FTIR spectroscopy measurements and CFD simulations of the pollutants arising from unflued combustion in a room.

Simulates a kitchen for a study of indoor air quality. An extractive FTIR technique was used to measure combustion products from unflued combustion from a gas cooker in a ventilated room. On a comparison of the results with those from conventional instruments, the FTIR technique showed good agreement. The study incorporated the obscuring of the spectrum due to the effects of H2O and carbon dioxide and detection limits. The conditions in the room were investigated using CFD.

The extent of exposure and health effects of household coal burning in urban residential areas in South Africa.

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.
