Lower middle income - Particle pollution

PM2.5 air pollution, mean annual exposure (micrograms per cubic meter)

The value for PM2.5 air pollution, mean annual exposure (micrograms per cubic meter) in Lower middle income was 62.62 as of 2017. As the graph below shows, over the past 27 years this indicator reached a maximum value of 65.98 in 2011 and a minimum value of 59.04 in 1990.

Definition: Population-weighted exposure to ambient PM2.5 pollution is defined as the average level of exposure of a nation's population to concentrations of suspended particles measuring less than 2.5 microns in aerodynamic diameter, which are capable of penetrating deep into the respiratory tract and causing severe health damage. Exposure is calculated by weighting mean annual concentrations of PM2.5 by population in both urban and rural areas.

PM2.5 air pollution, population exposed to levels exceeding WHO guideline value (% of total)

PM2.5 air pollution, population exposed to levels exceeding WHO guideline value (% of total) in Lower middle income was 99.14 as of 2017. Its highest value over the past 27 years was 99.96 in 2012, while its lowest value was 99.14 in 2017.

Definition: Percent of population exposed to ambient concentrations of PM2.5 that exceed the WHO guideline value is defined as the portion of a country’s population living in places where mean annual concentrations of PM2.5 are greater than 10 micrograms per cubic meter, the guideline value recommended by the World Health Organization as the lower end of the range of concentrations over which adverse health effects due to PM2.5 exposure have been observed.
