| Summary: | A study has been carried out to determine the distribution of aliphatic hydrocarbons in surface soils of
Kuantan City, Pahang, Malaysia. Thirty soil samples (0-15cm depth) were collected from area around Kuantan City
covering town center, schools, recreation areas and industrial zones. Hydrocarbons were extracted with
dichloromethane using ultrasonic agitation technique and fractioned with silica-alumina column. Characterization of
individual hydrocarbon components was carried out using Gas Chromatography – Flame Ionization Detector (GCFID).

. Carbon preference index (CPI) values for higher plant wax n-alkanes varied between 0.39 and 1.40,
with a mean value of 1.11. No significant correlation between soil organic matter content and the concentrations of nalkanes
was observed. Results indicated that the aliphatic hydrocarbons were from both biogenic and anthropogenic
sources. |
