    Abstract:
    We have monitored Juniper pollen which caused winter allergy symptoms by Burkard sampler in Galveston, Texas. We identified and counted Juniper pollen grains by PAAA protocol which was a comprehensive guideline for the operation of Hirst-Type suction bioaerosol sampler, (original of Burkard sampler) in the USA. In Galveston we were able to detect the Mountain Cedar (Juniperus ashei) pollen from December to of January, and Eastern Red Cedar (Juniperus virginiana) which has cross reactivity to MC from almost middle of January to February. There is no MC vegetation in Galveston. We found the pollen grains were transported from west at Edward Plateau in West Texas where it was thickly wooded. Then, we tried to monitor Japanese Cedar (JC) pollen grains in Fukuoka, Japan according with the same method. We found the significant positive correlation between the pollen counts using one single longitudinal traverse counting technique in the PAAA protocol and the JC pollen counting on the whole of Melinex tape per 24 hours (R2=0.9212, p=0.0001), and the gravitational method that is Durham sampler's pollen counting in 2002 (R2=0.489, p=0.0001), and in 2003 (R2=0.948, p=0.0001) respectively. We suggested that we can use the PAAA protocol for airborne pollen investigation in Japan by Burkard sampler.
