摘要

Artemia is one of the most important test organisms available for ecotoxicity test. In this study the toxicity of five widely used herbicides formulations including: Paraquat, 2,4-dichlorophenoxy acetic acid (2,4-D), Trifluralin, Glyphosite and Atrazin were compared using ecotoxicity bioindicator, Artemia franciscana. A cute toxicity (48 h LC50) of five herbicides were determined via OECD standard method. Artemia were hatched via standard method and 12 h old nauplii were used for toxicity evaluation of herbicides. Naupliis exposed to Serial concentrations (more than 6 in triplicates) of each herbicid. Mortalities at 12, 24, 36 and 48 hours after exposure were recorded and the LC50 were calculated using Probit software. Results showed that the mortality rate increased along with increasing the exposure time in all herbicide toxicity assays. Besides 48 hours LC50 value of Paraquat, 2,4-D, Trifluralin, Glyphosite and Atarzine calculated at 15.67, 12.93, 11.87, 164.31 and 61.34 mg/L in A. franciscana respectively. Glyphosate showed significantly lesser lethality and toxicity while Trifluralin and 2,4-D showed the highest toxicity in A. franciscana among the examined herbicides. Then for sustainable agricultural activity, especially in areas that runoff water flow to aquatic ecosystems, it is highly recommended to use environmental friendly herbicides like glyphosate as an alternative to highly toxic herbicides like trifluralin, Paraquat and 2,4-D. To the best of our knowledge, this work is the ?rst study comparing the toxicity of highly used herbicides using ecotoxicity bioindicator, Artemia franciscana .

Franciscans中的毒性最高。然后，对于可持续的农业活动，特别是在径流水流到水生生态系统的地区，强烈建议使用像草甘膦这样的环保除草剂，作为Trifluralin，百草枯和2,4-D等毒性除草剂的替代品。据我们所知，这项工作是使用生态毒性生物indicator，Artemia Franciscana比较高度使用过的除草剂的毒性的第一研究。
