PM is a significant concern in epidemiology because of its adverse health effects. Exposure to PM, especially PM2.5, has been linked to a range of health problems, including respiratory and cardiovascular diseases, adverse birth outcomes, and increased mortality rates. PM can penetrate deep into the lungs and enter the bloodstream, leading to systemic inflammation and oxidative stress. Understanding the health impact of PM is crucial for developing public health policies and interventions to reduce exposure and mitigate health risks.
