Size distribution, pulmonary deposition and chemical composition of Hungarian biosoluble glass fibers.

Compared to spherical particles, inhaled fibers may cause enhanced adverse health effects because of their specific shape, thus acting as so-called physical carcinogens. The chemical composition of fibers plays a determining role on the durability and hence may play a potential role in related health effects due to their toxic components. The physical properties, that is, length, diameter, and size distribution, and the chemical composition of fiberglass materials sampled at a Hungarian glass wool factory were investigated.
