| Popis: | Seven sampling stations were identified to determine the status of water quality based on heavy metals concentrations in Cempaka Lake, Bandar Baru Bangi within two sampling periods; June 2010 and August 2010. The objective of the study is to determine the seasonal variations in the lake water quality with respect to heavy metals contamination. Seven parameters of heavy metals were analyzed from the water samples which were collected from the seven different sampling stations at the Cempaka Lake. They are Copper (Cu), Manganese (Mn), Lead (Pb), Zinc (Zn), Iron (Fe), Cadmium (Cd) and Nickel (Ni). The concentrations of these seven heavy metals were determined using inductively coupled plasma-mass spec (ICP-MS) (ELAN 9000). Evaluation of the concentration of heavy metals is carried out based on the NWQS classification.The results are: Cu between 0.0007 to 0.021 mg/L, Mn 0.10 to 0.11 mg/L, Pb 0.001 to 0.002 mg/L, Zn 0.01 to 0.03 mg/L, Fe 1.03 to 4.41mg/L, Cd 0.0001 to 0.0002 mg/L and Ni 0.0013 to 0.014 mg/L. The data obtained from this study were analyzed statistically using the one-way ANOVA, to determine the existence of the relationship based on partial and temporal conditions of the each heavy metal. The results of the analysis on the seven heavy metals in the seven sampling stations found that the concentration of heavy metals is relatively low. Only Fe has high content and in class IV, followed by Mn in class II while the other five heavy metals remain in class I. |
