Biomass pellets are a source of renewable energy; although, the air pollution and exposure risks posed by the emissions from burning pellets in biomass boilers (BBs) are uncertain. The present study examines the organic species in fine part...
Variability in Observation-based Onroad Emission Constraints from a Near-road Environment [0.03%]
基于观测的路线上排放限制的可变性来自道路周边环境的影响
Heather Simon,Barron H Henderson,R Chris Owen et al.
Heather Simon et al.
This study uses Las Vegas near-road measurements of carbon monoxide (CO) and nitrogen oxides (NOx) to test the consistency of onroad emission constraint methodologies. We derive commonly used CO to NOx ratios (ΔCO:ΔNOx) from cross-road gr...
