HHS announces $144 million program to study effect of microplastics on the human body
The Department of Health and Human Services has announced a groundbreaking program called STOMP (Systemic Targeting of MicroPlastics) to study the impact of microplastics on the human body. This $144 million national program will bring together experts in toxicology, data science, and other fields to develop tools for detecting and quantifying microplastics in the human body, research their effects, and create strategies for their removal.
According to HHS Secretary Robert F. Kennedy Jr., research has shown that microplastics are present in human organs, blood, and even the placenta. The STOMP program will prioritize studying the effects of microplastics on vulnerable populations such as pregnant individuals, children, and workers with high exposure rates.
Microplastics are tiny particles from larger plastic items that enter the water supply through various means like littering and storm runoff. Despite being less than five millimeters in size, traditional water filtration methods are unable to completely remove them, as noted by the World Health Organization.
In a related development, the Environmental Protection Agency has added microplastics to its contaminant candidate list for the first time, paving the way for potential future regulations. This list includes substances that are known or anticipated to occur in public water systems, prompting further research and funding to understand their impact on drinking water.
Dr. Celine Gounder, a medical contributor for CBS News and editor-at-large for public health at KFF, emphasized that adding microplastics to the contaminant candidate list is just the beginning of a lengthy process. While widespread evidence suggests potential health risks from microplastics, more research is needed to establish legal limits and determine specific health outcomes associated with exposure.
In addition to microplastics, pharmaceuticals are also set to be added to the contaminant candidate list due to their presence in the water supply from human waste and improper disposal. The EPA has released human health benchmarks for 374 pharmaceuticals to assess risks and take action when drug residues reach concerning levels.
To reduce exposure to microplastics, Gounder recommends avoiding bottled water, refraining from heating food in plastic containers, and improving indoor air quality. While it may be challenging to completely avoid microplastics due to their prevalence, taking these steps can help minimize exposure.
Overall, the STOMP program and the addition of microplastics to the contaminant candidate list mark significant steps in addressing the growing concern of microplastic pollution and its potential impact on human health. Stay tuned for further updates as research and regulations evolve in this critical area of public health.
