Comparison of birch pollen count and Bet v 1 concentration in atmospheric samples and meteorologic parameters in Melbourne (October 16 through November 12, 1996). A, Total Bet v 1 concentrations and corresponding birch pollen counts. B, Bet v 1 concentrations in two particle size fractions (larger and smaller than 7.2 μm). C, Rainfall and average temperature. Bet v 1 data for October 20 and November 3 are not available.

3. Fig. 2
Bet v 1 concentrations in two particle size fractions under various environmental conditions in Melbourne (October 16 through November ). Represented are mean values of Bet v 1 concentrations on days with heavy rain (>1 mm) and first dry days after heavy rain (A, n = 8); Second and following dry days after heavy rain (B, n = 5); days with light rain (<1 mm) and first dry days after light rain (C, n = 8); and second and following dry days after light rain (D, n = 5).
