“…60,63,69,72,206 -209,233,234 Quinones, hopanes, and the measured PAHs were in the pg/m 3 range (Ͻ10 to ϳ800 pg/m 3 ) on average. 63,71,77,235 Fossil and Modern Carbon OC in atmospheric aerosols consists of a combination of recently formed carbonaceous material (referred to in the literature as modern, biogenic, or contemporary carbon, although some distinction between these terms can be found; e.g., Hidy et al 236 ) and carbon derived from fossil fuel combustion. Thus, modern carbon has both natural and anthropogenic origins.…”
