Assessment of the contributions of volatilization and biodegradation to in situ air sparging performance
Article Abstract:
Aerobic biodegradation and volatilization, when dissolved in contaminant concentrations are <1 mg/L, improve in situ air sparging performance. Bulk water movement, which is produced by water evaporation, with velocity of >2 cm/d toward the air channels can also enhance in situ air sparging performance. Solubility could be the primary chemical factor that can affect the performance of in situ air sparging in remediating very soluble, but slowly degrading fuel oxygenates, such as methyl tert-butyl ether.

A multiple-smoker model for predicting indoor air quality in public lounges
Article Abstract:
The indoor air quality of public smoking lounges at the San Francisco Airport and San Jose International Airport terminals was examined by conducting experiments with monitoring tools. The average carbon monoxide emission per cigarette was 11.9 mg/min. while the average emission for a respirable suspended particle was 1.43 mg/min. These values were consistent with those obtained using a mathematical model for predicting indoor pollutant concentrations.
