Water samples were taken from the recreational lakes using polypropylene sample containers which had been acid soaked. The water was filtered over 0.22 pm Millipore filters, and the suspended sediment collected for metal analyses. Heavy metal analyses were also done in the meat portion of the most common fish found in the recreational lakes, i.e. Tilapia nilotica. The fish were caught without baits to avoid contact contaminating their internal organs.

The presence of 76 )ig Pb in the fish meat of Tilapia nilotica from the Jaya pond is also good evidence of the critical level of Pb in the Kuala Lumpur urban air. High levels of Pb and Zn in aquatic organisms have been reported in many other places. Mussels from the Derwent estuary (Tasmania) were found to accumulate several hundred pg g of Pb, and over a thousand jig of Zn [ 26 ]. However,...

Ichthyotoxic Activity of Alcohol Extract The fish used in this experiment are Puntius gonionotus Smith, Poecilia reticulata Peters, Cyprinus carpio Linn, and Tilapia nilotica Linn. The ichthyotoxic activity of the alcoholic extract was performed by following the method of Sprague (Sprague, 1969, 1971). 

The Philippine mangrove plant Heritiera Uttoralis (Steraliaceae) has been used as a fish and spearhead poisoa Crude extracts of this plant were shown to be toxic to the fish Tilapia nilotica. Four novel sesquiterpenes of the cadinane type with an unusual oxygenation pattern and an aromatic ring have been previously reported. A fito novel sesquiterpene of this type which was assigned the name Vallapianin has been identified. The structure elucidation of Vallapianin is reported. 

In 1985, Lho (6,7) reported the isolation from the chloroform extract of a novel cadinane sesquiteipene with an unusual oxygenation pattern and an aromatic ring. This compound was assigned the name heritol GI)- Heritol demonstrated ichthyotoxicity (7) to Tilapia nilotica fingeriings (25-35 mm length, 0.05-0.25 g dry weight) at a concentration of 20 ppm (90 min).
