Qualitative Analysis of Organic Pollutants in Indoor Air of Newly Decorated Houses / 环境与健康杂志

ABSTRACT

Objective To establish a method of adsorption and thermal desorption-GC-MS and to study the component of organic pollutants in indoor air in newly decorated houses. Methods Used Tenax TA as an adsorbent, the qualitative analysis of the indoor air in two typical newly decorated houses had been done with adsorption-thermal desorption GC-MS method. Results More than sixty organic compounds were detected, besides volatile organic compounds such as acetic acid, glycol, toluene and semivolatile organic compounds such as acenaphthene, anthracene, octadecane, monocyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons, fatty hydrocarbons, oxygen contained hydrocarbons and so on were detected. Conclusion This method can be used for the qualitative analysis of pollutants in indoor air. The organic compounds detected in the air of newly decorated houses are complex of different components.
