both animal and plant-based food.
The new study, published in the journal Toxicological Sciences, examined 62 placenta samples. Astonishingly, the researchers found microplastics in every single sample, with concentrations ranging from 6.5 to 790 micrograms per gram of tissue. This accumulation in placental tissue is particularly worrisome, considering the short development period (approximately eight months) of this organ.
The predominant polymer found in the placental tissue was polyethylene, commonly used in the production of plastic bags and bottles, accounting for 54% of the total plastics detected. Polyvinyl chloride (PVC) and nylon each represented approximately 10% of the detected plastics, while the remaining portion consisted of nine other polymers.
Previous techniques relied on visual observation under a microscope, often failing to detect particles that were too small to be seen. With their refined approach, the authors were able to precisely measure microplastic quantities in micrograms or milligrams, depending on the specific plastics present.
This study further raises concerns about the concentration of microplastics found in human tissue, also considering that it is unclear what health effects they might have. Further research is required to fully comprehend the profound implications of these findings.
