为了研究石河口海域的沉积物环境，于2009年9月对石河口海域表层沉积物的Cu、Pd、Zn、Cd、Hg、As含量进行了测定，探讨了重金属含量的分布特征和相关关系，采用地累积指数法和潜在生态风险指数法对重金属的富集程度和潜在生态风险进行了评价。结果表明：Cu和Pd、Cu和Cd、Pd和Cd之间存在显著正相关性。重金属富集程度排序为Cd＞Hg＞Cu＞Zn＞Pd＞As。石河口海域多种重金属潜在生态风险指数属于轻微风险状态。重金属潜在生态风险指数排序为Cd＞Hg＞Pd＞Cu＞As＞Zn，Cd的生态风险指数属中度风险状态，研究区域在一定程度上受到了Cd的污染。
為瞭研究石河口海域的沉積物環境，于2009年9月對石河口海域錶層沉積物的Cu、Pd、Zn、Cd、Hg、As含量進行瞭測定，探討瞭重金屬含量的分佈特徵和相關關繫，採用地纍積指數法和潛在生態風險指數法對重金屬的富集程度和潛在生態風險進行瞭評價。結果錶明：Cu和Pd、Cu和Cd、Pd和Cd之間存在顯著正相關性。重金屬富集程度排序為Cd＞Hg＞Cu＞Zn＞Pd＞As。石河口海域多種重金屬潛在生態風險指數屬于輕微風險狀態。重金屬潛在生態風險指數排序為Cd＞Hg＞Pd＞Cu＞As＞Zn，Cd的生態風險指數屬中度風險狀態，研究區域在一定程度上受到瞭Cd的汙染。

The contents of Cu, Pb, Zn, Cd, Hg in the surface sediments samples in Qinhuangdao Shihe River were measured, in September of 2009. The correlation coefficient and distributed characteristics of heavy metal contents were discussed, The environmental risk was evaluated by using such methods as Sediment Enrichment Factors and Hakanson Potential Ecological Risk Index. The results shows:there is a positive correlation between Cu and Pd, Cu and Cd, Pd and Cd. The order of enrichment of heavy metals:Cd>Hg>Cu>Zn>Pd>As. The potential ecological risk index of heavy metals is a minor risk status. The order of potential ecological risk factor was Cd>Hg>Pd>Cu>As>Zn, Ecological risk factor of Cd is a moderate risk status, The results shows:the investigation area was some extent polluted by Cd.
