Abstract
Mercury(II) toxicity experiments with green algae are complicated by the fast reduction and evaporation of Hg. A Hg buffer system is described, which considerably stabilizes the Hg(II) concentration in test solutions. The Hg buffer consists of mercury(II) chloride and N-methyliminodiacetic acid (MIDA). Dissociation of Hg-MIDA complex compensates for loss of Hg. With this system experiments were performed with Hg(II) concentrations between 0.02 and 2.0 mg I−1 at temperatures between 15° and 30°C. No effect of MIDA on the growth of the green alga Scenedesmus acutus was detected.
