title: Trace metal toxicity to phytoplankton of Kuwait coastal waters.
abstract: Trace metal concentrations in phytoplankton were determined in seven locations (Stations I-VII) of the Kuwait Coast, known for significant industrial and recreational activities. Trace metal concentrations in phytoplankton (20-200 microns size) occurred in the sequence of Zn > Pb > Cu > Ni at Stations I-III and VII, and Zn > Cu > Ni > Pb at Stations IV-VI. Station III showed higher concentrations of all the analyzed metals than at other stations. Toxicity tests to phytoplankton revealed a significant decrease in the rate of oxygen with increasing concentrations of trace metals. Further, such comparisons to station wise observations between the rate of oxygen evolution and trace metal levels revealed the nature of trace metal pollution in each station off the Kuwait coast.
