英文摘要: There is a high degree of heavy oil partitioning into marine sediments when an oil spill occurs. Contaminated sediment, as an endogenous pollution source, can re-pollute overlying water slowly. In this study, a static oil release process and its effects in marine sediment was investigated through a series of experiments with reproductive heavy oil-contaminated marine sediment. The oil release process was accurately simulated with a Lagergren first-order equation and reached equilibration after 48 h. The fitted curve for equilibrium concentration (C0) and first-order rate constant (k1) for sediment pollution levels exhibited a first-order log relationship. The instantaneous release rate ([Formula presented]) was also calculated. The C0 increased with increases in temperature and dissolved organic matter (DOM), and decreasing salinity. The k1 increased with temperature, but was not affected by DOM and salinity. These results can be used to better understand the fate of heavy oil in contaminated sediments of the Bohai Sea. © 2017 Citation statistics:
