Description:
Multiple jet impactors are routinely used to measure airborne microbial concentrations in a variety of work and residential environments. nalyses of data collected with these units, however, should account for the possibility of multiple impactions at single sites. ata are usually corrected for multiple impactions using published "positive hole" correction tables. his report describes a new estimator that can be used to correct bioaerosol data collected with multiple jet impactors. he estimator has a simple form and can be easily incorporated into computing environments such as spreadsheets, thus eliminating the need for correction tables. he new approach yields correction estimates that are numerically very close to those obtained with the previously published correction methods. arious properties of the new estimator were examined to evaluate the usefulness of the proposed method.
