Three principal objectives were established for the aeroallergen study, including sampling of Houston air for aeroallergens on a daily schedule for a period of four months beginning in July, 1977, using a documented, reliable, reproducible method; identifying and documenting major aeroallergens which might contribute to allergic responses in humans; and, determining and documenting the accuracy and precision of the qualitative and quantitative determinations required above. The sampling program provided adequate data for the support of the analysis of the health effects data. Daily variations and seasonal trends of aeroallergens were observed which were comparable with expectations for the Houston area. For application to analysis of allergic response, aeroallergens present in the Houston area may be categorized in three major groups: ragweed pollen (Ambrosia), grass pollens (Gramineae), and total mold spores. This conclusion is based on the daily and seasonal variations observed in this study, consultations with area allergists, and review of the available literature.
