| Summary: | The distribution of copper, lead, mercury and
zinc in the Kelang River estuary were studied. Six
stations were selected for sampling. Two of these stations
were in the fresh waterregme while the rest were in the
estuarine zone. The dissolved and total copper, lead
and zinc concentrations in the water column were determined by meatomic absorption spectrophotometer after
chelat on and extraction with solvent. The total man
ganeseandir on concentration in wateraswell as the
extract ablecopper,lead and zinclevelsin the sediment
were studied. The total mercury content in the water
column, sedimentand fishes was determined by cold -vapour atomicab sorptions pectropho to metric method.
The heavy met alcontents in six species of fishes, namely
P1otos usanguil1aris, Ariusthal assinus, Dasyatiszugei,
Gastrophysu slunaris, Setipinna and Johnius carutta
were studied. some physico-chemical parameters of the
water column such as salinity, dissolved oxygen content,
watervelocityand pH were determine at different depths
and stations. |
