Introduction: The rapid urbanization coupled with industrial development in Indian cities has led to air pollution that causes adverse effects on the health of human beings. So, it is crucial to track the quality of air in industrial areas of a city to insulate the public from harmful air pollutants.  The present study examined and predicted air quality index levels in industrial areas located ...

asthma is one of the most common diseases in childhood, which has been increased during last decade because of epidemiological pattern changes with climate and industrialization of the communities. there are some controversies on the relationship between air pollution and asthma. tehran, as the capital of iran, is one of the densest populations and is one of the most polluted cities in the worl...

this study assesses the air quality of two urban localities, fahaheel and al-rabia city, to assistlocal authorities to generate information supporting the planning of pollution control strategies to keeppollutants within safe limits in the long run. in terms of diurnal and seasonal variations, almost all measured pollutants exhibited two peaks: one in the morning and another in the afternoon. t...

Evidence is accumulating that indicates air quality problems in residential and commercial buildings are nearly always associated with inadequacies in building design and methods of operation. Thus, the very systems depended on to control the indoor environment can become indirect sources of contamination if diligence is not exercised at each stage of a building's life: a) planning and design, ...

Carbon dioxide detection is a relevant issue in many fields, and this work focuses on the use of a BaTiO(3)-CuO sputtered thin film layer in a gas sensor prototype for air quality measurements. For this, a double side sensor was fabricated, with a Pt heater on one side and the sensing layer over the electrodes on the other side. The uniformity of the temperature on the sensing layer was tested ...

Pollutants in the ambient air result in personal exposure, target tissue exposure and health responses. Ambient air quality measurement using various indicators is important in exposure assessment. Establishment of standard air quality monitoring networks helps in scientific investigation of health effects of air pollution, national and international reporting and to enforce regulations. Partic...

indoor air quality is a general concept that specifies to air quality of buildings and is related to health and relaxation in there. this index contains removal of all contaminants for example microbial, gas types, particles, etc., and suggests remedial approaches toward refreshing the building air and air circulation in these constructions. in this article we study indoor air quality index (ia...

An investigation method to evaluate microbiological air quality has been developed; it involved a compiling building inspections checklist and occupants questionnaires, choosing sites, sampling frequency and analysis procedures. This method has been applied in a representative building with HVAC system and open-space offices. Air samples and microclimate parameters were collected at the same ti...
