Area 22-h average carbon monoxide (CO), total suspended particulates (TSP),
particles less than 10 mu m in diameter (PM10), and particles less than 2.
5 mu m in diameter (PM2.5) measurements were made in three test homes of hi
ghland rural Guatemala in kitchens, bedrooms, and outdoors on a longitudina
l basis, i.e. before and after introduction of potential exposure-reducing
interventions. Four cookstove conditions were studied sequentially: backgro
und (no stove in use); traditional open woodstove, improved woodstove with
flue (plancha), and bottled-gas (LPG) stove. With nine observations each, k
itchen PM2.5 levels were 56 mu g/m(3) under background conditions, 528 mu g
/m(3) for open fire conditions, 96 mu g/m(3) for plancha conditions, and 57
mu g/ m(3) for gas stove conditions. Corresponding PM10/TSP levels were 17
3/174, 717/836, 210/276, 186/218 mu g/m(3). Corresponding CO levels were 0.
2, 5.9, 1.4, 1.2 ppm. Comparisons with other studies in the area indicate t
hat the reductions in indoor concentrations achieved by improved wood-burni
ng stoves deteriorate with stove age. Mother and child personal CO and PM2.
5 measurements for each stove condition demonstrate the same trend as area
measurements, but with less differentiation.
