Workers within the megacity of Los Angeles are exposed to significant amounts airborne particulate matter (PM) during their daily commutes, which often exceed 30–60 minutes each way. Chemical species present in roadway and railway PM, including Benzo[a]pyrene (BaP) hexavalent chromium (Cr6+), substantial cancer non-cancer health risks. In current study, PM samples were collected quantitatively speciated along five major commuter routes, METRO red line (subway) gold (light rail), I-110 I-710...
<ns4:p><ns4:bold>Background:</ns4:bold> Ambient particulate matter (PM) smaller than 2.5 µm in diameter (PM<ns4:sub>2.5</ns4:sub>) undergoes diurnal changes chemical composition due to photochemical oxidation. In this study we examine the relationships between oxidative activity and inflammatory responses associated with these changes. Because secondary PM contains a higher fraction of oxidized species, hypothesized that PM<ns4:sub>2.5</ns4:sub> collected during afternoon hours would induce...
