Metal distribution and contamination level around selected parking area / Nurul Asyikin Abd Halim

Soil contain various types of heavy metals. Heavy metal is the natural elements that
are found at various background level at a different place throughout the world due to
its various concentration. Heavy metal can cause fatal effect toward human and
environment if exposed in high concentration. The objectives of this study were to
determine the concentration and distribution of selected heavy metal at selected
parking area and to evaluate the level of heavy metal contamination based on
contamination factor CF and enrichment factor EF. Heavy metals that were analyzed
were Copper(Cu), Iron(Fe), Nickel(Ni), Lead (Pb) and Zinc (Zn). In this study the
sample was dried in microwave and was digested by using Acid Digestion method.
The sample concentration was then analyzed using Inductive Couple Plasma- Optical
Emission Spectroscopy (lCP-OES). The mean concentration obtained from the whole
sampling site were 19.8 and 11.1mg/kg, 5072 and 13529 mg/kg, 2.8 and 1.2 mg/kg,
9.6 and 11.1 mg/kg, 44.7 and 37.3 mg/kg for Cu, Fe, Ni, Pb, Zn in rural parking
Kelantan and Pahang and for suburban Cu, Fe, Ni, Pb, Zn were 11.5mg/kg and 16.2
mg/kg, 10707 mg/kg and 8244 mg/kg, 3.6 mg/kg and 1.1 mg/kg, 19.7 mg/kg and 6.7
mg/kg, 26.6mg/kg and 9.2 mg/kg respectively. In conclusion Fe have the highest
concentration in both soil at rural and suburban parking area compared to Cu, Ni, Pb
and Zn . Based on data obtained from the contamination factor the study area were
severely contaminated with heavy metal and significantly enrich by heavy metal due
to anthropogenic source
