Abstract

Human body may be directly exposed to heavy metal in semi-urban soils
through ingestion, inhalation and dermal contact of soil particle. A total of 12
samples were collected from semi-urban area of the roadside of Jalan Berlian,
Jengka Pahang. This study aimed to determine the concentration of selected
metal and to evaluate the health risk assessment (HRA) from different exposure
pathways. Concentration of Cd (1.00 mgkg-1) in the soils were similar to the
control soil value, whereas Cr (22.08 mgkg-1), Pb (38.33 mgkg-1) and Zn (85.25
mgkg-1) were exceeded the control value. Both non-carcinogenic and
carcinogenic were assessed using Hazard Index (HI) and Life Time Risk (LCR)
respectively. All the value is categorized under acceptable value except
exposure of Cr via dermal contact. In addition, Contamination factor (CF)
calculation suggests there was very high Cr contamination. Further study should
be done to evaluate other metal elements such as As and Cu, which may give
bad effect if it's being exposed to human especially in high concentration.
