Trace metal (Co, Cu, Fe, Pb and Zn) concentrations were determined in Karachi coastal waters (Bath Island, Keamari and Korangi) using atomic absorption spectrometric technique. These metals have been quantitatively separated from sea water matrices as metal-APDC complex using MIBK as an extractant. The extract was directly aspirated into atomic absorption spectrometer and a reproducible signal was obtained. The results showed prominent variations in metal concentration with distance and also from one sampling area to another. Seasonal variations were also monitored.
