Phytoplankton distribution and productivity in a highly turbid, tropical coastal system (Bach Dang Estuary, Vietnam)

► Estuarine phytoplankton diversity is influenced by organometallic species concentration. ► Impact of inorganic or methylmercury and mono-, di-, and tributyltin varies seasonally. ► Phytoplankton-bacterioplankton coupling varies with salinity, season and diversity.
