A NEW APPROACH TO THE INVESTIGATION OF ALLERGENIC RESPIRABLE PARTICLES USING A MODIFIED ANDERSEN IMPACTOR

Pollen allergens have been shown to occur in fine particles much small er than pollen grains. As such allergenic particles have a nigh probab ility of entering the lower human airways, it is important to further investigate their origin and their biological and immunological proper ties. Accordingly, we have modified the particle collection surface of an Andersen Impactor using adhesive coated microscope slides to enabl e identification by high resolution microscopic analysis and immunodet ection of allergenic particulates.
