| Abstract |
In order to investigate the tendency of polyvinyl alcohol (PVA) fibres to release airborne particles with critical fibrous dimensions (WHO fibres), static and/or personal samples were taken in eight fibre-cement factories at locations where potential exposures to PVA fibres were expected to be the highest. At each factory, a control sample was taken in open air. Sampling, sample preparation and sample analysis by scanning electron microscopy were performed according to standard German procedures. Only very low concentrations of organic WHO fibres, ranging from below the detection limit to 0.006f/mL, were found. These levels are lower than the typical levels of organic fibres commonly found in the normal personal environment (0.009-0.02f/mL), stemming from the release of particles by a person's activities and from clothing and other household textiles. The handling of PVA fibres as well as the machining of PVA and cellulose fibre containing cement products in the fibre-cement factories surveyed have a low potential to release fibres with critical fibrous (WHO) dimensions. |
