SUMMARY 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 .
