| Abstract |
An analysis procedure developed to give a qualitative and quantitative analysis for organic compounds adsorbed on aerosols collected by Hi-Vol filters was adapted and applied to a similar analysis of aerosols collected by dichotomous filters. Analysis was conducted for five dichotomous samples and two Hi-Vol samples collected in the Houston study. Estimated concentration levels for dichotomous filters of 0.1 to 20 ng/cu m were reported for the 27 organic compounds searched. Compounds detected included carboxylic acid esters, phthalates, n-alkanes and polycyclic aromatic hydrocarbons. The quantities observed in the samples were near the detection limits of the GC/MS-SIM analysis, and blanks of the instrumental system, solvent, procedure and filter elements were necessary to identify artifacts introduced. Filter and solvent blanks contained compounds in the same or higher quantity ranges as did the filter samples, indicating the teflon elements of the dichotomous filters were not cleaned sufficiently prior to use. |
