The natural sediment from Sungai Terengganu was used in this study to evaluate
metal toxicity testing on Chironomus kiiensis. The aims of this study were to determine
the survival rate of Chironomus kiiensis and to calculate correlation between
concentration in Sungai Terengganu sediment and mortality of Chironomus kiiensis.
The sediment from five sampling points were put in glass beaker with Chironomus
kiiensis. Metal concentration, total organic carbon and particle size were analyzed
using the same sediment. The emergence rate and mortality rate of Chironomus
kiiensis was observed every day during the experiment was conducted. The water
parameter is being control to make sure that the water was not contaminate with the
excessive food. Observation effects on Chironomus kiiensis in sediment toxicity shows
different change in emergence rate and mortality within the station. Hence, metal
concentration, total organic carbon and particle size analysis correlate with the
mortality of Chironomus kiiensis.
