: Nosocomial infections may result from intensive care unit pulse oximeters. The descriptive study examined oximeter sensor microbiological contamination and the efficacy of manual disinfection with alcohol sodium hypochlorite in five hospital units. Sixty-eight reusable sensors were swabbed, cultured, evaluated after decontamination. In private public hospitals, 12 (35.2%) 13 (37.2%) oximeters...
Following a CBRN incident, first responders use decontamination procedures to reduce the risk of exposure. The effect of decontamination on forensic trace material has, however, not been fully examined. This study sought to evaluate the effect of five different physical or chemical decontamination materials on the recovery of latent fingerprints. Fingerprints were deposited on glass slides, dec...
This paper describes a trial of chlorine dioxide in dental unit waterlines to produce potable quality water. Four treatment protocols using 50 ppm activated chlorine dioxide solution were tested. Each caused a short-term (<48 h) decline in total viable counts but did not provide potable quality water. Intermittent use of chloride dioxide is thus not suitable for long-term decontamination of den...
This study introduces spatially targeted decontamination using a synergistic combination of dielectric barrier discharge (DBD) flow actuation and ozone generation. Here, we relate the spatial distribution local microbial decontaminations in an enclosure to that concentrations caused by DBD generation two reactors with contrasting actuation, Fan Comb reactors, run at equal power 1 ± 0.03 W for 3...
OBJECTIVE To compare the simple, swab 'Kudoh method' for culturing Myobacterium tuberculosis from sputum samples, to the standard Petroff digestion-decontamination procedure. The Kudoh method, which requires no centrifugation and takes only 4-5 min per sample, was also evaluated for its performance in a rural setting. METHODS Two hospital laboratories in Caracas, Venezuela processed 314 sputu...
isotopic and nuclear techniques play an important role in food and agriculture, health and industry. in the agricultural sciences and food technology sectors, recent research has elucidated the new potential application of radiation for microbial decontamination, food preservation, improve the nutritional quality of foods and effectively utilise its potential as human food or animal feed. the...
The efficacy of currently available decontamination strategies for the treatment of indoor furnishings contaminated with bioterrorism agents is poorly understood. Efficacy testing of decontamination products in a controlled environment is needed to ensure that effective methods are used to decontaminate domestic and workplace settings. An experimental room supplied with materials used in office...

In this work, we have attempted to review the current knowledge on the impact of elevated CO2, O3, and UV on soils. Elevated CO2 increases labile and stabile soil C pool as well as efficiency of organic pollutants rhizoremediation and phytoextraction of heavy metals. Conversely, both elevated O3 and UV radiation decrease inputs of assimilates to the rhizosphere being accompanied by inhibitory e...
BACKGROUND Dental unit waterlines (DUWLs) are ideal environment for development of microbial biofilms. Microbial contamination of water in DUWLs is thought to be the result of biofilm formation as it could serves as a haven for pathogens. The aim of this study was to assess microbial quality of water in dental unit waterlines of dental units located at the dental school of Isfahan University of...
