EFFECT OF HEAVY METAL TO PHYTOPLANKTON MARINE
The combined effect of Cd, Co and Cu to phytoplankton marine in situ experiment was investigated using the full factorial design. The samples were taken before of heavy metal and 1, 3, 5 and 7 days after for to count up of cell number. It was found that various species differ significantly in their response the action heavy metal and their mixture. During exposition reduction of species diversity occurred and population density of most abundant algae decreased. The effect of heavy metal on the decrease of species number and structure of phytoplankton community was also estimated.
