Indoor VOCs Emission from Cooking Activities in the Philippines

초록

In this study, the VOCs were emitted from different locations: a restaurant and household. Both places used different kinds of fuel, an LPG (liquefied petroleum gas) used in the restaurant and charcoal for the latter. Gas chromatography (HP-6890) with a mass spectrometry is used to analyze the gases emitted. The results showed that charcoal-usage has a higher VOC concentration with a TVOC of 6,688.30 ㎍/m3 than that of using an LPG having 922.76 ㎍/m3. In addition, high concentrations of benzene, toluene and ethylbenzene were present during the 20 minute cooking periods from both restaurant and household. Though high emission concentrations were detected, lack of information has been given to the population regarding this issue. It is important that basic back ground of indoor air quality should be disseminated properly.
