Title Static electrification of airborne asbestos: A study of its causes, assessment and effects on deposition in the lungs of rats
Bibliographic information Oct. 1981, Vol.42, No.10, p.711-721. Illus. 33 ref.
Abstract The electrostatic charging of asb estos particles, as they become airborne, the magnitude and polarity of the charge, and the effect of the charge on fibre deposition in rat lungs were experimentally determined. Measurements of fibre penetration through an electrostatic elutriator were used to determine that a typical amosite fibre carried a net charge equivalent to 60 electrons. The charge distribution was bimodal. The charge was attributed to contact of the fibres with materials in the dust dispenser during dispersal. The magnitude of the charge could be reduced by introduction of ions from an a.c. corona discharge ioniser. The deposition of asbestos dust into the slowest clearing part of the respiratory tract of rats increased by 40% as a result of the electrostatic charge on the fibres.
