Indoor air pollution has recently become a public concern in Taiwan. People recognize that indoor air quality (IAQ) may be more important than outdoor air quality because they spend over 80% of their time indoors. IAQ could affect health and comfort of building occupants. The objectives of this study are (1) to characterize the indoor concentrations of selected air pollutants at two hospitals i...

Air pollution issues in South Africa were only brought to public attention in the late 1980’s when concern was expressed over the high emissions from industries on the Highveld (east of Johannesburg). Air pollution issues have since been raised in other parts of the country such as Durban and Cape Town. Although the research and monitoring of air pollution has been largely fragmented and uncoor...

There is a mechanism of the Coulomb screening of charging of a localized electronic state located inside a conductor, which was first discussed by G. Mahan, P. Nozieres and C. De Dominicis, and by K. D. Schotte and U. Schotte [1]. They demonstrated that the rate of a one-electron jump 1/Γ, (h̄ = 1) undergoes exponential renormalization due to both the reconstruction of the Fermi seas and the exc...

BACKGROUND Air pollution has become a major global public health problem. A number of studies have confirmed the association between air pollutants and emergency room (ER) visits for respiratory diseases in developed countries and some Asian countries, but little evidence has been seen in Western China. This study aims to concentrate on this region. METHODS A time-series analysis was used to ...

Air pollution is an higher threat for not only the environmental condition of any country, also a biggest factor for global warming. In this decade , the nation planning commissions of every country shift their focust to get solutions for air pollution and trying to save the environment conditions of the country. We hope this is the first article which tries to provide some solution which could...

The proliferation of urbanization and industrialization cause’s immense fluctuations in air quality due to pollution.The air pollution can be minimized effectively by defensive measures through the efficient air pollution/quality prediction techniques. The existing air quality prediction models are tedious and time consuming.Soft Computing paradigm hasemerged out to be more flexible, less assum...

Quantifying human exposure to air pollutants is a challenging task. Ambient concentrations of air pollutants at potentially harmful levels are ubiquitous in urban areas and subject to high spatial and temporal variability. At the same time, every individual has unique activity-patterns. Exposure results from multifaceted relationships and interactions between environmental and human systems, ad...

This research paper is an attempt towards analyzing real time air pollution data collected by PAQS sensor devices from some key locations in Bangalore. Air pollution in most of the metropolitan cities in India is turning out to be a major threat to our environment and hazardous to our health. Many infections and diseases related to lungs and throat are caused by the polluted air we breathe. The...

Epidemiologic studies of the respiratory health effects of air pollution are intrinsically difficult because exposure is common, expected effects at concentrations found in developed countries are weak, random misclassification of exposure is common, and the respiratory health indicators have multiple etiologies. Exposures to air pollutants also are multidimensional, generally consisting of a m...
