There is an increasing evidence of air related sickness among infants and housewives in urbanIndia due to the use of liquefied petroleum gas. An attempt has been made in this study, tomonitor kitchens of 13 houses in the city of Jaipur for possible residential indoor air pollution(IAP), i.e. carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2) and respirablesuspended particulate matter generated during cooking. The role of the exhaust fan as aninexpensive means to dissipate these gases of combustion has also been studied. Theconcentrations of CO and SO2 were found to be negligible. Levels of RSPM far exceeded theacceptable WHO guideline value and NO2 levels exceeded the 1 h average WHO guideline in5% of the cases. It was also observed that the use of an exhaust fan during cooking dissipatedalmost 30-60% of the pollution generated, but its location vis--vis the gas stove was found tohave a significant effect on the efficiency.
