Microplastics have become a widespread environmental concern, with researchers now finding these tiny plastic particles in a surprising new location—medical infusion bags. A recent study published in the journal Environment & Health reveals that microplastics, ranging from 1 to 62 micrometers in size, were detected in filtered solutions used for intravenous (IV) infusions. This discovery raises concerns about the potential health risks associated with the direct delivery of thousands of plastic particles into a person’s bloodstream through IV fluid administration.
In medical settings, IV infusions play a crucial role in delivering essential fluids, electrolytes, nutrients, or medications to patients. These infusions are typically packaged in individual plastic pouches containing a saline solution that closely matches the composition of human blood. While previous research from the 1970s hinted at the presence of solid particles in IV fluid bags, the specific nature of these particles remained largely unexplored.
A team of researchers led by Liwu Zhang and Ventsislav Kolev Valev decided to investigate whether these solid particles in IV fluid bags could be microplastics that pose a potential health risk when introduced into the bloodstream. By analyzing the contents of commercial IV saline solution bags, the researchers found that both brands tested contained microplastic particles made of polypropylene, the same material used in the bags themselves. This suggests that microplastics are shedding from the bags into the infusion solutions.
The study estimated that each 8.4-ounce bag of IV fluid could introduce approximately 7,500 microplastic particles directly into a patient’s bloodstream. For treatments requiring multiple bags of IV fluid, such as dehydration or abdominal surgery, the total number of microplastics delivered could increase significantly. To mitigate the shedding of microplastics, the researchers recommend storing IV infusion bags away from ultraviolet light and heat, as well as implementing micrometer-level filtration systems during infusion.
While the health risks of microplastics exposure through IV infusions have not been fully studied, the researchers emphasize the importance of their findings in informing potential policies and measures to address this emerging issue. By providing a scientific basis for understanding the presence of microplastics in medical settings, this research aims to safeguard human health from potential threats posed by these pervasive plastic particles.

This research sheds light on a previously overlooked source of microplastic exposure and underscores the need for further investigation into the implications for human health.
As we continue to grapple with the pervasive presence of microplastics in our environment, studies like this serve as a crucial reminder of the importance of addressing plastic pollution at every level. By raising awareness and exploring innovative solutions, we can work towards minimizing the impact of microplastics on human health and the environment.
