The non-public median concentration was 0.04 ppm to the active system and 0.06 ppm for that passive approach (Table one). The region median concentration was 0.04 ppm for the two sampling methods. Through the entire-change, the leading usage of formaldehyde buffered Remedy occurred if the autopsy technician during the histology laboratory and the laboratory coordinator during the pathology laboratory loaded the formaldehyde Resolution in containers of assorted sizes. This was completed Within the laboratory fume hoods (Determine 1a). get more info Identical median concentrations of the personal and location exposures reveal that the main sources of formaldehyde exposures may be with the track record in lieu of from the filling endeavor.
