AIMS To evaluate the decontamination of Bacillus anthracis, Bacillus subtilis, and Geobacillus stearothermophilus spores on indoor surface materials using hydrogen peroxide gas. METHODS AND RESULTS Bacillus anthracis, B. subtilis, and G. stearothermophilus spores were dried on seven types of indoor surfaces and exposed to > or =1000 ppm hydrogen peroxide(More)
Tri-n-butyl phosphate (TBP, CAS No. 126-73-8), an industrial chemical, was administered in the diet at concentrations of 0, 200, 700 and 3000 ppm to groups of 50 male and 50 female Sprague-Dawley rats for 2 years. Body weights and food consumption were measured weekly for the first 13 weeks and monthly thereafter. Hematology was performed at 12, 18 and 24(More)
vessels does not significantly change the system protocols or introduce any complications. Direct steam injection provides several benefits to the overall process and is equal in efficacy to the currently used method.

Tri-n-butyl phosphate (TBP), an industrial chemical, was administered in the diet at concentrations of 0, 150, 1000 or 3500 ppm to groups of 50 male and 50 female CD-1 mice for 18 months. Survival, clinical signs and hematology parameters were unaffected by treatment at any concentration. Initial weight losses and significant decreases in body weight gain(More)
A two-generation bioassay on sodium saccharin (NaS), involving 2500 second-generation male rats, was designed to determine the dose response for urinary bladder tumours in male rats and to evaluate other changes possibly related to the occurrence of the tumours. Six treatment groups (125-700 rats/group) were fed dietary levels of NaS ranging from 1.0 to(More)
AIMS To evaluate the decontamination of Bacillus anthracis, Bacillus subtilis, and Geobacillus stearothermophilus spores on indoor surface materials using formaldehyde gas. METHODS AND RESULTS B. anthracis, B. subtilis, and G. stearothermophilus spores were dried on seven types of indoor surfaces and exposed to approx. 1100 ppm formaldehyde gas for 10 h.(More)
