Influence of Humic Acid on Toxicity of Malachite Green to Aquatic Plant

Article Preview

Abstract:

In this study the toxicity of malachite green (MG) to aquatic plants (rice seeds) and impact by Aldrich humic acid (HA, used as model dissolved organic matter) were investigated with the germination rate of rice seeds. Results showed that germination rate was decreased from 77% to 1% with the increasing concentration of MG (0-2000 mg L-1), and the obvious dose-response relationship was observed. At the same time, the germination rate was improved from 33% to 50% after the addition of HA (1-500 mg L-1) at the fixed concentration of MG (1000 mg L-1).
