Pollution status of the Sungai Skudai river system through heavy metals

This study was conducted to assess the extent of heavy metal pollution in the Sg. Skudai river system. A total of 16 monitoring stations were established along the Sg. Skudai river system. Water, plants (Phragmites karka) and sediment samples were collected from the sampling points along the downstr...

Sanitary engineering This study was conducted to assess the extent of heavy metal pollution in the Sg. Skudai river system. A total of 16 monitoring stations were established along the Sg. Skudai river system. Water, plants (Phragmites karka) and sediment samples were collected from the sampling points along the downstream route of the river near the industrial zones.

Water quality parameters such as temperature, pH, DO, BOD and COD were monitored to determine their status in relation to the health of the river ecosystem.

Then trend of heavy metals in water of the Skudai River system is Zn>Cu>Ni>Cr>As>Pb>Hg>Cd, in plants is Zn>Cr>Cu>Pb>Ni>As>Hg>Cd and in sediments is Zn>Cr>Cu>Pb>Ni>As>Hg. All results were reported between 15-20 % of the standard deviation. Correlations exist for chromium and copper from the correlation analysis between plant and water and plant and sediment.
