Abstract
Several species of algae (axenic) and aquatic vascular plants were evaluated for effectiveness in removal of pesticides from water. Pesticides with 14C were utilized to determine plant uptake and molecule degradation. Herbicide concentrations below toxic levels were used; however, these were many times greater than natural residue levels encountered in surface water. Herbicides were metabolized by various aquatic plants. Metabolites as well as the herbicide were released to the culture medium. Metabolism was rapid, particularly with algae. Algae and aquatic vascular plants contribute to the removal of pesticides from water and metabolize the chemicals to less active compounds in the environment. (Author Modified Abstract)
