چکیده

A study on the seasonal variation of phytoplankton composition was conducted at upper, middle, and lower parts My Thanh River, which supplies an important source water for aquaculture. Qualitative quantitative samples were collected monthly both high low tide. The results showed that a total 171 (algae) species recorded, belonging to 59 genera 5 phyla. Diatoms most abundant group with highest number, followed by green algae. other phyla possessed number species. more diverse in rainy season tide sampling sites. mean density algae varied from 30,900-43,521 ind.L -1 . diatoms higher middle parts. At same time, euglenoids displayed upper part, showing difference dominant under influence salinity. Salinity found be significantly positively correlated (p<0.01) diatoms, whereas it negatively (p<0.05) blue-green euglenoids. quite diverse, H’ index ranging 2.0-3.3, quality slightly moderately polluted.

Concentration and fate of trace metals in Mekong River delta.

In the Mekong River delta and its associated coastal zone trace elements concentrations (Cd, Cu, Ni and Pb) were measured in the dissolved phase (DP) during dry (March 1997) and wet (October 1997) seasons. As, Co, Cr, Ni, Pb, and Al were also measured in suspended matter (SM) and total and organic carbon, trace elements (Cd, Cr, Cu, Hg, Mn, Ni, Pb, Zn) and macro elements in superficial sediment...
