Title: Study on AVS and SEM in surface sediment of the Yellow River Estuary
Abstract: Acid volatile sulfides (AVS) and simultaneously extracted metals (SEM) of 11 surface sediment samples collected from the Sea Area of the Yellow River Estuary were determined. The AVS, SEM, SEM-AVS and their distributions were analyzed. The result shows: AVS in the surface sediment of the sea area was between 0.152 and 1.847µmol/g (dry weight), with mean value being 0.935µmol/g (dry weight); SEM in the surface sediment of the sea area was between 0.899 and 1.863µmol/g (dry weight), with mean value being 1.327µmol/g (dry weight);The SEM-AVS in the surface sediment of the sea area was between - 0.594 and 1.365µmol/g (dry weight), with mean value being 0.392µmol/g (dry weight); The metals (SEM) in the surface sediment of the Yellow River mouth probably had some toxicity to the life; the metals (SEM) in the surface sediment of the east and north of the sea areas are safe; the toxicity of metals (SEM) in the surface sediment of the Laizhou bay gradually diminishes.
