| Abstract |
The hazards associated with inhaled fibres are linked with fibre shape, size, composition and durability. In general the asbestos minerals are more durable than most man-made vitreous fibres (MMVF), although some ceramic fibres may be more durable than chrysotile. The most soluble of the MMVF have relatively high alkali (Na and K) and alkali earth (Ca, Mg) contents, and low alumina and boron contents. The least soluble MMVF are the high alumina silicate glasses (the ceramic fibres). The relative durability of different fibre types is governed by the physical and chemical environment which contains the fibres. The effective assessment of fibre durability is an important aspect in fibre safety and requires the development of better and more coordinated experimental design. It may ultimately be possible to design vitreous fibres which have low durabilities in the lung but are adequately durable in the intended environment of use. |
