“…The health impact of air pollution by nitrogen incurs social costs that are already in the hundreds of billions of USD. This is because nitrogen compounds represent a significant part of urban pollution with fine particles (PM 2.5 ) whose health cost in terms of premature deaths is estimated at USD 1.8 trillion in OECD countries and USD 3.0 trillion in the BRIICS countries (Brazil, Russia, India, Indonesia, China and South Africa) (Roy and Braathen, 2017).
