The Effects of Bis(tri-n-butyltin) Oxide on Three Species of Marine Phytoplankton.

Abstract

The effects of three concentrations of bis(tri-n-butyltin) oxide (TBTO) 1.5, 3.0, and 6.0 ppb) on three species of marine phytoplankton were assessed. Parameters measured were in vivo fluorescence and DCMU induced fluorescence. Fluorescence ratios were calculated from these values. The effects of TBTO exposure varied considerably from species to species. Gymnodinium splendens was the most sensitive, affected by all concentrations of TBTO. Dunaliella sp. demonstrated inhibition of growth at 3.0 and 6.0 TBTO after 3 days. No measurable effects were detected for Phaedactylum tricornutum at any of the TBTO exposures. These data indicate the effect of TBTO on marine phytoplankton may be species specific.
