The Determination and Analysis of Volatile Organic Compounds in Public Buildings

Abstract:

The total content of volatile organic compounds in public places has very important influence on human’s health. In this paper, the author takes indoor air, at a classroom building of a college and a big shopping mall in Qinhuangdao city, as sampling object, and using GC/FIT technology, measures the concentration of total volatile organic compounds (TVOC) and the concentration of benzene contained in indoor environment. Then, through the statistics and analysis of the tested data, taking advantage of the exposure parameter method in the EPA, the risks of environmental to our health are evaluated. The investigation results show that: (1) the contents of TVOC and benzene in the same building in heating day and that in non-heating day are slightly different. In addition, the measured value is higher in heating day; (2) the concentration of TVOC in the store is significantly higher than that in the college classroom building, but the determination values of TVOC in both two public places are lower than the national standard; (3) at some measuring points of the store, the contents of benzene are excessive; (4) through the concentration values of benzene compounds in the two types of establishments, calculates the probability values of causing cancer to the staff ,and they are beyond the value given by United States environmental protection agency (EPA) .
