Additional information
In a 72-hour algal growth study, cultures of Desmodesmus subspicatus were exposed to Reaction mass of Fatty acids, tall-oil, compds. with oleylamine and Fatty acids, C18-unsatd., trimers, compds. with oleylamine at nominal concentrations (loading rate) of 0 (control), 0.1, 0.32, 1.0, 3.2, 10, 32, 100 mg/L under static conditions for in accordance with the OECD 201 guideline. The water pH, temperature and lighting intensity were all maintained within acceptable guideline specifications.The following statistical effect concentrations were obtained after 72 hours of exposure based on growth rate: EC10 : 9.73 mg/L; EC50: 26.8 mg/L
