A study was conducted on the distribution of manganese iron copper lead and zinc in the water and sediment of Kelang estuary in 1981. The mean total levels of manganese iron copper lead and zinc in the estuarine water were 27.1 micro g/1 106.5 micro g/1 10.0 micro g/1 4.1 micro g/1 17.9 micro g/1 respectively. For the dissolved copper lead and zinc the values were 4.3 micro g/1 1.6 micro g/1 and 3.9 micro g/l respectively. In the estuarine sediment the copper lead and zinc contents were 1.92 0.48 and 5.43 ppm wet sediment respectively. The levels of these heavy metals in water and sediment were comparable to the values reported for other estuaries. The copper and zinc levels were similar to those found in the world oceans. The results indicated that Kelang estuary was polluted with lead manganese and iron. However levels of these heavy metals may still be considered safe for aquaculture if the farm is located at least 10 km away from the river mouth

Abstract

A study was conducted on the distribution of manganese iron copper lead and zinc in the water and sediment of Kelang estuary in 1981. The mean total levels of manganese iron copper lead and zinc in the estuarine water were 27.1 micro g/1 106.5 micro g/1 10.0 micro g/1 4.1 micro g/1 17.9 micro g/1 respectively. For the dissolved copper lead and zinc the values were 4.3 micro g/1 1.6 micro g/1 and 3.9 micro g/l respectively. In the estuarine sediment the copper lead and zinc contents were 1.92 0.48 and 5.43 ppm wet sediment respectively. The levels of these heavy metals in water and sediment were comparable to the values reported for other estuaries. The copper and zinc levels were similar to those found in the world oceans. The results indicated that Kelang estuary was polluted with lead manganese and iron. However levels of these heavy metals may still be considered safe for aquaculture if the farm is located at least 10 km away from the river mouth
