1. introduction one of the most important conditions to have dusty weather beside of unstable weather is existence or non-existence of humidity. unstable weather having enough humidity will produce rain and thunder storm, else if the result will be dust storm. number of particles of dusty storm is depended to wind speed, sec of soil and its dimension. furthermore, vegetation type has importance...
BACKGROUND Particulate air pollution episodes have been associated with increased daily death. However, there is little direct evidence that diminished particulate air pollution concentrations would lead to reductions in death rates. We assessed the effect of air pollution controls--ie, the ban on coal sales--on particulate air pollution and death rates in Dublin. METHODS Concentrations of ai...
BACKGROUND We conducted a meta-analysis to evaluate the association between traffic-related air pollution and lung cancer in order to provide evidence for control of traffic-related air pollution. METHODS Several databases were searched for relevant studies up to December 2013. The quality of articles obtained was evaluated by the Strengthening the Reporting of Observational Studies in Epidem...
OBJECTIVES To determine whether previous symptoms or recognized risk factors of cardiovascular ill health, are associated with an increased likelihood of adverse health effects related to particulate air pollution. METHODS Cardiovascular event rates were studied relative to urban concentrations of particulate air pollution and baseline risk factors. The Edinburgh artery study consisted of a c...
background: air pollution and concerns about health impacts have been raised in metropolitan cities like tehran. trend and prediction of air pollutants can show the effectiveness of strategies for the management and control of air pollution. artificial neural network (ann) technique is widely used as a reliable method for modeling of air pollutants in urban areas. therefore, the aim of current ...
Air pollution is a major global environmental problem, with various adverse effects on health and the environment. This introductory article provides an overview of related global and regional legal instruments. The article evaluates the legal landscape in terms of its coverage, geographic scope and effectiveness, and concludes that the legal measures currently in place fall far short of provid...
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...
