Woodsmoke marker levoglucosan: Kinetics in a self-experiment
Tóm tắt
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. Contribution of data on urinary excretion of levoglucosan, to improve biomonitoring and source apportionment of woodsmoke. 1, 3, 5, and 7 hours after5 mg of levoglucosan had been administered orally, urinary excretion was measured by HPLC and mass spectrometry. After oral intake, urine concentrations increased rapidly, reached highest values after3 hours, and after 7 hours approximately 70% of the administered dose was excreted. Urinary levoglucosan may be used for biomonitoring of woodsmoke exposure on the same day.
