A characterization of indoor and outdoor microenvironmental concentrations of pollen and spores in two Houston neighborhoods
Abstract In order to investigate the factors affecting indoor and outdoor microenvironmental concentrations of aeroallergens, and the relationships between them, consecutive 12-hour samples of airborne pollens and spores were collected simultaneously at two fixed ambient air monitoring stations and inside and directly outside of each of 12 houses during the period June–October in Houston. Outdoor concentrations of pollen were spatially less heterogeneous than those of spores, and showed greater seasonal and diurnal variation. Indoor levels of both pollen and spores were uniformly lower than outdoor levels for all 12 air-conditioned homes, with indoor pollen counts on average 30% of outdoor values, and indoor spore counts on average 20% of outdoor values. Indoor levels of both aeroallergens in most homes were not significantly correlated with simultaneous outdoor levels. Variation in exposure to aeroallergens indoors appears largely determined by variations in both infiltration of outdoor air and activities of the household.
