The surface sediments from Laizhou Bay (LB) and the coastal sea around Zhangzi Island (ZI) were analyzed for acid-volatile sulfide (AVS) and simultaneously extracted metals (SEMs) to assess the sediment quality. These two areas, especially LB, are important mariculture bases in China and are significantly affected by the Yellow River. The concentrations of AVS ([AVS]) and SEM ([SEM]) varied in the ranges 0.71-11.03 and 0.10-0.74 μmol g(-1) dry weight, respectively. [AVS] was generally low in the river outlet area and increased in the seaward direction in LB. [AVS] was significantly and positively correlated with TOC. [SEM] was significantly and positively correlated with TOC, the water content of sediment and the fine sediment fraction and it was significantly and negatively correlated with coarse sediment fraction. The obtained results suggest that the surface sediments of LB and ZI were of high quality and not likely to cause negative effects on their ecosystems.
莱州湾（LB）和獐子岛（ZI）沿海海域的表层沉积物进行了酸可挥发性硫化物（AVS）和同时提取金属（SEMs）分析，以评估沉积物质量。这两个地区，特别是 LB，是中国重要的海水养殖基地，受到黄河的显著影响。AVS([AVS])和 SEM([SEM])的浓度分别在 0.71-11.03 和 0.10-0.74 μmol g(-1)干重范围内变化。LB 河口地区的 AVS([AVS])一般较低，向海方向增加。AVS([AVS])与 TOC 呈显著正相关。SEM([SEM])与 TOC、沉积物含水量和细颗粒部分呈显著正相关，与粗颗粒部分呈显著负相关。研究结果表明，LB 和 ZI 的表层沉积物质量较高，不太可能对其生态系统产生负面影响。
