The World Health Organization (WHO) and the University of Bath have creative an interactive map demonstrating findings from their newly developed method for calculating air pollution which reveals that 92 percent of the world’s population live in places with dangerously high levels of pollution. The method uses satellite and ground-level data and airflow models to calculate the concentration of ultra-fine particulate matter, such as sulphate and nitrates, which can increase people’s risk of respiratory and cardiovascular diseases. They found that the vast majority of people live in areas where air pollution levels exceed the WHO-recommended limit of 10 micrograms per cubic meter.”
