The development of phytoplankton in the sewage-polluted seawater taken in Oostende port (Belgium) when diluted with synthetic seawater at different levels as derived from the result of the pigment analysis

This study investigates the development of phytoplankton in brackish seawater at different levels of sewage pollution. The sewage polluted seawater taken in Oostende port Belgium (on 18 March 2002) was diluted with synthesis seawater at the same salinity (14SPU) in the four tanks (T1, T2, T3 and T4). The levels of the sewage-polluted seawater in the tanks were 100, 60, 30 and 10% corresponding. The tanks were kept at room temperature (20°C), under cool white light frames (200Wm -2 ) put on 12hrd -1 . The phytoplankton composition as derived from the pigment analysis shows that in the sewage-po... Mehr ...
