Extraction in Dilute Ethanol of Formaldehyde-Fixed Dissecting Specimens

Abstract
To overcome the legally imposed limit on atmospheric concentration of formaldehyde of 1 ppm a method for fixation and storage of material for dissection has been developed. After intraarterial installation of formaldehyde the specimens were extracted in dilute ethanol and stored in the extraction fluid or enclosed in plastic sheets or bags, in a refrigerator. With this method the atmospheric formaldehyde concentration was kept below 0.5 ppm.
