Abstract: 

Rationale Various types of adhesive media are used for preparing tapes or slides for capturing airborne particles for spore trap samplers. Each adhesive has different physical properties and may not be appropriate for all locations or all seasons. This study compared the capture efficiency of two adhesives commonly used for preparing Burkard slides and drums. Methods Two Burkard spore traps were positioned approximately four meters apart on the roof of a five-story building at Ochsner Clinic Foundation in New Orleans, LA. The tapes for one sampler were prepared using Dow Corning High Vacuum Grease (HVG) and tapes for the second sampler were prepared using Lubriseal (LUB). Slides from 1 July to 7 Aug 2007 were analyzed to determine the spore capture during high summer temperatures. Spore concentrations were log transformed prior to statistical analysis. Results Samples prepared using HVG trapped significantly higher levels of total spores. Mean concentrations of total spores for the period were 7232 spores/m3 using HVG and 6232 spores/m3 using LUB (t = 2.42; p
