Reusing filtering facepiece respirators (FFRs) has been suggested as a strategy to conserve available supplies for home and healthcare environments during an influenza pandemic. For reuse to be possible, used FFRs must be decontaminated before redonning to reduce the risk of virus transmission; however, there are no approved methods for FFR decontamination. An effective method must reduce the m...

In the event of a large-scale chemical release in the UK decontamination of ambulant casualties would be undertaken by the Fire and Rescue Service (FRS). The aim of this study was to track the movement of volunteer casualties at two mass decontamination field exercises using passive Radio Frequency Identification tags and detection mats that were placed at pre-defined locations. The exercise da...

The decontamination of chemical warfare agents (CWA) using an atmospheric pressure dielectric barrier discharge in air was investigated. Stainless steel samples inoculated with malathion (a surrogate for nerve agent VX) were placed on the cathode, where they were treated by the chemical active species produced in the streamers. An effective decontamination (>99.7 %) was achieved after 10 minute...

Contamination of surfaces by nanomaterials can happen due to accidental spillage and release or gradual accumulation during processing or handling. Considering the increasingly wide use of nanomaterials in industry and research labs and also taking into account the diversity of physical and chemical properties of different nanomaterials (such as solubility, aggregation/agglomeration, and surfac...

The paper is a short review on the soil decontamination applying ex-situ techniques. Some sources and pathways of soil contamination are discussed. It was revealed that available techniques for soil decontamination can be divided in two parts, depending on where the action have place: in-situ or ex-situ. Also, depending on the nature of the process, these techniques can be biological, physical-...

Within the European project "New Safe and Cost Effective Techniques Against Asbestos Risks" different methods for decontamination of asbestos in asbestos containing wastes, abbreviated as ACW from building industry were investigated. A mobile asbestos decontamination unit was developed, aiming at the complete disintegration of asbestos fibres on-site. The process is based on a chemo-thermal tre...

the effect of 10 and 25 kgy ?-irradiation on penicillin g plus procaine and sodium ampicillin has been assessed by different chemical and microbiological analytical methods. according to the chemical results obtained, the antibiotics showed a slight reduction in doses applied but the microbiological assays revealed that the activity of irradiated antibiotics did not reduce. microbiological stud...

by certain fungi belonging to the genus Aspergillus spp and can occur as natural contaminants of poultry food [1]. Aflatoxicosis in poultry causes listlessness, anorexia with lowered growth rate, poor food utilization, decreased weight gain, decreased egg production, increased susceptibility to environmental and microbial stresses, and increased mortality [2]. Also associated with aflatoxicosis...
