Title Exposure to cerium oxide in the polishing of handmade glass
Original title Esposizione ad ossido di cerio nella brillantatura del vetro lavorato a mano [in Italian]
Bibliographic information Apr.-June 1999, Vol.12, No.2, p.37-40. 11 ref.
Abstract Cases of pneumoconiosis, pulmonary fibrosis and dyspnoea have been recorded for workers using cerium oxide in manual glass polishing. Approx. 100 glass works in Murano (Venice, Italy) were studied with respect to the exposure of their workers to aerosols containing cerium oxide. Without local air exhaust, the ACGIH TLV/TWA of 10mg/m3 would be exceeded by a wide margin. Local aspiration was shown to reduce dust exposure by a factor of ten. Wet work does not provide sufficient protection, since fine powders (particles measuring 1-2Ám) are particularly hard to wet.
