Sanitizing radish seeds by simultaneous treatments with gaseous chlorine dioxide, high relative humidity, and mild heat
"Greater amounts of gaseous ClO2 were measured at 23% RH than at 100% RH; however, the lethal activity of gaseous ClO2 against naturally occurring mesophilic aerobic bacteria was significantly enhanced at 100% RH." "Gaseous ClO2 was produced in higher amounts at 55 °C than at 25 °C, but decreased more rapidly over time. The lethal activity of gaseous ClO2 against MAB on radish seeds was greater at 55 °C than at 25 °C."

A study of the properties of chlorine dioxide gas as a fumigant
******Purogene brand. "ClO2 gas is easily generated by mixing 3.35% sodium chlorite solution (Purogene) and 85% phosphoric acid at a 10:1 volume ratio without using an expensive machine. In a test room (87 m3), experiments were carried out using various amounts of sodium chlorite solution (0.25 ml/m3 to 20.0 ml/m3). The gas concentration increased in a sodium chlorite volume-dependent manner and reached peak values of from 0.8 ppm to 40.8 ppm at 2 h–3 h" "without humidification, the efficacy of ClO2 gas was apparently attenuated" "No differences in gas concentrations were observed between 0.1 and 2.5 m above the floor" "Delicate electronic devices (computer, camera, etc.) operated normally, even after being subjected to more than 20 times of fumigation."

2000-G chlorine dioxide slow-release gas sachets used. "Generally, embryos are negatively affected by early continuous exposure to ClO2. The adverse effect decreases at later stages of development of embryo. Treatment of hatching eggs in the Treatment of hatching eggs in the hatcher (18-21 days) proven to be safe. Short (12 hour) treatment of eggs in the setter, every time a new batch of eggs is moved in, seems to be also safe. Treatment with the levels of ClO2 safe for eggs seems to be effective in control of Aspergillus contamination."

Development of an online biosensor for in situ monitoring of chlorine dioxide gas disinfection efficacy
A prototype bioluminescence-based biosensor was designed and constructed to evaluate the antimicrobial efficacy of chlorine dioxide (ClO{sub 2}) gas under various treatment conditions. The biosensor consisted of a bioluminescent bioreporter (Pseudomonas fluorescens 5RL), an optical transducer (photomultiplier tube), and a light-tight chamber housing, the bioreporter and the transducer. The bioluminescent recombinant P. fluorescens 5RL in the biosensor allowed for online monitoring of bioluminescence during ClO{sub 2} gas disinfection. Experiments were performed to evaluate the effects of th...

The treatment process appeared to have no effect or increase the concentrations of endotoxin and (133)--D-glucan, which have been associated with respiratory symptoms in some individuals." "Endotoxin concentrations before and after ClO2 treatment were 10.32 and 18.59 endotoxin units per cubicmeter (EU/m3), respectively. Paired tests comparing endotoxin concentrations before and after treatment showed no significant difference. " "House tented decontamination: Greater than 650 ppm in air for 12.5 hours" "Both the total microscopic count and the PCR count obtained for air samples decreased significantly. This could be caused by direct reduction of spores in the air or reduction of spores on surfaces that would serve as the source for the airborne spores. However, no decrease was observed in the semiquantitative analysis of amount of spores and hyphae in the stickytape samples collected from surfaces."
