Effects Of Heavy Metals From Urban Runoff On The
Receiving Water Sediments

Abstract
The concentrations of heavy metals in the suspended and bed sediments in the
urban receiving water, i.e., Kranji and MacRitchie reservoirs in Singapore were
investigated. Distribution of heavy metals in the suspended sediments of different
grain size was determined. The results show that more than 50 % of heavy metals
in the aquatic system are carried by suspended sediments in the urban runoff to
the receiving waters. Heavy metals are most likely to be transported by particles
of grain size > 1.2 urn. Elevated concentration of heavy metals in the interstitial
water of the bed sediment are potential threat to the quality of water and aquatic
life.
