| Abstract | The influence of 0 multiplied by 1, 1 and 10 mg kg super(-1) of the terrestrial herbicides atrazine, trifluralin, MSMA and paraquat on the species composition and standing crop of algal periphyton was assessed using artificial streams. For each herbicide, two experiments were performed: one using algae from a pristine spring and another using algae from a stream heavily influenced by agricultural runoff. Also, in each experiment, 0 multiplied by 01 mg kg super(-1) of the test herbicide was maintained in the water of half the streams during a three-week period prior to the application of the 0 multiplied by 1/1/10 mg kg super(-1) treatments in an attempt to induce development of a resistant community. Atrazine caused the most extensive damage. Rhopalodia, Phormidium and Cladophora were severely inhibited by 1 and 10 mg kg super(-1), and these treatments caused a large biomass reduction. Trifluralin decomposed rapidly in the streams and had no toxic effect. MSMA and paraquat caused reductions in several filamentous cyanobacteria, but these effects were less serious than those of atrazine. Contrary to expectation, the spring community seemed more resistant than the stream community to both atrazine and paraquat. Also, while the 0.01 mg kg-t treatment caused detectable reductions in several species, there was no evidence that it induced resistance to any of the herbicides. |
