“…On December 7, 2007, the worst oil spill occurred about 10 km off the Taean coast, in Korea, when the tanker Hebei Spirit foundered and released approximately 10,900 tons of crude oil (Hong et al, 2012a(Hong et al, , 2014Yim et al, 2012). Several previous studies indicated that the water quality, bioaccumulation, and benthic community of the Taean coast appeared to be fairly (or almost fully) recovered in five years after the Hebei Spirit oil spill (HSOS) (Hong et al, 2012a;Ji et al, 2011;Jung et al, 2011;Kim et al, 2010;Lee et al, 2011Lee et al, , 2013aYu et al, 2013). However, coastal sediments in the vicinity of an oil spill site are subject to a relatively long history of contamination, particularly in semi-closed sheltered areas.…”
