Exposure atmospheres for a rodent inhalation toxicology study were generated from the exhaust of a 2000 Cummins ISB 5.9L diesel engine coupled to a dynamometer and operated on a... -
Estimation of Volatile Emissions During the Excavation of Soil or Waste
A model is presented for estimating transient air emissions of volatile chemicals during excavation into a zone of contaminated soil or waste. Using measured in situ parameters,... -
Chloride Retention and Release in a Boreal Forest Soil: Effects of Soil Water...
The common assumption that chloride (Cl-) is conservative in soils and can be used as a groundwater tracer is currently being questioned, and an increasing number of studies... -
Technical Challenges Involved in Implementation of VOC Reactivity-Based Contr...
Controlling VOC emissions on the basis of their individual contribution to ozone formation has been subject to extensive discussion and research in past years, and the concept... -
