Distribution of Manganese, Iron, Copper, Lead and Zinc in Water and Sediment of Kelang Estuary
A study was conducted on the distrubution 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 pgl1,106.5 gil, '10.0 pgl1, 4.1 Ilg/l and 17.9 Ilg11 respe...

| Summary: | A study was conducted on the distrubution 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 pgl1,106.5 gil, '10.0 pgl1, 4.1 Ilg/l and 17.9 Ilg11
respectively. For the dissolved copper, lead and zinc, the values were 4.3 pg/l, 1.6 Ilg/l and 3.9
pgI 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 metalized water and sediment were
comparable to the values reported for other estuarise. The copper and zinc levels were similar to those
found in the world oceans, The results indicate that Kelang estuary is 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 Rivers mouth. |
