Abstract: The dissolution, diffusion, and volatilization of a free-phase benzene glob in the presence of air sparging were measured in laboratory-scale air sparging reactors and modeled using a dissolution–diffusion–volatilization ...

Abstract: Experiments on the permeation of several chlorinated and aromatic hydrocarbons through high-density polyethylene (HDPE) geomembranes were conducted using the ASTM F-739 standard test method. The diffusion coefficients were ...

Abstract: Nonequilibrium air-water mass transfer experiments for six volatile organic compounds (VOCs) were conducted using a bench-scale air sparging system. VOCs used were carbon tetrachloride, trichloroethylene, tetrachloroethylene, ...

Abstract: Several farms on the north seashore of Taiwan were contaminated with cadmium and lead since the early 1980s. At the contaminated site, the average soil concentrations of cadmium and lead, analyzed in 1982 and 1996, ranged from
