Objetivo
TO DEVELOP A METHOD WHICH PERMITS TO REDUCE TIME AND COST OF THE MEASSUREMENT OF THE ASBESTOS FIBRE CONCENTRATION IN THE ATMOSPHERE.
USE IS MADE OF NUCLEPORE FILTERS (PORE DIAMETER 0.2-0.8 UM) COATED ON BOTH SIDES WITH GOLD BY VAPOUR DEPOSITION WHICH, AFTER COATING, ARE TREATED FOR 4-10 MINUTES WITH OXYGEN PLASMA IN A COLD INCINERATOR UNIT; THE ORGANIC COSTITUENTS OF THE SEPARATED DUST ARE "ASHED" WITHOUT LEAVING ANY RESIDUE. THE COATED FILTER REMAINS UNDAMAGED AND CAN BE PLACED UNDER THE SCANNING ELECTRON MICROSCOPE FOR EVALUATION ANY FURTHER PREPARATION.
THE RESEARCH PROGRAMME COMPRISES THREE MAIN STAGES:
1. DEVELOPMENT OF SUITABLE PROCESSES FOR OBTAINING OPTIMUM COATING THICKNESS ON THE MEMBRANE FILTER;
2. ESTABLISHMENT OF WORK SPECIFICATION FOR SAMPLING, TRANSPORT, PREPARATION AND, WHERE NOT ALREADY AVAILABLE, FOR EVALUATION OF THE FILTERS;
3. TESTING OF THE PROCESS AT DIFFERENT INSTITUTES (COORDINATED BY BATELLE-INSTITUT).
