Research shows almost 80% of deaths across four countries were in most polluted regions.
High levels of air pollution may be “one of the most important contributors” to deaths from Covid-19, according to research.
The analysis shows that of the coronavirus deaths across 66 administrative regions in Italy, Spain, France and Germany, 78% of them occurred in just five regions, and these were the most polluted.
The research examined levels of nitrogen dioxide, a pollutant produced mostly by diesel vehicles, and weather conditions.
