Portnoy and Barnes. 2003. This
review article describes aerobiology of pollen and spores as it relates to
human exposure. It reviews a number of studies relating pollen or spore
exposure to clinical symptoms or to mediator release. It also reviews
controlled exposure vs. natural exposure studies, and provides advice for
interpreting pollen counts. The authors
feel that the connection between exposure and symptoms is complex and probably
varies from person to person and allergen to allergen.
