Jie Yu et al.
Ground water, 51(2), 286-292 (2012-06-22)
Sulfate in groundwater has been previously shown to change the reactivity of Fe(0) in permeable reactive barriers for reducing chlorinated organics. To better understand the effect and mechanism of SO, the degradation of 1,1,1-trichloroethane (TCA) by Fe(0) in unbuffered aqueous

Inhalation toxicology, 23(14), 863-877 (2011-11-17)
The objective of this study was to assess the impact of the exposure duration and intensity on the human kinetic adjustment factor (HKAF). A physiologically based pharmacokinetic model was used to compute target dose metrics (i.e. maximum blood concentration (C(max))
Lelio Zoccolillo et al.
Chemosphere, 76(11), 1525-1532 (2009-06-23)
For the purpose of understanding the transport and deposition mechanisms and the air-water distribution of some volatile chlorinated hydrocarbons (VCHCs), their atmosphere/aquatic environment concentration ratio was evaluated. In addition, for the purpose of differentiating VCHC behaviour in a temperate climate
Ariel Grostern et al.
Environmental microbiology, 12(4), 1053-1060 (2010-01-22)
Chloroform (CF), or trichloromethane, is an ubiquitous environmental pollutant because of its widespread industrial use, historically poor disposal and recalcitrance to biodegradation. Chloroform is a potent inhibitor of metabolism and no known organism uses it as a growth substrate. We

Inhalation toxicology, 22 Suppl 2, 117-125 (2010-09-11)
Workplace air samples from sintering, cokemaking, and hot and cold forming processes in the integrated iron and steel industry were analyzed to determine their volatile organic compound (VOC) concentration. Sixteen VOC species including three paraffins (cyclohexane, n-hexane, methylcyclohexane), five chlorinated
