Measurements of indoor pollutant emissions were made on
four wood stoves meeting the EPA Phase II emission
requirements in a 37 m2 (400 ft2) test house at NIST.
The stoves were operated in a manner consistent with
typical residential use and in accordance with the
manufacturers' instructions. Three tests were conducted
for each stove, with each test lasting approximately ten
hours. During the tests the following quantitites were
monitored: combined gaseous and particulate phase
concentrations of 13 individual polycyclic aromatic
hydrocarbons (PAHs) averaged over the test period,
including benzo[a]pyrene (B[a]P); total particulate
phase PAH concentrations using a real-time monitor; mass
of particulate matter below ten mm in diameter (PM10)
averaged over the test period; continuous particle
counts in six size ranges; continuous indoor and outdoor
concentrations of carbon monoxide and carbon dioxide;
building air change rates; pressures across the test
house walls and in the stove flue; wind speed and
direction; and indoor and outdoor air temperature and
relative humidity. Based on these measurements,
emission rates of total PAHs (i.e., the sum of eight
individual compounds) ranged from 0.05 to 0.24 ng/s and
total PAH source strengths ranged from 67 to 711 ng/kg
of wood. Emission rates of B[a]P ranged from 0.003 to
0.028 ng/s and B[a]P source strengths ranged from 7 to
90 ng/kg of wood burned.
