Bioaerosol measurements were made in 45 Quad Cities, Illinois houses following the 1993 floods of the Mississip pi and Rock Rivers. Least squares log transformed means for fungal concentrations (in cfu m-3) were 1,449 in basements, 1,174 in living ro

In work areas containing multiple sources of the same air pollutant, it is useful for control purposes to be able to separate out the contribution from each individual source. In this study, the chemical mass balance (CMB) receptor model was used to

The printing industry emits large quantities of volatile organic compounds (VOCs) that impact workplace and ambient air quality. Emission factors are a useful way to describe these emissions. Emission factors describe the mass release of a pollutant

The chemical-mass-balance (CMB) receptor model is used to determine and measure specific-source contributions of volatile organic compounds (VOCs) and concentrations of nonmethane organic compounds (NMOCs) in the ambient air. Because the method is ba
