This article has been cited by other articles in PMC. Abstract Background Since air can play a central role as a reservoir for microorganisms, in controlled environments such as operating theatres regular microbial monitoring is useful to measure air quality and identify critical situations.
American Industrial Hygiene Association, May;: This study compared the performance of the Isocheck sampler Omega, Inc. The results will determine the correlation between sampling results obtained using the Isocheck sampler in field environments and existing sampling methods for HDI.
|What is Air Sampling?||A secondary objective was to compare the relative performance of the active system with continuous monitors and passive badges; a one-microenvironment i. An additional objective was to demonstrate that the active systems can be worn by children with minimal intrusion i.|

|News section||Active versus Passive Air Sampling - Eddie Salter Feb 11 Read Times Free to read Download One of the most significant developments in air sampling technology in recent years is the evolution of passive samplers. This technology was first introduced to the health and safety profession in by researchers Palmes and Gunnison.|
Seven methods for monitoring HDI oligomer and monomer levels were compared. Fifty-eight sampling sets were collected during spray painting of aircraft and aircraft parts at four Air Force bases. Impinger and cassette samplers were mounted side-by-side on a mannequin located in maximum paint overspray areas.
Additionally, 58 sampling sets of personal breathing zone samples comparing NIOSHIsocheck sampler, and total aerosol mass methods were collected.
Breathing zone air concentrations of HDI monomer ranged from 0. Breathing zone air concentrations of HDI oligomer ranged from 0.
Calculated 8-hour time-weighted average exposure levels ranged from 0. Comparison data among the various sampling techniques has been statistically analyzed and will be available for presentation Keywords Samplers; Sampling-equipment; Sampling-methods; Isocyanates; Spray-painting; Paint-spraying; Paints; Equipment-reliability; Performance-capability; Air-monitoring; Air-samplers; Air-sampling-equipment; Analytical-instruments; Aircraft; Employee-exposure; Workplace-studies; Monomers; Military-personnel; Breathing-zone; Permissible-concentration-limits; Exposure-levels; Exposure-limits; Analytical-methods; Time-weighted-average-exposure CAS No.A long-term pesticide environmental study showed that agreement in the average concentrations improved with increasing length of sampling time between active and passive samplers.

Chapter 2 ENVIRONMENTAL SAMPLING For air pollution studies, an air sample might be taken at fixed intervals of time, say every three hours.
This approach does not require the prior knowledge of pollutant distribution, is easy to implement, and should produce unbiased samples. in comparison to fully random sampling.
Microbiological comparison of hand-drying methods: the potential for contamination of the environment, user, and bystander. In total, this part of the study comprised air-sampling tests (60 tests and 60 controls) with a total testing time of Tisch Environmental Model TEPAS Passive Air S The Region 2 RARE project presentation describes a comparison of active versus passive sampling methods for PCBs in school indoor air. If successful, passive sampling methods may provide a more feasible and cost effective approach for measuring PCBs in school and other types of buildings.
