Aerobiology of Grass Pollen in the City Atmosphere of Melbourne: Effects of Weather Parameters and Pollen Sources.

摘要: The incidence of grass pollen, estimated by using a Burkard spore trap sited above city building, is correlated with meteorological factors. Pollen was greatest on days high maximum temperatures and reduced humidity or rainfall. Winds from the north, north-west south-east carried highest concentrations pollen. Remote sensing image analysis has been used to identify grasslands over which these winds may have passed before entering city. An pollen yield relative abundance grasses in pastures roadsides north Melbourne implicated ryegrass (Lolium perenne L. rigidum) canary (Phalaris tuberosa) as major sources atmospheric
