conclusions results of this study showed that the screen3 software is one of the popular models for estimating the distribution of air pollutants. nitrogen dioxide emissions are highly regulated in most industrialized regions. decreased emissions from fuel combustion, the use of scrubbers and filters that absorb pollution can be very useful for reduction and control of nitrogen dioxide emission...
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 study provides a statistical trend analysis of different air pollutants using Mann-Kendall and Sen’s slope estimator approach on past pollutants statistics from air quality index station of Varanasi, India. Further, using autoregressive integrated moving average model, future values of air pollutant levels are predicted. Carbon monoxide, nitrogen dioxide, sulphur dioxide, particu...
Background and aims: The emission of sulfur dioxide in air has hazardous effects on human health and environment. In this research the use of surfactants with sodium bicarbonate and limestone for the removal of sulfur dioxide was studied. Methods: A packed scrubber was used and the effect of absorbents (limestone or sodium bicarbonate), the kind and concentration of surfactants were assessed...
Background and aims: With the increasing air pollution to volatile organic compounds, in critical demand of a new environmentally, friendly technologies to remove these contaminants from the air stream is of interest to everyone. Photocatalytic processes, including processes, are considered, radiation may be in the future as a new and promising technology used for the removal ...
Carbon dioxide capture is a key issue in climate change mitigation. For decades the removal of carbon dioxide has been an essential step in many industrial processing operations such as the synthesis of ammonia, natural gas purification, and oil refining. In this study, a rotating packed bed has been designed for absorption of carbon dioxide from an air stream. The rotating packed bed is a comp...
Present study deals with the relationship between ambient air sulphurdioxide and sulphate content in leaf of selected tropical plant species, Ficus religiosa. The study reveals a positive correlation between ambient air sulphur dioxide and sulphate in the leaves. Two way ANOVA finds the obtained values to be highly significant (p < 0.001). Amount of sulphate in leaves shows positive correlation...
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 ...
