Current pollution meters don’t count the very smallest pollutants – nanoparticles. Recent research suggests these tiny toxic substances could be a major cause of illness and death. By Tim Smedley 15th November 2019 A After years of headlines about air pollution, we’ve been misled on a few things about the world’s biggest environmental health problem.
Aviation-Related Impacts on Ultrafine Particle Number Concentrations Outside and Inside Residences near an Airport
Jet engine exhaust is a significant source of ultrafine particles and aviation-related emissions can adversely impact air quality over large areas surrounding airports. We ...
