翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Water soluble fraction ： ウィキペディア英語版 Water soluble fraction The water Soluble fraction (W.S.F.), sometimes termed the water associated fraction (W.A.F.), is the solution of low molecular mass hydrocarbons naturally released from petroleum hydrocarbon mixtures in contact with water. Although generally regarded as hydrophobic, many petroleum hydrocarbons are soluble in water to a limited extent. This combination often also contains less soluble, higher molecular mass components, and more soluble products of chemical and biological degradation.〔Harrison G, Lamont N. Simulated Time-based Studies To Evaluate Changes In Crude Oil Composition Through Evaporation And Biodegradation. Wessex Institute of Technology Oil and Hydrocarbon Spill Conference Greece 2002〕 ==Toxicity== Low molecular mass compounds account for much of the toxic nature of hydrocarbon spills. In particular, benzene, toluene, ethyl benzene and the xylenes (BTEX) are of great environmental interest due to their availability to organisms. This availability, also influenced by volatility and reactivity, impacts on biodegradation and bioremediation in water and soil environments, with even dissolved components within pore water considered bioavailable.〔Megharaj M, Ramakrishnan B, Venkateswarlu K, Sethunathan N, Naidu R.
