Wherever possible, estimates of PM 2.5
have been computed using standardized categories and
methods in order to enhance cross-national comparability. This approach may result in some cases
in differences between the estimates presented here and the official national statistics prepared and
endorsed by individual WHO Member States.
These differences between WHO and national statistics may be larger for occur in countries with small
cities and settlements which may not be fully represented by the resolution of the WHO model. This
may be compounded for isolated regions where air pollution is primarily from local sources and is
experienced at very local levels.
