چکیده

W1lliam W Nazaro!f and Glen R. Cass• Environmental Engineering Science California Institute of Technology Pasadena, CA 91125 A general mathematical model is presented for predicting the concentrations of chemically-reactive compounds in indoor air. The model accounts for the effects of ventilation, filtration, heterogeneous removal, direct emission, and photolytic and thermal chemical reactions. The model is applied to the induction of photochemically-reactive pollutants into a museum gallery and the predicted NO, NOx-NO, and 0:5 concentrations are compared to measured data. The model predicts substantial production of several species due to chemical reaction, including HN02, HNOJ, NOJ, and N2Qs. Circumstances in which homogeneous chemistry may assume particular importance are identified and include buildings with glass walls, indoor combustion sources. and direct emission of olefins. Al ~J

Indoor Air Pollution in India – a Major Environmental and Public Health Concern

In many people’s minds air pollution is associated with the contamination of urban air from automobile exhausts and industrial effluents. However, in developing countries, the problem of indoor air pollution far outweighs the ambient air pollution. There are four principal sources of pollutants of indoor air : (i) combustion, (ii) building material, (iii) the ground under the building, and (iv)...

Sorbents for Trapping Organic Pollutants From Air.

A series of siliceous adsorbents with chemically bonded phases (CBPs) of different polarity were tested as sorbents for trapping air pollutants (petroleum ether) using controlled setup. Moreover, special attention was paid to the potential role of metal impurities as strong adsorption sites. Sorbents were characterized by various physico-chemical methods, such as porosimetry, inductively couple...
