原始语种摘要: Levoglucosan, a highly specific tracer of particulate matter from biomassburning, has been used to study the influence of residential wood burning,agricultural waste burning and Boreal forest fire emissions on the Arcticatmosphere black carbon (BC) concentration. A one-year time series fromMarch 2008 to March 2009 of levoglucosan has been established at the Zeppelinobservatory in the European Arctic. Elevated concentrations of levoglucosanin winter (mean: 1.02 ng m−3) compared to summer (mean:0.13 ng m−3) were observed, resembling the seasonal variation seen for e.g.sulfate and BC. The mean concentration in the winter period was 2–3orders of magnitude lower than typical values reported for Europeanurban areas in winter, and 1–2 orders of magnitude lower thanEuropean...
