Sources of fine organic aerosol. 7. Hot asphalt roofing tar pot fumes

, : Sources of fine organic aerosol. 7. Hot asphalt roofing tar pot fumes. Environmental Science and Technology 31(10): 2726-2730

The organic compounds present in fine particulate roofing asphalt tar fumes are characterized using GC/MS techniques. Most of the compound mass identified consists of n-alkanes (73%). Polycyclic aromatic hydrocarbons (PAH) and thia-arenes (S-PAH) contribute nearly 8% of the identified compound mass and account for 0.57% of the total mass emissions. When compared to the PAH mass fraction determined in fine particulate exhaust emitted from catalyst-equipped automobiles ([similar] 0.5%) and heavy-duty diesel trucks ([similar] 0.1%), roofing tar pot aerosols show a PAH content similar to that of vehicular exhaust.

The role of flexible endosonography in diagnosis of acute tonsillitis and their complications was investigated in 59 patients. Our results show that flexible endosonography enables the examiner to differentiate acute tonsillitis from peritonsillit...
