Possibility of siliceous pollution in goldsmith workshops

: The AA. carried out a research in order to determine the entity and the localization of siliceous dust pollution in goldsmith-field in the industrial area near by Valenza Po, Northern Italy. The research put attention just on the microfusion process and it was carried out among factories that attend to this process continuously. In fact the "scagliola" is used only during microfusion. It is a sort of mixture containing a high quantity of quartz and cristobalite used for the moulding. Dangerous dusts are caused by the mentioned "scagliola" during stripping and mixing. The use of right technical precautionary measures can surely eliminate the risk.
