Abstract

During the summer of 1990 composition and concentrations of free fatty acids (FFA) in the surface film of water were investigated. 23 FFA species were identified. Using cluster analysis in conjunction with ANOVAR correspondence of FFA contents in the surface film with seasonal patterns of pelagic plankton was proved. Three different groups of FFA were revealed, acids of every group had similar seasonal dynamics and presumably were of similar origination. Data obtained gave a chance to suppose that main part of FFA were originated by exudation of living cells of phytoplankton as well as postmortal exudation of bacterioplankton. On the basis of FFA contents in a single sample from the surface film identification of sign of derivatives of phytoplankton biomass was suggested. This express‐assay may be useful for monitoring.
