Aldehydes are found only in the hypolimnion, not in the upper aerobic water layers. The highest aldehyde content in three series of vertical samples is 0.11 mg./l. in terms of formaldehyde equivalents. It was shown by laboratory experiments that formaldehyde is rapidly decomposed in aerobic lake water, but very slowly in anaerobic lake water. In sea waters, aldehydes are not found in the surface water layer, and no systematic variation is noticed in the verticall distribution.Read More
