Abstract:

Field studies of bracken during sporing have indicated very high numbers of spores released per cubic metre of air. The carcinogenic nature of bracken spores poses a health hazard to workers and visitors in areas of sporing strands.

A retrospective study of bracken spores trapped on slides exposed during August and September over the ten year period, 1988–1997, on a rooftop site in Edinburgh, has added an urban dimension to the aerobiology of bracken.

Results have revealed, apart from 1989, consistently low counts. The spore sampler was situated downwind approximately 1.6 km from the nearest sporing stand. A spore calendar, based on the ten years of cumulative data, has been constructed.
