Abstract
The heavy metal accumulation in soil to the surrounding area is caused by
distribution of pollutant through wind from anthropogenic activity. The soil can
be toxic when it contains non-essential heavy metal. The objectives of this study
are to assess the copper (Cu), zinc (Zn) and lead (Pb) concentrations and to
determine the contamination of heavy metal with contamination factor and goo
accumulation index (lgeo). Soil samples were taken at depth of 10 em at different
distances from palm oil mill, 0.5 km, 1 km, 2 km, 3 km, 4 km, and 5 km. The
samples were air dried for 1 week, sieved, grinded and digested with nitric acid
(HN03) after heating in the furnace at 450°C for 16 hours or overnight. Then, the
samples were analysed using Flame Atomic Absorption Spectroscopy (FAAS) to
determine the concentrations of the selected heavy metal studied. Three replicates
for each sample were used to obtain the average value. The mean concentration
obtained for the whole sampling locations were found in the ranged of 17.0 to
51.0 mg/kg for Cu, 12.0 to 43.0 mg/kg for Zn and 0.8 to 21.6 mg/kg for Pb. In
conclusion, Cu had the highest concentration compared to Zn and Pb in the top
soil. Based on statistical analysis using contamination factor and goo
accumulation index, the studied area is moderate contamination by the heavy
metal especially for Pb followed by with Cu and Zn.
