<p>A method for reducing the sediment toxicity of a composition, which includes a mixture of hydrocarbons, the mixture including hydrocarbons having a boiling point above about 270 °C and below about 340 °C, is provided. The method includes the steps of fractional distilling of the composition and collecting a fraction of hydrocarbons having a boiling point above about 270 °C and below about 340 °C. The sediment toxicity may be towards (Leptocheirus plumulosus) and the fraction of hydrocarbons may have a median lethal concentration (LC50) of more than about 500 mg/kg and a Sediment Toxicity Ratio (STR) of greater than about 1.</p> |
