Bentazon Triggers the Promotion of Oxidative Damage in the Portuguese Ricefield Cyanobacterium Anabaena cylindrica: Response of the Antioxidant System.

The article presents a study that provides comprehensive and comparative analysis of the enzymatic antioxidant defense systems of Anabaena cylindrica, exposed to the herbicide bentazon, an active ingredient of basagran. It highlights the significant occurrence of the organisms on the rice fields of Portugal. Obtained results of the study suggest that the alterations of antioxidant systems of the organisms might be a useful biomarkers of bentazon exposure and explains the oxidative stress pathways of bentazon.
