2010/8/12
The goal of this research is to quantify diesel- and gasoline-powered motor vehicle emissions within the Mexico City Metropolitan Area (MCMA) using on-road measurements captured by a mobile laboratory...
Study on the Seasonal Variation and Source Apportionment of PM10 in Harbin, China
Atmospheric particles Seasonal variation Enrichment factor Source apportionmen
2016/3/29
The atmospheric respirable particulate matter (PM10) from four typical districts of Harbin was collected in four seasons.
By analyzing the samples, we got the spatial distribution and seasonal variat...
Source apportionment of elevated wintertime PAHs by compound-specific radiocarbon analysis
