| 摘 要： | 本所在渤海湾污染调查中发现河口区沉积物已受到不同程度的重金属污染,如Zn在大沽河口外表层底质中的浓度已达131.5ppm~1)远高于本底值(70ppm)。渤海湾由于水质肥沃、饵料丰富,因而是我国北方海区的重要渔场之一。为研究近海河口区饵料细胞密度与污染物

The relationship between cell density of Phaedactylum tricornutum and bio-accu-mulation and excretion of zinc-65 in the algae |
| |
| Abstract: | The effects of different cell densities of Phaedactvlum tricornutum on bio-accumulation and excretion of 65Zn in the algae have been studied.The experimental results show that concentration of 65Zn in low density group of the algae from sea water is greater than that in high density group.Concentration factors of three groups are above 104, and the C. F. of the lowest density-group is the greatest, 4.4×104. The mechanism of accumulating 65Zn by unicellular algae is discussed. |
