Growth response of freshwater algae, Anabaena flos-aquae and Selenastrum capricornutum to atrazine and hexazinone herbicides

The toxicities of atrazine and hexazinone to the algae Anabaena flos-aquae and Selenastrum capricornutum were determined. Samples were withdrawn at 0 (control), 1, 3, 5, and 7 d after each herbicide treatment, and growth was determined by measuring dry weight (DW), or chlorophyll-a content by spectr...
