Abstract:
Results from a study of surfactants (SAS) in the sea surface microlayer (SML) and underlying water (ULW) at different locations in the Baltic Sea. The total SAS concentrations were measured using phase-sensitive alternative current voltammetry with hanging mercury drop electrode (HMDE) in unfiltered samples. The concentrations of SAS were expressed as the equivalent concentration of nonanionic surfactants Triton-X-100. The enrichment factors (EF) of SAS were calculated as the ratio of concentration in SML to the corresponding ULW samples.
