Particulate Matter

Meaning

Particulate Matter (PM) is a complex, heterogeneous mixture of microscopic solid particles and liquid droplets suspended in the air, categorized by size, such as PM2.5 and PM10, based on their aerodynamic diameter. This pervasive environmental pollutant is clinically significant because its inhalation is directly linked to systemic inflammation, oxidative stress, and the potential disruption of sensitive endocrine and metabolic systems. It represents a major environmental challenge to human hormonal health.
