Efficacy of Recent Emissions Controls on Road Vehicles in Europe and Implications for Public Health

Abstract Road traffic is a major source of urban air pollution responsible for substantial premature mortality. Until recently, attention has focussed primarily on exhaust emissions of particulate matter from traffic as a causal factor. From analysis of air quality measurement data from the UK and F...
