多氯联苯(PCB_(1254))对栉孔扇贝渗透调节的影响
Effects of PCB_(1254) on Osmotic Adjustment of the Scallop Chlamys ferrari
摘要
Abstract
In order to provide monitoring criterion for scallops healthy breeding in organic matter pollution area of China's coastal,the effects of PCB1254(0.5,1.0,10.0 and 50.0 μg·L-1) on osmotic adjustment of the scallop Chlamys ferrari were studied.The results showed that the osmotic pressure of hemolymph changed significantly under the PCB1254 of all concentrations except for the 0.5 μg·L-1treatment.The osmotic pressure increased significantly during all experimental time in 1.0 μg·L-1,while the osmotic pressure increased soon and then decreased nearly to the seawater control levels in 10.0 μg·L-1 and 50.0 μg·L-1 groups.The Na+-K+-ATPase activity of gills of Chlamys ferrari increased significantly in low concentrations(0.5 μg·L-1 and 1.0 μg·L-1)of PCB1254,but it was restrained by high concentrations of PCB1254 during all sampling time.It concluded that the metabolic production produced by PCB1254 could cause the excitation response and the changes of cell membrane of the scallop Chlamys ferrari,so the osmotic pressure and Na+-K+-ATPase activity changed.The changes of Na+-K+-ATPase activity showed certain regularity,it could reflect the whole ability of detoxification of the organism as well as the damage degrees caused by PCB1254,so it could be used as the evaluated biomarker for toxicity of PCB1254.关键词
