A TSI DustTrak II 8530 monitor (TSI Inc., St. PaulMN, USA) was used to
measure particulate concentrations in the veranda and some of the kitchen
microenvironments. This device provided 1-minute resolution of
respirable dust concentrations. Sampling was performed at 1.7 L/min
using a Dorr-Oliver cyclone attachment (TSI Inc., St. Paul MN, USA).
The DustTrakwas zero calibrated, pre-programmed to run for the appropriate
time, and placed in the location. Data were downloaded via TSI
Trakpro software.
