Abstract

Dividing and nondividing cell populations of Chaetoceros costatum Pavillard were placed in light; nondividing populations were also placed in the dark, and one population was killed by formalin. No difference in(203) Hg uptake was seen in nondividing cells in the light and dark, while cells accumulated about 2 times as much(203) Hg as living cells, presumably by surface adsorption. Dividing cells in light accumulated(203) Hg longer than did nondividing cells, indicating the possibility of some active uptake of Hg.

摘要

将中肋骨条藻（Chaetoceros costatum Pavillard）的分裂细胞群和非分裂细胞群置于光照下；非分裂细胞群也被置于黑暗中，并且有一群细胞被福尔马林杀死。在光照和黑暗条件下，非分裂细胞对（203）汞的吸收没有差异，而这些细胞积累的（203）汞大约是活细胞的2倍，推测是通过表面吸附。光照下的分裂细胞积累（203）汞的时间比非分裂细胞长，这表明存在某种主动吸收汞的可能性。
