Measurements of sediment toxicity of autotrophic and heterotrophic picoplankton by epifluorescence microscopy

Sediment toxicity from Toronto (Ontario) and Toledo (Ohio) harbours to autotrophic and heterotrophic picoplankton was evaluated simultaneously using epifluorescent microscopy. The approach is a simple, fast and effective combination of autofluorescence and fluorescence probes - 1-anilino-8-naphthale...

Description
Summary:Sediment toxicity from Toronto (Ontario) and Toledo (Ohio) harbours to autotrophic and heterotrophic picoplankton was evaluated simultaneously using epifluorescent microscopy. The approach is a simple, fast and effective combination of autofluorescence and fluorescence probes - 1-anilino-8-naphthalene sulfonic acid. The procedure is ideally suited for use with sediment slurries since it can differentiate fluorescent biotic material against a background of abiotic sediment particles and detritus. (DBO)
