Data remarks
- The indicator name refers to a share of area (%), but the form gives the PM2.5 concentration (µg/m³): the definition needs to be reconciled
Methodology
Indicator metadata
- Definition
- Concentration of atmospheric pollution particles per square kilometre, per cent — the share of the area of a territory exposed to polluting atmospheric particles relative to the total area of the territory concerned.
- Calculation method
- The indicator is calculated as the ratio of the area of the territory exposed to atmospheric pollution to the total area of the territory concerned, multiplied by 100.
- Institution responsible for calculation
- Committee for Environmental Protection under the Government of the Republic of Tajikistan
