Oznake: BC tracer model;secondary organic carbon;black carbon;
In this work, we propose an extension of this method. Using the Aethalometer model (Sandradewi et al., 2008), BC as a tracer for primary emitted aerosols can be successfully divided into two components – BCff related to the usage of fossil fuels and BCbb emitted from biomass burning. Because the OC/ ...

Oznake: aerosol absorption;mineral dust;on-line detection;air quality;
Atmospheric mineral dust influences Earth’s radiative budget, cloud formation, and lifetime; has adverse health effects; and affects air quality through the increase of regulatory PM10 concentrations, making its real-time quantification in the atmosphere of strategic importance. Only few near-r ...

Izvirni znanstveni članek
Oznake: total carbon;aerosol;black carbon;carbonaceous matter;
We present a newly developed total carbon analyzer (TCA08) and a method for online speciation of carbonaceous aerosol with a high time resolution. The total carbon content is determined by flash heating of a sample collected on a quartz-fiber filter with a time base between 20 min and 24 h. The limi ...
