Abstract
A stripping method was used to determine the volatile compounds present in the raw water of a reservoir during a heavy bloom of
Synura uvella.
Besides numerous pollution products, a large number of previously unidentified algal excretion products were determined, including alkenes, alcohols, ketones, aldehydes, and nor-carotenoids. The approximate amounts of some important algal excretion products present in the raw water are stated. Their biosynthetic origin and possible function in the ecosystem are discussed. The offensive cod liver oil-like odor which
Synura
imparts to the raw water was traceable to
trans,cis
-deca-2,4-dienal and minor amounts of
trans,cis
-hepta-2,4-dienal.
