Persistence of cyanazine in the aquatic environment / Y.L. Lau, D.L.S. Liu and G.J. Pacepavicius. : En13-5/98-5E-PDF

"The persistence of cyanazine (2-[[4-chloro-6-(ethylamino)-1,3,5,-triazin-2-yl]-amino]-2-methylpropanenitile) in the aquatic environment was studied through experiments on volatility and uptake by bottom-attached biofilms. The results indicate that cyanazine can be considered non-volatile up to 35 °C. Cyanazine was lost from the water in the presence of algal or bacterial biofilms. All evidence points towards uptake by the biofilm as the cause of the disappearance of cyanazine. However, no degradation products were found showing that the cyanazine could not be biodegraded or biotransformed. Cyanazine formed bound residues within the biofilm which could not be extracted, thus increasing its persistence in the aquatic environment"--Abstract.
