Background & Aims: Health effects of air pollution have increased recently and there are a lot of concerns . Troposphere ozone is a pollutant that mainly enters the body through the respiration. This gas cause respiratory complications (reduced lung capacity, asthma, and nasal congestion), eye burning sensation, and failure of immune defense against infectious diseases. This study was conduc...
in many peoples’ minds, air pollution is associated with the contamination of urban air from automobile exhausts and industrial emissions. growing number of scientific evidence has indicated that in industrialized societies, air within buildings can be more seriously polluted than the outdoor air. in the last couple of decades, with the widespread availability of personal computers, mathematica...
The air quality in Taiwan, at present, is determined by a pollution standard index (PSI) that is applied to areas of possible serious air pollution and Air Quality Total Quantity Control Districts (AQTQCD). Many studies, both in Taiwan and in other countries have examined the characteristics and levels of air pollution with PSI. This study uses air quality data collected from eight automatic ai...
In the early days of abundant resources and minimal development pressures, little attention was paid to growing environmental concerns in Malaysia. The haze episodes in Southeast Asia in 1983, 1984, 1991, 1994, and 1997 imposed threats to the environmental management of Malaysia and increased awareness of the environment. As a consequence, the government established Malaysian Air Quality Guidel...
The city of Tehran undergoes an increasing growth in population as well as industrial activities, both of which increase the concentration of air pollutants. The current research tries to turn a limited and focused system of air contamination measurement and control to an unlimited and extensive one that examines the concentration of each of the contaminants in any area of Tehran. Accordingly, ...
