Simultaneous air monitoring inside and outside of 12 homes in the Houston area were performed for fine inhalable particulate matter by means of dichotomous samplers. The patterns of house-specific indoor mean concentrations, indoor/outdoor ratios, and probable source of indoor fine aerosol are discussed, along with pertinent information on household characteristics.
The properties of particulate filters and gas adsorption filters have been studied to determine the opportunities available for effectively cleaning the outdoor air supplied to buildings located in urban environments. Class F85 fine filters were studied to determine their collecting efficiency for both atmospheric dust and particulate P AH. Activated carbon adsorption filters were tested to establish their collecting efficiency for toluene, m-xylene and benzene in the concentration range of 1-10 ppm. Long-term tests were also run on a carbon filter in a building in central Stockholm.
The present study was designed to assess health effects in residents of a Bulgarian city polluted by a transboundary chlorine emitter. The study was undertaken on account of the local population's complaints of pervasive specific odour and irritation of respiratory ways and the eyes. The study aimed at assessment of both acute and long-term effects of exposure to air pollution.
Household coal burning is one of the major sources of total suspended particulate matter (TSP) in African urban residential areas in South Africa. The coal stoves used are usually poorly vented or unvented, consequently resulting in high levels of indoor air pollution. The effects of household fuels used in two Townships in the Vaal Triangle (central South Africa) on the health of 8-12 year old children living in these households, were investigated.
The monitoring of air pollution and health levels was carried out in coal burning districts and the districts with central heating in Chengde City. The air pollution levels in winter and summer were compared in coal burning districts and the districts with central heating, indoors and outdoors, in kitchens and bedrooms, before and after the central heating system was used. The health levels of residents who lived in coal burning districts and in the districts with central heating were compared.
In this paper, the conversion of exhaust heat to latent heat is studied as one of the methods for the preservation of the thermal environment in urban areas. A simulation model of exhaust heat management is composed and applied to the soot-and-smoke emitting facilities in the Tokyo Metropolitan Area. The effectiveness is estimated by indices of "coefficient of exhaust heat management" and "conversion ratio of exhaust heat to latent heat".
The constructive uses of vegetation in building engineering services are acoustic quieting, air molecular and particulate filtration, water filtration and chemical polishing, shading from solar gain, cooling and humidification. A water conservation regime should form part of the integrated solution.
