title: Woodsmoke marker levoglucosan: kinetics in a self-experiment.
abstract: OBJECTIVE
  Concerns on climate change are leading to the renaissance of wood burning and particulate exposures. Levoglucosan is used as a marker of woodsmoke in air and urine.
  
  
  OBJECTIVE
  Contribution of data on urinary excretion of levoglucosan, to improve biomonitoring and source apportionment of woodsmoke.
  
  
  METHODS
  1, 3, 5, and 7 hours after 5 mg of levoglucosan had been administered orally, urinary excretion was measured by HPLC and mass spectrometry.
  
  
  RESULTS
  After oral intake, urine concentrations increased rapidly, reached highest values after 3 hours, and after 7 hours approximately 70% of the administered dose was excreted.
  
  
  CONCLUSIONS
  Urinary levoglucosan may be used for biomonitoring of woodsmoke exposure on the same day.
