Chile - 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 Chile was 21.04 as of 2017. As the graph below shows, over the past 27 years this indicator reached a maximum value of 27.25 in 2011 and a minimum value of 20.88 in 2016.

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 pollution, population exposed to levels exceeding WHO Interim Target-1 value (% of total)

PM2.5 pollution, population exposed to levels exceeding WHO Interim Target-1 value (% of total) in Chile was 0.29 as of 2017. Its highest value over the past 27 years was 14.25 in 2011, while its lowest value was 0.29 in 2017.

Definition: Percent of population exposed to ambient concentrations of PM2.5 that exceed the World Health Organization (WHO) Interim Target 1 (IT-1) is defined as the portion of a country’s population living in places where mean annual concentrations of PM2.5 are greater than 35 micrograms per cubic meter. The Air Quality Guideline (AQG) of 10 micrograms per cubic meter is recommended by the WHO as the lower end of the range of concentrations over which adverse health effects due to PM2.5 exposure have been observed.
