Abstract
The first study investigates serum IgE and residential endotoxin levels from a cohort of 19 pregnant women living in Trujillo, Peru, and investigates correlations between IgE, endotoxin, demographic, and lifestyle factors in this cohort. Geometric mean for IgE and endotoxin were 246.8 (GSD=4.3) IU/mL and 66.5 EU/mg (GSD=1.7), respectively. Residential endotoxin and serum IgE were not correlated in this cohort. Seventy four percent (14/19) of the subjects in this study had an IgE over 100 IU/mL, a level generally considered elevated. The second study investigates real-time and primarily 24-hr time-integrated levels of PM2.5 (particulate matter d 2.5 microns in diameter) inside and outside (up to 500 ft from the house) of commercial broiler house during tunnel ventilation on a farm in northeast Georgia. None of the 24-hr PMmeasures collected when the houses where in tunnel ventilation 2.5 exceeded the U.S. EPA 24-hr National Ambient Air Quality Standard of 65 ug/m3.
