Abstract
Abstract Asbestos fiber deposition upon a filter can be statistically described by a Poisson frequency distribution. Poisson distributions can be developed to model gross, net, and blank fiber depositions. A statistical approach is developed to calculate the analytical limit of detection (ALOD). The ALOD, expressed as fibers/square millimeter, represents the true total sample fiber surface deposition that can be differentiated from a true blank filter at a 95 percent statistical confidence level. Based upon the ALOD concept, an environmental limit of detection (ELOD) is presented that defines the airborne fiber concentrations that are statistically discernible above background at a 95 percent confidence level. The ELOD is expressed in units of fibers/cubic centimeter and depends upon both the volume sampled and the characteristics of the microscope used for analysis. This work demonstrates the importance of collecting and analyzing a sufficient number of field blanks, as they determine the method detectio...
