Correlated Factors of the Concentration of the Am bient Total Volatile Organic Compounds (TVOCs) at Suvarnabhumi Airport
Charnchai Duangkumnoi, Boonchong Chawasithiwong

The objective of this research was to identify the correlated factors of the concentration of the ambient total volatile organic compounds (TVOCs) at Suvarnabhumi Airport. Measurements of TVOCs, air velocity and dry bul b temperature on the western runway and at the taxi terminal on ground floor were conducted for three consecutive days (March11-13, 2011). Number of flights and taxi services during study were taken from record of the responsible authorities. The results showed that the average ambient TVOCs on the west runway was 0.05 ppm (part per million) and that at the taxi terminal on ground floor was 2.56 ppm. The peaks of the ambient TVOCs of both detection points were in the afternoon. Assumption testing found that only three correlated factors of the ambient TVOCs could be identified. They were number of flights, number of taxi services and detection time.
