this study investigated single-step extraction of heavy metals from contaminated sedimentscollected in the port of cádiz. experimental tests of washing with an aqueous solution of a chelating agent wereperformed at selected solid/liquid (s/l) ratios. two chelating agents were chosen: 0.3 m edta(ph 3.8 and 8)and sodium citrate (1 m). the objective of the tests was to investigate extractive decon...

We evaluated four decontamination methods and one nondecontamination procedure in combination with four egg-based media for the primary isolation of Mycobacterium ulcerans from tissue specimens. With mycobacterial recovery and contamination rates of 75.6 and 2.4%, respectively, the combination of the oxalic acid decontamination method with Lowenstein-Jensen medium supplemented with glycerol yie...

OBJECTIVE This study evaluated the effect of root canal disinfectants on the elimination of bacteria from the root canals, as well as their effect on glass-fiber posts bond strength. MATERIAL AND METHODS Fifty-three endodontically treated root canals had post spaces of 11 mm in length prepared and contaminated with E. faecalis. For CFU/ml analysis, eight teeth were contaminated for 1 h or 30 ...

OBJECTIVE To determine the comparative efficacy of selective decontamination of the digestive tract in critically ill surgical and medical patients, and in selected subgroups of surgical patients with pancreatitis, major burn injury, and those undergoing major elective surgery and transplantation. DATA SOURCES The MEDLINE database was searched from January 1966 to December 1996 using the term...

Studies have been conducted to determine the efficacy of various decontamination technologies against virulent B. anthracis and surrogate spores within small, bench-scale chambers. This study assessed an approach for evaluating room-scale (~2,700 ft3) decontamination efficacy of vaporous hydrogen peroxide fumigation against B. anthracis Ames and B. subtilis spores deposited onto porous and non-...

Many irrigation ponds in Fukushima Prefecture were decontaminated due to the contamination of radiocesium released from Daiichi Nuclear Power Plant. To evaluate impact decontamination on 137Cs dynamics an urban pond Koriyama City, Prefecture, Japan, temporal changes concentrations bottom sediments and water investigated before after bottom-sediment removal. Post-decontamination, inventories dec...

Meta-analyses of randomised controlled trials of selective digestive decontamination have clinical outcome measures, mainly pneumonia and mortality. This meta-analysis has a microbiological endpoint and explores the impact of selective digestive decontamination on Gram-negative and Gram-positive carriage and severe infections. We searched electronic databases, Cochrane Register of Controlled Tr...

The aim of this study was to develop a test system to evaluate the effectiveness of procedures for decontamination of respirators contaminated with viral droplets. MS2 coliphage was used as a surrogate for pathogenic viruses. A viral droplet test system was constructed, and the size distribution of viral droplets loaded directly onto respirators was characterized using an aerodynamic particle s...
