While evidence suggests associations between maternal exposure to air pollution and adverse birth outcomes, pregnant women’s exposure to household air pollution in developing countries is understudied. Personal exposures of pregnant women (n = 100) in Trujillo, Peru to air pollutants and their indoor concentrations were measured. The effects of stove-use related characteristics and ambient air pollution on exposure were determined using mixed-effects models.
Significant differences in 48-hr kitchen concentrations of particulate matter (PM2.5), carbon monoxide (CO), and nitrogen dioxide (NO2) concentrations were observed across fuel-types (p < 0.05). Geometric mean PM2.5 concentrations were 112 μg/m 3 (CLs: 52, 242 μg/m3) and 42 μg/m3 (21, 82 μg/m3) in homes were wood and gas were used respectively. PM2.5 exposure was at levels which recent exposure-response analyses suggest may not result in substantial reduction in health risks even in homes where cleaner burning gas stoves were used.
