A comparison was made between the amount of airborne pollen collected by Burkard airsampler and the allergenic activity of particles trapped on glass fibre filters in an Accu‐Vol high‐volume airsampler. The comparison was made throughout the pollen seasons 1986 to 1989. Both airsamplers were operated 24 h a day. They were placed less than 5 m apart, and estimation of the pollen amount was made on a day‐to‐day basis during the pollen seasons, and on a weekly basis outside the seasons. The occurrence of the 3 clinically most important allergenic types of pollen, birch, grass, and mugwort, was analysed, and close correlations between the 2 sampling techniques were found (r s 0.5–0.8, p< 0.001). The detected range of counted pollens/m 3 was: birch 0–1075, grass 0–156, and mugwort 0–44. By immunochemical analysis we found the corresponding amounts to be 0–80, 0–8, and 0–1 SQ‐U/m 3 respectively. Pollen counts and immunochemical estimation were compared with the symptom score recordings of allergic persons for birch season 1989 and for grass seasons 1986, 1988, and 1989. A close correlation was found for both sampling techniques for the grass seasons in 1986 and 1989 (r s 0.51–0.61, p< 0.001–0.0001), but a less significant correlation was found for the 1988 grass season, and for birch in 1989 (r s 0.24–0.34, p<0.001–0.05).
