The PAHs distribution and it source of contimination in sedimen at Kerteh River, Terengganu

Abstract

Soil sample were taken from 10 stations in Sungai Kerteh ru:id 3 stations at Port of Kerteh have taken soil samples to determine the level of Polycyclic Aromatic Hydrocarbon content, PAH. Sampling was conducted at two times that on the 26-28 April 2010 for the first sampling. For the second sampling conducted on the 21-23 October 2010. Sample were extracted by Soxhlet method and used to separate Coloum Packed were used to separate T AH and P AH, before analyzed using gas-flame ionization detector chromatograph, GC-FID was used to obtain readings. A total of 16 species of Polycyclic Aromatic Hydrocarbon, PAH and 35 species of Total aliphatic hydrocarbon, TAH has been used as a benchmark to look for a compound found in soil samples taken in the area of sampling. Total Aromatic Hydrocarbon, T AH found in this area is in the range of ND - 14839.601 μgig to the river in the port area mean while amount that is due to the content found within the ND-2315.420 μgig for the first sampling. For the second sampling of content is found in the River Kerteh from ND - 24268.442 μgig and ND-215583μg/g. Through this study, the type of distribution and the fraction of PAH molecules by the presence of the indicator member, or from natural occurring sources of pollution. From these studies also find that the area is still safe and accepted level of pollution does not exceed the highest level.
