Abstract:
The ACGIH proposal of 0.1 fibers/liter as TLV for airborne asbestos fibers isn't a properly parameter, because it is applicable in work environments and the Italian legislation has forbidden every work which employs asbestos from 1993 [Law 257/92 and Min.Dec. 6/9/94]. Actually in Italy the application of a TLV is only referred to two analytical results: A) 20 ff/liter by CPOM analysis, B) 2 ff/liter by SEM analysis. We think that a CPOM 4-5 ff/liter is a no trespassing limit and over this concentration alarm may be notified. Waste disposal of asbestos materials must be properly disposed in a restricted area.
