Abstract

The effective concentrations of copper and cadmium which reduced the population growth of Dunaliella minuta by 50% after 96 h of static exposure, were determined to be 7.57 microM Cu and 0.34 microM Cd. Short-term static exposure to both metals indicated that their combined action is antagonistic with respect to growth of this chlorophyte. Additionally, long-term exposure to low levels of Cu or Cd led to the acquisition of tolerance towards Cu and Cd, respectively, and co-tolerance towards Cu.

摘要

通过静态暴露96小时后使微小杜氏藻种群增长降低50%的铜和镉的有效浓度，经测定分别为7.57微摩尔/升铜和0.34微摩尔/升镉。对这两种金属的短期静态暴露表明，它们对这种绿藻生长的联合作用是拮抗的。此外，长期暴露于低水平的铜或镉分别导致对铜和镉耐受性的获得，以及对铜的共同耐受性。
