PM2.5 pollution, population exposed to levels exceeding WHO Interim Target-3 value (% of total)

The proportion of individuals living in areas where annual PM2.5 concentrations surpass the World Health Organization's Interim Target 3 (IT-3) threshold, set at 15 micrograms per cubic meter, serves as a critical indicator of air quality and public health risk. This metric highlights the extent of exposure to fine particulate matter, which poses significant health hazards, including respiratory and cardiovascular diseases. By identifying the percentage of the population affected, policymakers can better understand the scope of air pollution challenges and prioritize interventions. Moreover, with the recommended Air Quality Guideline (AQG) at a stricter 10 micrograms per cubic meter, this indicator underscores the urgent need for enhanced air quality management and the pursuit of cleaner environments to safeguard community health and well-being.
