Effects of Urban Topography and Traffic Emissions of Ultrafine Particulate Matter, Reactive Nitrogen Species, and Ozone in Greater Los Angeles Area

Abstract

Traffic-related air pollution (TRAP) is a major source of pollutant exposure in urban areas. Particulate species concentrations have drastically increased over the past decade and little has been done to understand them further. This study aims to further research in atmospheric and environmental sciences and influence decisions made regarding urban climate policy by furthering the understanding of UFP size and concentrations. It will lead to a better understanding of dangerous particles and act as a basis for future studies that aim to further understand or mitigate anthropogenic ultrafine particle emissions. This can help policymakers design and implement better, more effective policies that aim to reduce traffic-related air pollution exposure in urban areas.
