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 Samples were withdrawn at 0 (control), 1, 3, 5, and 7 d after each herbicide treatment, and growth was determined by measuring dry weight (DW), or chlorophyll-a content by spectr...

| description | 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 Samples were withdrawn at 0 (control), 1, 3, 5, and 7 d after each herbicide treatment, and growth was determined by measuring dry weight (DW), or chlorophyll-a content by spectrophotometry (CAS) or by fluorometry (CAF). CAF was more sensitive for algal growth measurements than CAS or DW, but all could be used as algal growth indicators. Because higher herbicide concentrations produced a negative growth rate, particularly after 1 d exposure and the algae showed an ability to recover with time, the effect of herbicides on algae would be more accurately determined after at least 3 d exposure. The differences in EC values obtained from algal toxicity tests depending on whether biomass or growth rate was taken as the determinand are discussed. Recultivated A. flos-aquae, after exposure to atrazine, showed a higher growth rate than the untreated control during a 10 d test period, possibly due to selectivity towards more vigorous, surviving cells or an altered metabolic rate in the surviving algal cells. Difficulties with the techniques used to measure algal responses to toxicant are listed. |
