Athens Naval Hospital, Greece
Histology routines including instrumentation for grossing, embedding and various staining techniques affected air quality. High volumes of formaldehyde fumes , TVOCs and DAB were continuously given off.
In a passive environment (when instruments switched off), the grossing area the VOC concentration was 0.560mg/m³, whereas in the rest of the lab was around 0.120mg/m³.
After one overnight continuous operation of the units, the concentration of formalin in the grossing area dropped to 0.260mg/m3 whereas in the other area of the lab it was 0.032mg/m3.
Concentration continued to decrease over successive days.
Work staff welcomed the significant reduction in odour and the effects of harmful gases, particularly formaldehyde.
