Penunjuk Biolipid di Muara Sungai Selangor, Selangor: Analisis Prinsip Komponen (PCA) Sterol dan Alkohol Lemak (Lipid Biomarkers in Estuary of Sungai Selangor, Selangor: Principal Component Analysis (PCA) of Sterols and Fatty Alcohols)

A total of 34 surface sediment samples were taken from Sungai Selangor estuary to identify sources and variations of sterols and fatty alcohols. Samples were then extracted and the compounds were analyzed using gas chromatography-mass spectrometry (GC-MS). As a result, 10 sterol compounds and 18 fatty alcohol compounds were determined presence in the samples. Generally, the study area is dominated by phytosterols, long chain fatty alcohols...
