Abstract

Total petroleum hydrocarbon (TPH), total organic carbon (TOC) content and particle size were investigated in mud clam (Polymedosa erosa) and sediment in the coastal area of Putatan and Tuaran, Sabah. Mud clams and sediments were collected by hand-picking and trowel in five stations respectively for both coastal area. Mud clams and sediment samples were extracted for TPH using standard method APHA 5520 and analyzed using UV/VIS spectrophotometer. The determination of TOC content was based on United Nations Environment Programme (UNEP)/ MAP Athens (2006). The overall range of TPH concentrations in mud clam and sediments in both study areas were recorded at 0.72 – 2.16 mg/kg dw and 0.15 – 0.62 mg/kg dw Miri crude oil equivalents, respectively. The overall mean and range of TOC content from coastal area of Putatan and Tuaran were 9.30% (5.37 – 15.82%) and 7.98% (4.21 – 12.93%) respectively and sandy particles are majority in these two sites. In the meantime, the statistical analysis by Pearson correlation showed a moderately positive correlation with coefficient for TPH concentration in mud clam and sediment (r=0.6340 for Putatan; r=0.6978 for Tuaran), meanwhile showed a strong positive correlation for TPH concentration and TOC content in sediment (r=0.9637 for Putatan; r=0.9340 for Tuaran). Therefore, TOC can be used as the screening for TPH in sediment for both areas.
