Variation and sources of sterols in Kuala Selangor, Selangor

This study explores the role of sterols as lipid biomarkers to assess organic matter variations and their sources in surface sediments of Kuala Selangor, Selangor which involved extraction procedures and sterol compounds analyzed using GC-MS. Ten sterol compounds were found in the samples with phyto...
