The increase in length of apices of Ascophyllum nodosum (L.) Le Jolis was measured in paired combinations of Cu, Hg, and Zn. Significant antagonistic effects appeared with exposure to Cu + Zn after 3 days (P < 0.001), and with Hg and Zn after 4 days (P < 0.01). When Cu and Hg were combined, only a weak antagonistic effect was indicated after 7 days of exposure. It is supposed that the observed detoxificating effect of Zn to Cu and Hg is partly related to the relative number of ions present. |
