Evaluation of Indoor Emissions from Household Products Using Headspace Technique
Abstract
Information about the chemical components emitted from the household products employed in many othercountries seems to be still relatively scant and insufficient. The emissions composition for 59 consumerproducts were evaluated using a headspace analysis. The chemical composition and concentrations of totalvoalatile organic compounds (VOCs) broadly varied along with products. No volatile pollutants were detectedfor only one product in the household product category of laundry detergents. Except for this product, 1 to17 organic compounds were detected in the headspace gas phase of each product. The category of oilpaints exhibited an upper range for both the number of chemicals detected and the concentrations of totalVOC. The chemical composition of certain household products determined in the current study was differentfrom that for other studies from other countries. Four to 37 compounds were detected in the headspace gasphase of each product class. Several compounds were identified in more than one product class. Althoughseveral results indicated the dependence of the headspace temperature or period on the proportions ofconstituents in headspace gas phase, the effect of the headspace conditions on headspace concentrationsvaried along with the type of household product or analyte. It is suggested that a proper headspaceconditions should be considered based on the volatility of components and matrix of each household productas well as the analytical sensitivity.
