NAAQS Limits (40 µg/m³ annual, 60 µg/m³ 24-hr)
Size: Diameter of 2.5 micrometers or less, roughly 1/30th the average human hair.
Composition: Can be composed of various chemical compounds, including sulfates, nitrates, carbon, metals, and organic compounds.
Sources: Primarily from combustion processes (e.g., power plants, industrial boilers, vehicle exhaust, biomass burning, stubble burning), construction activities, and some natural sources (e.g., dust storms).
Health Impacts: Linked to respiratory diseases (asthma, bronchitis), cardiovascular diseases (heart attacks, strokes), lung cancer, and other systemic health issues.
Environmental Impacts: Contributes to haze, reduced visibility, and can affect ecosystems and climate.
Measurement: Measured in micrograms per cubic meter (µg/m³)a unit of concentration.
Standards: India's National Ambient Air Quality Standards (NAAQS) specify limits for PM2.5 (40 µg/m³ annual mean, 60 µg/m³ 24-hour mean).
