You have collected three samples for lead fume using 0.8 um pore size MCE filters in closed face 37-mm cassettes with a sampling pump that you assumed was operating at a flow rate of 3.0 L/min. Each sample was collected for 7 hours and on this basis the laboratory reported the following results: Sample No. 1-0.080 mg/m² Sample No. 2-0.065 mg/m² Sample No. 3 -0.030 mg/m² However, after double checking your rotameter calibration curve, you find that the pump was sampling at a flow rate of 2.5 L/min. What are the corrected results for the samples? a) Sample No. 1 = b) Sample No. 2 = c) Sample No. 3 = You have collected three samples for lead fume using 0.8 um pore size MCE filters in closed face 37-mm cassettes with a sampling pump that you assumed was operating at a flow rate of 3.0 L/min.
