Concentrations (pg per g of snow) of metals by atomic fluorescence in the Agassiz Ice Cap in Greenland for the period 1988-1992 are 31 Pb, 1.04 (± 0.17) × 102; Tl, 0.43  0.087; Cd, 3.5 ± 0.87; Zn, 1.74 (± 0.26) × 102; and Al, 6.1 (± 1.7) × 103. The mean annual snowfall was 11.5 g/cm2. Calculate the mean annual flux of each metal in units of ng/cm2. Flux means how much metal falls on each cm2.
