Table 1. Diameters, Surface Areas, Pore Volumes, and Pore Diameters of Raw Pollen and SECs.

	raw pollen				SEC
pollen	D_pollen^a (μm)	S_BET (m²/g)	V_p (cm³/g) × 10^–3	D_p (nm)	D_SEC^a (μm)	S_BET (m²/g)	V_p (cm³/g) × 10^–3	D_p (nm)
Pinus	40–43	2.4	1.919	4.9	30–39	1.17	0.554	3.6
F. excelsior	26–27				18–22	10.88	16.00	8.1
Tilia	34–37	1.37	1.048	4.5	34–35	1.05	1.232	6.3

The diameters of raw pollen and SECs were measured based on SEM images. D_pollen, diameter of raw pollen; D_SEC’ diameter of SECs; D_p, pore diameter; S_BET, BET surface area; and V_p, pore volume.
