摘要: Abstract Brunei Bay is one of the most important marine environments East Malaysia (South China Sea), covering many productive ecosystems with activities including fisheries, tourism, and main shipping lanes for petroleum transfers. Evaluation sources distributions steroids in surface sedimentary organic matter was carried out by gas chromatography–mass spectrometry (GC–MS). The concentrations total identified sterols (TIS) ranged between 0.81 12.69 μg g−1 dry weight, sterones were 0.11 5.66 μg g−1 weight. coprostanol level comparatively low (
