چکیده
Particulate matter with aerodynamic diameter ?2.5 ?m (PM 2.5 ) concentrations vary between countries similar carbon dioxide (CO 2 emissions, which can be partially explained by differences in air pollution control efficacy. However, no indicator of efficacy has yet been developed. We aimed to develop such an indicator, and evaluate its global temporal distribution association country-level health metrics. A novel ambient population-weighted average PM concentration per unit capita CO emission ( P M / C O ), was developed assess country-specific (abbreviated as APCI). estimated mapped the APCI changes during 2000–2016 across 196 countries. Pearson correlation coefficients Generalized Additive Mixed Model (GAMM) were used relationship varied country inverse economic development. showed almost stable trend globally from 2000 2016, low-income groups increased several (China, India, Bangladesh) decreased. The life expectancy at birth (LE), infant-mortality rate (IMR), under-five year age mortality (U5MR) logarithm GDP (LPGDP) ?0.57, 0.65, 0.66, ?0.59 respectively (all values < 0.001). could explain international variation LE, IMR U5MR. associations IMR, U5MR independent climatic factors. consider a good for given relation important population indicators.

"Air pollution and population health" is one of the most important environmental and public health issues. Economic development, urbanization, energy consumption, transportation/motorization, and rapid population growth are major driving forces of air pollution in large cities, especially in megacities. Air pollution levels in developed countries have been decreasing dramatically in recent deca...
