Particulate matter (PM) is a pollutant released in atmosphere through natural and anthropogenic activities. The PM is one of the responsible for environmental contamination with human health outcomes, especially, respiratory problems; due to the small size they can easily reach the respiratory tract. Therefore, the World Health Organization (WHO) sets global standards related to the limits of PM concentration in the atmosphere. The World Bank Group provides income data based on analyzed variables related to the country economy, preparing annual reports to monitor its development. The aim of this study was to evaluate the continental annual mean concentration of PM2,5 and PM10 in 2013 and 2014, considering the World Health Organization Air Quality Guideline and the relation between the PM concentration and the income for each continent. The results showed that Africa and Asia have higher concentration of PM. In addition, the majority of the studied cities exceeded the WHO recommended limits for PM. Moreover, it was observed that the lower is the income over the continents the higher is the PM concentration, meaning that the population in the poor countries/continents are more exposed to bad air quality.
