Title: | Surfactant (Genapol OX-80) toxicity to Selenastrum capricornutum | Authors: | Anastácio, P. M. Holten Lützhøft, H. -C. Halling-Sørensen, B. Marques, J. C. |
Keywords: | Crayfish | Issue Date: | 2000 | Citation: | Chemosphere. 40:8 (2000) 835-838 | Abstract: | A non-ionic surfactant (Genapol OX-80) was proposed as a means of reducing destructive crayfish activity in rice. In order to study the toxicity of this product on algae, a test in accordance to the ISO 8692 protocol (1989) was performed. The growth inhibiting effect of the pure formulation of Genapol OX-80 was studied on Selenastrum capricornutum in the concentration range of 0.01-1.0 mg/l. The result indicated a 72 h EC50-value of 0.5 mg/l. The suggested field concentration of approximately 50 mg/l is therefore two orders of magnitude above the algal EC50-value. From our findings it is expected that the impact on the rice field algae will not be negligible. | URI: | https://hdl.handle.net/10316/5450 | DOI: | 10.1016/S0045-6535(99)00275-1 | Rights: | openAccess |
