Recent research has shed light on the potential health risks associated with the increasing presence of micro- and nanoplastics (MnPs) in the environment, revealing a concerning link to major diseases. A study conducted by an international team of researchers has found that human exposure to MnPs may elevate the risk of cancer, diabetes, cardiovascular disease, and chronic lung disease.
Non-communicable diseases (NCDs) are known to be associated with inflammatory conditions within the body’s organs. The study suggests that the absorption of MnPs and their leachates in the digestive and respiratory systems could contribute to the increased risk and severity of NCDs in the future.
Interestingly, the research indicates that concentrations of MnPs in infant fecal matter are notably higher than in adults, potentially due to the prevalent use of plastic in infant food-related activities. Moreover, behaviors common in young children, such as putting objects in their mouths, may also play a role in this heightened exposure.
Published in Cell Reports Medicine, the study underscores the need for a comprehensive global One Health approach to human health and environmental research. By investigating the environmental factors driving human MnP exposure and its association with NCDs, researchers aim to better understand and address the health risks posed by these particles.
Lead author Professor Stefan Krause from the University of Birmingham emphasized the urgency of addressing plastic pollution at its source to mitigate further emissions. The widespread dispersal of MnPs in the environment is expected to pose long-term concerns, necessitating a systematic examination of the environmental factors influencing human MnP exposure and its impact on prevalent NCDs.
The researchers draw parallels between the relationship of MnPs with NCDs and that of other particles, including natural sources like pollen, human-made pollutants such as diesel exhaust, and engineered nanomaterials. These particles are believed to interact with the body in a similar biological manner, emphasizing the need for continued research into their health implications.
