Pollutant

  • The Air Quality Pollutant data provides information about a specific pollutant, including its code, display name, full name, concentration, and additional information.

  • Pollutant concentration is measured using standardized units like parts per billion (ppb) or micrograms per cubic meter (µg/m^3) and includes a numerical value representing the concentration level.

  • Additional information about the pollutant includes details about its main emission sources and potential health effects.

  • The pollutant's code name can be used to identify it and find more information about it in the reported pollutants documentation.

  • Pollutant concentration is measured and reported using standard units.
