| 摘 要： | 该文研究了海水中Cu、Pb、Cd浓度分别为0.5 mg/L时，总有机碳(TOC)浓度、种类对牙鲆(Paralichthys olivaceus)内脏、肌肉、鳃组织Cu、Pb、Cd蓄积的影响。结果表明：当海水TOC种类相同时，随TOC浓度升高，牙鲆内脏、肌肉、鳃组织Cu、Pb、Cd蓄积量均明显下降；当海水TOC浓度相同时，孔石莼分泌物比牙鲆分泌物更能降低牙鲆各组织Cu、Pb、Cd蓄积量。研究表明：孔石莼、牙鲆分泌物均能降低Cu、Pb、Cd的生物有效性；TOC浓度、种类变化对牙鲆各组织Cu、Pb、Cd蓄积分配均无影响，重金属含量大小顺序均为：内脏＞鳃＞肌肉。内脏团、肌肉中3种重金属蓄积量大小顺序为Cu＞Pb＞Cd；鳃中3种重金属蓄积量顺序为Pb＞Cu＞Cd。

| Abstract: | Effects of species and concentration of total organic carbon(TOC) in the seawater on the accumulation of copper,lead and cadmium in visceral mass, muscle and gills of Paralichthys olivaceus when the copper,lead and cadmium concentrations were maintained at 0.5 mg/L, respectively were studied. It was demonstrated that when the species was same, the copper accumulation reduced significantly with the increase of TOC's concentration; when the concentration of TOC was same, Ulva pertusa excretion could reduce the copper accumulation more than Paralichthys olivaceus. It was demonstrated that all the excretions of Ulva pertusa and Paralichthys olivaceus complexed with copper,lead and cadmium, respectively were not well available for fish uptake; the species and concentration of TOC in the seawater could not affect the accumulation order in the tissues of Paralichthys olivaceus, the accumulation order of heavy mentals in the fish tissues was visceral mass>gills>muscle. The accumulation order of three heavy metals in the tissues of visceral mass and muscle was Cu>Pb>Cd; The accumulation order of three heavy metals in the tissues of gills was Pb>Cu>Cd. |
