Formaldehyde is determined by the accetylacetone method. Formaldehyde in 4 l of water containing 50 and 200 ppm formalin, in which the test eels were, disappeared comletely within 2 and 3 days, respectively. In control water, formaldehyde in water containing 50 and 200 ppm formalin decreased gradually and disappeared within 4 and 14 days, respectively. The biphasic curve of formaldehyde consentrated was obtained in the muscle,liver and blood of eel when it was exposed to the bath of formalin at 50 and 200 ppm. The levels in tissues decreased gradually and were almost equal to those of the control within 17 - 21 days post bath. The peak levels of formaldehyde in tissues post bath of formalin at 200 ppm showed similar heights to those of formalin at 50 ppm. It could be observed also that the tissues of Japanese eel naturally contain a small amount of formaldehyde.}, pages = {37--42}, title = {Study of quality in fish shellfish as food - I : Concentration of formaldehyde in various tissues of cultured eel by formalin bath}, volume = {11}, year = {1984} }
