Organic Matter in the Sediments in Hiro Bay Near to Outlet of Pulp Mill Waste Water

Abstract

The sediments in Hiro Bay under by the pulp mill effluent water analyzed by gas chromatography and mass spectrometry. The sediments were extracted with chloroform (CHCla: CI-13OH=2: 1). The chloroform extract was then concentrated under reduced pressure. The concentrated chloroform extract was fractionated on silica gel column. Each fraction was then analyzed in terms of gas chromatography and mass spectrometry (GC-MS).
Identified compounds. were longiforene, isopimaradiene, dehydroabietane, retene, fatty acids (normal branched CH C164H16411 C1841, C1842) resin acids (dehydroabietic acids), aliphatic hydrocarbons (normal Cl228), and sterols t (cholesterol, β-sitosterol). The distribution of fatty acids, hydrocarbons, or terpenes in the sediments in Hiro Bay was elucidated.
