Abstract:
A cross sectional study on the stone dust in the working environment in mines of AC, 504 in Binh Dinh province in dry seasons during 1998 and 1999, has shown that the dust contamination level was high. All indicators were above allowed standards. 9/14 of samples had an airway dust level higher 1-9 time than this of allowed standards. 100% of samples had the total dust level higher 4-37 times than this of allowed standards. The silicon levels in the stone mine of Phu Ly (4-5%) and Hoa An (22-23%). This is cause of silicosis among workers of these facilities.
