This table provides metadata for the actual indicator available from Moldovan statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available, this table should be consulted for information on national methodology and other Moldovan-specific metadata information.

Indicator 11.6.2: Annual mean levels of fine particulate matter (PM10) |
|---|---|
| Definition and concepts |
Particulate matter with fraction 10 mkm (PM-10) in urban localities represents air pollution mainly in fine duster, and includes a combination of solid and liquid particulates characterised via their reduced dimensions - up to 10 mkm. About 60% of PM10 is composed of particulate of type PM2.5, with diameter under 2.5 microns. According to the World Health Organization, exposure to fine particulate (PM2.5) has the most significant impact on human health as compared to other pollutants. In 2015, the average level of PM2.5 in cities was 15 micrograms per cubic meter and 16.7, in 2016. Atmosphere air quality monitoring: The operation network for atmospheric air quality monitoring includes 18 stationary posts, 17 of which are located in 5 industrialised centres: Chisinau - 6 posts, Balti-2, Tiraspol-3, Bender-4, Ribnita-2, and 1 transborder station in Leova town. The samples are taken at those 17 stations 3 times per day (07:00, 13:00 and 19:00), analysing the basic pollutants (solid matters, sulphur dioxide, carbon monoxide and nitrogen dioxide) and the specific ones (soluble sulphates, nitrogen oxide, aldehyde, phenol and benzo(a)pyrene). The program of observation, collection of samples and chemical analysis is carried out according to the methodology "Руководство по контролю загрязнения атмосферы, РД 52.04. 186-89-Москва 1991” - Guidelines for atmospheric air pollution control. [The air pollution level](http://mediu.gov.md/ro/content/protec%C8%9Bia-aerului-atmosferic) is assesses according to the value of mean concentration as compared to the maximum admissible concentration (CMA), and the quality of air is estimated through air pollution complex index (IPA). |

µg/m3 |
| Method of computation |
Annual mean level of fine particulate matter represents the arithmetic average of fine particulate matter weighted per urban population and expressed in micrograms per cubic meter. Particulate matter with fraction10 mkm is determined via the automated method of measurement, is based on cyclone principle, meant to determine the mass concentration of the fibrinogen fraction sized <10 mkm in atmospheric air. |
| Comparability with global indicator |
The global indicator refers to the mean concentration of PM2.5, weighted per urban population and it is estimated using the satellite data, population estimates, topographic data and measurements in the field. The national indicator refers to the mean concentration of PM10, including PM2.5 and is based on measurements in the field. |
