nowadays, air pollution is one of the main challenges worldwide. there have been significant improvements in air quality dispersion modelling. aermod is one of these models which is based upon the gaussian model. however, aermod has some limitations in terms of data input and output. therefore improving this model as well as developing new models adopted to our country is required to be address...

Quality evaluation of urban environment is an integral part of efficient urban environment planning and management. The development of fuzzy set theory (FST) and the introduction of FST to the urban study field attempts to incorporate the gradual variation and avoid loss of information. Urban environmental quality assessment pertain to interpretation and forecast of the urban environmental qual...

swelling urban populations and increasing number of industry and especially automobiles in and around cities have resulted in adverse effect on human health. one of the most important things regarding air pollution in these days is that the number of motor vehicles has increased, and the resulting problems of new types of air pollution on large scale need to be emphasized in large cities.the gr...

background: national institute of environmental health sciences (niehs) scientists shows that long-term exposure to air pollutants increases the risk of respiratory diseases such as allergies, asthma, chronic obstructive pulmonary disease, and lung cancer. children and the elderly are particularly vulnerable to the health effects of ozone, fine particles, and other airborne toxicants. air pollu...
