Cooking emissions show a strong dependence on cooking styles and parameters.
Measurements of the average ultrafine particle (UFP) concentration, PM2.5 and black carbon
concentrations emitted by cooking activities ranged from 1.34 × 104
to 6.04 × 105
particles/cm
3
, 10.0 to 230.9 g/m3
and 0.1 to 0.8 g/m3
, respectively. Lower UFP
concentrations were observed during boiling, while higher levels were emitted during frying.
The highest UFP concentrations were observed when using a gas stove at high temperature
with the kitchen exhaust fan turned off. The observed UFP profiles were similar in the
kitchen and in another room, with a lag of approximately 10 min.
