14 Indoor air distributions, such as the distributions of air temperature, air velocity, and 15 contaminant concentrations, are very important to occupants’ health and comfort in 16 enclosed spaces. When point data is collected for interpolation to form field 17 distributions, the sampling locations (the locations of the point sensors) have a 18 significant effect on time invested, labor costs ...

Two field studies were conducted for one year using sorbent-impregnated polyurethane foam (SIP) disks for PCB and PBDE air sampling. SIP disks were introduced by Shoeib et al. (2008) as an alternative passive air sampling medium to the polyurethane foam (PUF) disk and have the advantage of a higher holding capacity for organic chemicals. The first study on SIP disks confirmed their application ...

The air in laying hen houses contains high concentrations of airborne bacteria. The numbers of these bacteria can be influenced by the efficiency of the chosen sampling method. In the presented study, AGI-30 Impingers and the Coriolis(®)µ air Sampler were compared in terms of their efficiency in sampling aerobic mesophilic bacteria in a laying hen house. Measurements were conducted in a laying ...

We amplified and sequenced the complete genome of enterovirus D68 (EV-D68) that had been collected from classroom air using a filter-based air sampling method and by swab sampling of environmental surfaces. Relatively high levels of EV-D68 genome equivalents were found per cubic meter of air by quantitative real-time reverse transcription-PCR (RT-PCR).

Biocontamination control is a very significant part of the manufacturing process of sterile drugs. Sterility is frequently monitored by active or passive air sampling measurements, but there are no specific rules as to how this is to be done. This study tested air sampling methods of active impaction and passive sedimentation under standardized conditions. Aspergillus niger (A. niger) and Staph...

Effective evidence-based actions to reduce indoor air pollution must be derived from data obtained using accurate means for assessment of the critical pollutants and identification their sources. This is paramount importance provide robust evidence establishing effective policies or preventive measures. Nevertheless, designing a reliable sampling plan assessing concentration inorganic pollutant...
