Abstract

Drilling activities to extract natural gas from the bottom of the sea can cause the release of several types of heavy metals into the marine water and seabed sediment. Excessive heavy metals concentrations in the marine environment could cause toxicity to the fish and other marine life. Subsequently, the heavy metals will enter into human body when the contaminated fish is consumed by human. Some chemicals present in the marine water will settle down onto the seabed sediment. This study aimed to study the trends of heavy metals distribution in seabed sediment at Golok Central and Golok Barat gas fields, Sarawak from 2010 to 2012. The concentrations of Cd, Cr, Ni, Pb, Co, Ba, Cu, and Zn in seabed sediment were analysed. The result of the analysis showed that the average concentrations of heavy metals in seabed sediment at Golok Central and Golok Barat gas fields from 2010 to 2012 were significantly different (P < 0.05). Comparison between means of concentrations of heavy metals in seabed sediment at different locations (Golok Central and Golok Barat gas fields), however, showed no significant difference. Comparing to the EIA baseline data, most of the heavy metals concentrations exceeded the baseline data.
