Aerodynamic diameter measurement of cellulose acetate fibers from cigarette filters: what is the potential for human exposure?

Abstract

Aerodynamic diameter is a major determinant of particle and fiber deposition and toxicity in the respiratory tract. To characterize cellulose acetate fibers released from the filter end of cigarettes puffed under conditions approximating smoking, we designed multistage impactors to determine the aerodynamic diameters of large fibers with circumscribed… (More)
