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...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
the wide availability of data on air pollutant emissions, the knowledge already achieved on theset of chemical and photochemical reactions in the troposphere, the ability to access real time weatherconditions at the local scale that determine the transport and transformation of gases and aerosol, now make it possible to obtain credible and reliable predictions, retrospective analyses and/or fut...

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...
Air pollution and quality monitoring is extremely important in today’s world as it has a direct impact on human health. Air pollution is on the rise due to a number of anthropogenic activities and its monitoring is of vital importance to mitigate certain measures to control it. In this paper we put forward a low-cost and low-power sensor based system for air quality monitoring. This sensor base...
Background:Consequences of air pollution on the health effects, including the formation and aggravation of respiratory ,neurological and cardiovascular disease, caused air quality monitoring and control as something inevitable in most urban & industrial areas issue that should be raised at national level. Industries are among important pollutant factors of the environment that contaminate thei...
Safeguarding and checking of air quality has becoming a most important practice in various modern metropolitan zones now days. The behaviour is unfavourably influenced by types contamination that we get the transportation production power, natural resources utilizes so for emission different poisonous gases making major danger personal life urban communities. getting expanded day day. Our main ...
background: today, air pollution is one of the major problems in large cities including isfahan. methods: the objective of this study was to investigate the variations of ozone (o3), carbon monoxide (co), nitric oxide (no), nitrogen dioxide (no2), nitrogen oxides (nox), sulphur dioxide (so2), and particulate matter (pm10) concentrations in different months at three stations and also to explore ...
Background: The undesirable condition of air quality is one of the most important environmental problems that have challenged many of the world's cities. In this study, considering the importance of particle matter as one of the most important atmospheric pollutants in Ahwaz, the main objective is the air quality assessment of this city in terms of PM2.5 and PM10 in 2016-2017. Methods: The air ...
