DOIAbstract
The surface sediments from the Bohai Sea (BS) and the northern Yellow Sea (NYS) were analyzed for acidvolatile sulfide (AVS) and simultaneously extracted metals (SEM) to assess the sediment quality. The results indicated that>60% of the samples were found to have possible adverse effects on aquatic life in the BS based on the difference between the concentrations of AVS ([AVS]) and SEM ([SEM]), and the corresponding percentage in the NYS was<25%. Nevertheless, there was no indication of adverse effects for all the BS and the NYS samples when the total organic carbon (TOC) concentration was introduced in the sediment quality evaluation with [AVS] and [SEM]. The grain size composition, TOC, water content and pH all had significant influence o...
