　　海水水质直接影响养殖业发展及海洋产品品质，受到越来越多关注。为了解扇贝养殖区域海水水质状况及对扇贝品质的影响，采用分期取样的方法，在莱州湾某扇贝养殖区采集表层海水样品，以非养殖区为对照，分析其pH、营养盐、COD、Cu及Zn含量；同时，采集扇贝幼体、成体，分析Cu、Zn在闭壳肌（贝柱）中蓄积。结果表明：研究区域海水中无机氮含量较高，接近0.30 mg/L，不同时间其含量和组成差异显著，10月海水中无机氮以硝态氮为主，含量极显著高于以氨态氮为主的6月(P<0.01)。不同时间，不同采样点海水中无机磷含量均小于0.02 mg/L，差异不显著。COD、Cu及Zn含量均为6月显著高于10月(P<0.05)，未超出二类海水水质标准值。COD、Cu及Zn三者间呈极显著正相关(P<0.01)，表明它们可能来自同一污染源。扇贝对Cu、Zn的富集能力较强，对Zn富集能力大于Cu。尽管扇贝闭壳肌中Cu、Zn含量在相关标准值之内，但Cu、Zn富集程度分别达到了1.06、0.821，所以，扇贝养殖过程中Cu、Zn等重金属在体内蓄积应引起更多关注。

Seawater quality can affect sea fishing and seafood quality, and thus has received more and more concerns. In order to know the seawater quality in Argopectens irradias fishing area and the influence of seawater on the quality of Argopectens irradias, the quality of surface seawater samples collected from an Argopectens irradias fishing area and un-fishing area in Laizhou Bay at different times was assessed, involved pH and nutrients, chemical oxygen demand (COD), Cu and Zn concentrations. Results showed that, in study area, the inorganic N concentration was high relatively, and approximately reached 0.30 mg/L. Nitrate-N was the main component of inorganic N of seawater in October, which was significantly higher than that in June in which the main inorganic N was ammonia-N (P<0.01). In different sampling sites, the inorganic P concentrations at different times were all less than 0.02 mg/L, and changed insignificantly. COD, Cu and Zn concentrations were all less than the value of the second grade seawater standard, and were significantly higher in October than that in June (P<0.05). The significant positive correlation among COD, Cu and Zn indicated that they probably came from the same polluted source (P<0.01). Argopectens irradias had high bioconcentration capability of Cu and Zn, and the capability of Zn was greater than that of Cu. Although the concentrations of Cu and Zn were both less than the associated standard values, the accumulation extents of Cu and Zn were 1.06 and 0.821, respectively. Therefore, heavy metals accumulation in Argopectens irradias should be aroused more concerns in future.
