Development of strategies to control urban air pollution is a complex and multi-disciplinary process involving a wide range of scientists with different expertise and interests. This paper presents an integrated assessment methodological scheme for the evaluation of air pollution control measures that are put forward in order to reduce sufficiently air pollution levels in urban areas. Forming l...

Background and Objective: Optimum number of air quality monitoring stations in Mashhad is an essential task for management of the urban environment. However, real monitoring and accurate information on the status of air quality require proper spatial distribution of air quality monitoring stations in the city of Mashhad. The aim of the present study was to determine optimum site locations for a...

Exposure to air pollution in city centers is of major concern because of its health-risks to urban dwellers, trafficcorridor users and even to in-transit commuters. The steady growth in traffic is the major source of toxic air pollutants in urban centers these days. Therefore, studying exposure to air pollutants in urban centers is of special interests to environmental health scientists. This s...

Multivariate regression models for real-time coastal air quality forecasting were suggested from 18 to 27 March 2015, with a total of 15 kinds hourly input data (three-hours-earlier PM and gas meteorological parameters Kangnung (Korea), associated two-days-earlier Beijing (China)). Multiple correlation coefficients between the predicted measured PM10, PM2.5, NO2, SO2, CO O3 concentrations 0.957...

Recently the world’s population demographics crossed an important threshold: more people now live in urban than in rural areas (UN 2006). Projections show that the urbanization continues at a significant rate of ~ 1.5% per year, presenting difficult challenges of providing basic needs such as clean air, water and security for urban dwellers while managing available resources efficiently. In thi...
