Background and Objective: Street dust is considered as one of the important sources of particulate matters and heavy metals in the atmosphere. The goal of this study was to assess the heavy metals pollution in street dust of Tehran and evaluate their ecological risk. Materials and Methods: The sampling of street dust was carried out in two areas at the east and west of Tehran. After preparatio...
The issue of air quality conditions and atmospheric pollution in the Arab Region (or Middle East and North African countries) has been addressed through consideration of the energy production and energy consumption pattern. Global, regional and local sources of air pollution in the region have been considered. Emission scenarios of many countries of the region have been outlined. Even though it...
Air pollution exposure causes seven million deaths per year, according to the World Health Organization. Possessing knowledge of air quality and sources of air pollution is crucial for managing air pollution and providing early warning so that a swift counteractive response can be carried out. An optical prototype sensor (AtmOptic) capable of scattering and absorbance measurements has been deve...
Nitrogen dioxide (NO2) is noxious, phototoxic and causes eutrophication. NO2 is one of the major precursors of ground level ozone pollution. Emission rates and emission concentrations of various pollutants from stationary sources of power plant emissions are calculated using Emission Inventory methodologies. Ground level concentrations of Nitrogen oxide (NOx) pollution are predicted by Gaussian...
RESUMO – Quantificação de Poluição do Ar – A atividade industrial é uma das principais causas da poluição do ar urbano. Várias técnicas são utilizadas para monitorar e analisar os agentes poluidores. A técnica de modelamento de receptor é uma delas. A aplicação de programação linear para a quantificação de fontes poluidoras do ar, utilizando o modelamento de receptor, é apresentada neste artigo...
