Research Finds Increased Risk of Chronic Kidney Disease Linked to Exposure to Fine Particulate Matter (PM2.5)
10 minutes to read
It is widely known that exposure to air pollution is linked to a wide array of health issues, and is most frequently associated with lung and heart issues. However, the damage that air pollution may cause extends far beyond the respiratory and cardiovascular systems.
A longitudinal study published in 2022 has found a link between exposure to fine particulate matter (PM2.5) and the risk of chronic kidney disease.
What is PM2.5? Fine Particulate Matter Definition
Fine particulate matter, or PM2.5, is a common pollutant in both indoor and outdoor air and is one of three classifications of particulate matter.
Particulate matter is a broad class of pollutants defined as any solid or liquid particles small and light enough to remain suspended in the air. PM2.5 particles have a diameter of 2.5 microns (micrometers, or one-millionth of a meter) or less and cannot be seen by the naked eye.
While larger particulate matter, such as PM10 (which has a diameter of 10 microns), can usually be filtered out by the respiratory system before entering the lungs and the bloodstream, PM2.5 is too small for these mechanisms to protect against it effectively. As a result, PM2.5 and its smaller counterpart, PM1 (with a diameter of less than one micron), can enter the body and cause damage to organs through the bloodstream.
