Abstract
Road fugitive dust(RFD) is a main source of atmosphere particulate matter in city.Road dust-fall(DF) was monitored and PM10 emission strength was calculated with AP-42 emission factor model in Huhhot roads,the feasibility of DF monitor RFD was studied.DF of 30 roads were monitored and silt loading,traffic volume and mean weight of the vehicle fleet were sampled,analyzed and recorded,and PM10 emission strength were calculated of the monitored roads,relationship of DF and PM10 emission strength was studied.Results showed that DF values of the roads were out circle road major arterial minor arterial collector local,with the values as 76.3,36.1,31.7,25.8 and 19.0t/(km2·30d) respectively,and the background value was 9.4t/(km2·30d).PM10 emission strength of the out circle road,major arterial,minor arterial,collector and local were 178,169,130,100 and 11 kg/(km·d) respectively.DF positively correlated with PM10 emission strength,and the latter can be calculated by formula Q=2.6×(DFr-DFb),it is feasibility for DF to evaluate RFD emission and study characteristics of RFD.
