چکیده انگلیسی
Ecotoxicological monitoring of intertidal sediments was performed for 5Â years after the Hebei Spirit oil spill in Taean, Korea. Sediment toxicity was observed on most of the beaches 4Â months after the spill and later decreased rapidly to nontoxic levels 8Â months after the spill. The concentrations of total polycyclic aromatic hydrocarbons (TPAHs) in the sediments ranged from 2 to 530,000Â ng/g during the monitoring. More than half of the samples exhibited significant toxicity 5Â years after the Hebei Spirit oil spill. Using a logistic regression model, the median lethal concentration of TPAHs to amphipod Monocorophium uenoi was estimated to be 36,000Â ng/g. From the 63 chemistry and toxicity data, the effect range-low, effect range median, threshold effect level, and probable effect level were derived to be 3190, 54,100, 2480, and 29,000Â ng/g, respectively. The relative compositions of the PAH groups indicated that the weathering process is still ongoing.
