| Popis: | An interaction with fine mineral particles accelerates the removal and dispersion of stranded oil from spill impacted coastal regions. Shaker flask experiments under simulated environmental conditions were conducted to measure the significance of this intrinsic oil spill remediation process for the coastal marine environment. Results show that numerous crude and refined oil products produce stable micro-aggregates. Experiments conducted with a weathered crude oil over a 56 day period (10 °C) indicated that oil-mineral fine interactions stimulated bacterial growth and the rate and extent of hydrocarbon degradation. At the end of the experimental period, only 25% compared to 48% of the n-alkane fraction (n-C15 to n-C35) remained in flasks treated with and without mineral fines, respectively. Similarly, the percent total target aromatics remaining was substantially lower in mineral fine amended samples (8%) than in oiled controls (25%). These results support the application of shoreline clean-up techniques b... |
