  1. Pollen and fungal spores indoor and outdoor of mobile homes.

    Article - En anglais

    Background 

    Allergenic diseases triggered by aeroallergens extract a health cost in quality of life and in economic impact.

    People generally spend 90% to 95% of their time indoors, so understanding the environmental factors that affect the presence of aeroallergens indoors are important in understanding health impact and potential intervention methods.

    Objective 

    Describe the relationship of indoor airborne pollen and fungal spores in occupied mobile homes with outdoor concentrations and other environmental factors within geographically diverse areas of Texas.

    Methods 

    Airborne pollen and fungal spores were collected during the daytime with RotoRod samplers indoor and outdoor of mobile homes in Houston and El Paso, Texas.

    Samples were counted simultaneously with a dual eyepiece microscope and identified morphologically and through staining techniques.

    Results 

    Geometric mean concentrations (counts/m3) indoors and outdoors for pollen, respectively, were Houston 7.1 and 196.4 ; and El Paso 17.5 and 71.5. Geometric mean concentrations (counts/m3) indoors and outdoors for spore, respectively, were Houston 98.5 and 196.4 ; and El Paso 36.9 and 71.5. Indoor to outdoor ratios (I/O) for pollen and fungal spores were found to be higher on average than has been previously reported.

    Modeling of predictive factors in Houston demonstrate that 62% and 41% of indoor levels of pollen and fungal spores, respectively, can be explained by their corresponding outdoor levels. (...)
