Approximately seven million people die each year as a consequence of air pollution, with 90 percent of these deaths taking place in low- and middle-income countries, according to new findings. The World Health Organization’s (WHO) latest research shows that although countries are making efforts to mitigate air pollution’s causes, strategies are not keeping pace with population growth.
“We have a long way to go in Brazil,” said Dr. Adalgiza Fornaro, a professor at the University of São Paulo’s atmospheric science department. “In relation to the WHO’s recommendations, all the cities which have established monitoring show that we’re in a pretty bad situation.”
Nine in ten people across the world breathe air containing high levels of pollutants, according to the study. The WHO study separates air pollution into two main categories: ambient (outdoor, such as transport fumes) and household (indoor, such as cooking with polluting fuels).
