| Zusammenfassung |
| The predictions of two road dust suspension emission models were compared
with the on-site mobile measurements of suspension emission factors. Such a
quantitative comparison has not previously been reported in the reviewed
literature. The models used were the Nordic collaboration model NORTRIP
(NOn-exhaust Road TRaffic Induced Particle emissions) and the
Swedish–Finnish FORE model (Forecasting Of Road dust Emissions). These
models describe particulate matter generated by the wear of road surface due
to traction control methods and processes that control the suspension of
road dust particles into the air. An experimental measurement campaign was
conducted using a mobile laboratory called SNIFFER, along two selected road
segments in central Helsinki in 2007 and 2008. The suspended PM10
concentration was measured behind the left rear tyre and the street
background PM10 concentration in front of the van. Both models
reproduced the measured seasonal variation of suspension emission factors
fairly well during both years at both measurement sites. However, both
models substantially under-predicted the measured emission values. The
article illustrates the challenges in conducting road suspension
measurements in densely trafficked urban conditions, and the numerous
requirements for input data that are needed for accurately applying road
suspension emission models. |
