Abstract
Airborne dust levels were measured in a plant manufacturing textile and friction asbestos products in summer and in winter. Measurements were performed with four methods: two granulometric (koniometer (K) and thermal precipitator (TP) and two gravimetric (Stapex and SPG-210) ones. the number of fibres (5 µ.m), the number of particles down to the limit of detectability and two aerodynamic particle size fractions, respirable and coarse, in the dust mass, were determined. Granulometric measurements showed a statistically significant correlation between fibres and particles for samples of air from asbestos-textile departments. The relations based on linear regression equations could be expressed roughly as:
- 550 particles/ecru (TP) = 450 particles/ccm (K)
- 7 fibres/ccm (TP) = 5 fibres/ccm (K)
- 5 fibres/ccm (TP) = 200 particles/ccm (TP) and
- 5 fibres/ccm (K) = 280 particles/ccm (K)
The results of gravimetric measurements of airborne asbestos dust need to be further evaluated.
