Air And Noise Pollution are Major Pollutants in Big Cities

Abstract

Road traffic along with extreme urbanization rates are the major sources of urban pollution in big cities of the world. In Europe, for example road traffic Is estimated to generate almost 40% of nitrogen oxide emissions. Traffic is also a significant source of PM10 and PM2,5 particles and lead emissions. The energy consumed by residential, commercial and government buildings generate a large volume of suspended particular matter, rising to almost 60% in the case of PM2,5 particles. They are also a major source of Carbon Monoxide (CO) and black carbon emissions. Most big cities in the world are surrounded by industrial areas occupied by polluting businesses that also contribute to the deterioration of air quality in urban areas. In addition to the gasses generated by fossil fuel burning industry they are responsible for releasing heavy metals, such as nickel and arsenic. Tackling noise and air pollution requires stronger collaboration across all levels of governmental, municipal, scientific and technical organizations. Our task should be the movement towards healthier, quieter and more livable cities.
