  The study faces the challenge of accurately estimating fire-specific PM 2.5 concentrations due to the lack of direct fire smoke observation data. The paper must address the complexity of PM 2.5 sources and the variability of fire influences on air quality. The study needs to account for the uncertainty in estimating health impacts of fire-specific PM 2.5 exposure.
