ABSTRACT
Tributyltin (rBT) concentrations were determined in surfaces water of
the Alexandria coast. Three hot spot sites namely, Western Harbor,
Eastern Harbor and Abu Qir Bay were selected. The water samples were
collected in summer 2000. The values ofTBT in surface seawater samples
ranged from 40 to 579 rtg TBTt’ L. The origin of TBT is in its use as
antifouling agent in marine paints. These TBT concentrations are high and
acute toxic effect on coastal organisms due to TBT may be expected in
those sites.
