APPLICABILITY: The working range is 0.5 to 10 mg/m 3
for a 200-L air sample. This method is not applicable for the
determination of "cyclohexane-solubles" [3]. This analysis is simple but the method is nonspecific. Information on any o ther
particulate materials present should be assessed. The method may be extended to higher air concentrations (e.g., nuisanc e dust
levels) by collecting a smaller sample volume [4]
