Abstract Several species of algae and aquatic vascular plants were evaluated for effectiveness in removing pesticides from water. Pesticides with 14C-label were used to determine uptake and degradation. It is evident that aquatic algae and vascular plants do remove pesticide residues from water. This might help explain why herbicide residues have not accumulated in surface water to dangerous levels. In general, submerged aquatic plants were not as effective in removing the herbicides as emerged species. The various algae tested were not equally effective in sorbing the pesticides. Scenedesmus was particularly effective in this respect. The pH of the suspending medium proved to be important in the case of 2,4-D. It was demonstrated that once sorbed, these pesticides were metabolized by the various aquatic vascular plants and algae.
