✦ Synopsis

Accumiilation of dissolved organic carbon (DOC) a a s studied in a eutrophic pond and in cultures of Scenedesmus abundans. Samples of pond water and media were treated with a ration exchanger in Xa cycle a i d chromatographed on Sephadex G 25 and G 10. -UV spectra of the peak fractions were recorded. I n the pond about half of the organic carbon is in fractions x i t h an apparent molecular weight (AMW) of 500-1000, while in the algal medium (after cultivation) most of organic carbon has an AMW of about 120. These and spectral data did not suggest that aromatics and compounds with conjugated double bonds %'ere major organic constituents of DOC.

## Abstract The influence of the fishpond on the chemical composition of the stream was mainly demonstrated by a higher concentration of organic matter and total phosphorus. Altogether, 128 species of algae and cyanobacteria were recorded in the stream. The species richness of phytobenthos per site

The depth profiles and seasonal abundance of fatty acids in lipids from the particulate organic matter in the eutrophic Lake Nakanuma, Japan, were closely related to both photosynthetic activity and the difltribution of phytoplankton. The changes in the relative proportions of the fatty acids sugges
