Dispersion, Photochemical Conversion and Bioaccumulation of Pollutants near Highway

Abstract

Road traffic is one of the most significant sources of air pollution in urban areas, leading to serious environmental, economic and social problems. The most toxic components of road traffic emissions are oxides of carbon, sulfur and nitrogen, hydrocarbons, aerosol particles, polycyclic aromatic hydrocarbons, heavy metals and dioxins. Several other toxic components are formed in the area of influence of the highway during the daytime due to photochemical processes. This paper provides an analysis of various physical, chemical and biochemical processes that occur near the highway and lead to the transformation of pollutants and their interaction with the environment.
