초록 | Particulate matter (PM) fromautomobile exhaust has drastic effects on human health. One of the major causesof PM is tire wear and debris from road wear, etc. In particular, tire-wearparticles (TWPs) are further fragmented into nanoparticles, similar to the PMxor black carbon (BC) sources. Carbon black (CB) is used as filler in tires, TWPscan fragment into free-bound nano-CB. This study evaluates the emission factorsof BC from the ternary plots of PMx and BC to estimate theconcentration of nano-CB in TWPs. Based on the emission factors of BC for TWP,approximately 500 monitoring data points were acquired at four different sites.In situ measurement tests, semi-closed sites showed greater BC concentrationsand higher mass concentrations of nano-CB than open sites. TEM analysis reveals grape-like aggregatednanoparticles, which is considered as CB. To compare the effect of the washingout of airborne particulates by rain, further analysis is conducted on a rainyday. |
