| Popis: | Cells of Phaeodactylum tricornutum were exposed to 0·12 ppm Hg (containing 203Hg as a tracer in a 3·5% NaCl solution and in dilute culture medium of the same salinity. Radioactivity measurements indicated that mercury uptake by the cells was comparable in both solutions, and that less than 2% of the sorbed mercury was in the pigments, as determined by methanol extraction. The fluorescence of the cells, however, was decreased by either the presence of mercury or the absence of nutrients. |
