www.icrp.orgAerodynamic diameter (d ae) Diameter (lm) of unit density sphere that has same terminal settling velocity in air as the particle of interest. Activity median aerodynamic diameter (AMAD) Fifty percent of the activity in an aerosol is associated with particles of aerody-namic diameter (d ae) greater than the AMAD. Applies to an aerosol where its

Table 1 presents a breakdown of the PM 10 control efficiency ranges by industry for recuperative incinerators (EPA, 1996b). The VOC control efficiency reported for these devices ranged from 0 to 99.9%.
