Variations and characteristics of particulate matter, black carbon and volatile organic compounds in primary school classrooms

Indoor black carbon and brown carbon concentrations from cooking and outdoor penetration: insights from the HOMEChem study

“…The concentration measured at the 880 nm wavelength is referred to as the mass equivalent black carbon concentration and hereafter will be referred to as BC. 42 The concentration measured at the nm wavelength is referred to as ultraviolet particulate matter (UVPM); it includes both BC and BrC contributions. 43 The brown carbon concentration was estimated by subtracting the predicted black carbon absorption (linearly extrapolated from σabs at 880 nm assuming AAE value of 1) from the total absorption at 375 nm, which was then converted to a concentration using αabs at 375 nm (24 m 2 g -1 ).…”
