15 صفحه اولRelationship between exposure and environmental concentrations in organic solvent workplaces.
The correlation between the exposure concentration (ExpC) of workers and the environmental concentration (EnvC) in their workplaces were examined in 143 printing, painting, gluing, degreasing and other solvent workplaces manned by 535 workers of both sexes. ExpC was measured with carbon felt dosimeters, and EnvC was with grab sampling of air into poly-tetrafluoroethylene bags; both were followe...
متن کاملPersistent organic pollutants in Vietnam: environmental contamination and human exposure.
Global contamination and toxic effects of persistent organic pollutants (POPs) have been an emerging environmental issue and have received considerable attention during the past four decades. Although the extent of contamination by POPs has been dominant in industrialized nations, an increasing number of recent investigations have highlighted the role of the Asia-Pacific region as a potential s...
متن کاملEffects of cleaning and disinfection in reducing the spread of Norovirus contamination via environmental surfaces.
A reverse transcriptase polymerase chain reaction assay was used to study the transfer of Norovirus (NV) from contaminated faecal material via fingers and cloths to other hand-contact surfaces. The results showed that, where fingers come into contact with virus-contaminated material, NV is consistently transferred via the fingers to melamine surfaces and from there to other typical hand-contact...
متن کاملMicrobial contamination of hospital reusable cleaning towels.
BACKGROUND Hospital cleaning practices are critical to the prevention of nosocomial infection transmission. To this end, cloth towels soaked in disinfectants are commonly used to clean and disinfect hospital surfaces. Cloth cleaning towels have been linked to an outbreak of Bacillus cereus and have been shown to reduce the effectiveness of commonly used quaternary ammonium disinfectants. Thus, ...
