In accordance with section 3 of Annex XI of legislation EC1907/2006, the study does not need to be conducted. The use of butyl acrylate as a monomer, almost exclusively in closed systems for the production of polymers, indicates that environmental exposure would be limited. The volatility of n-butyl acrylate provides for volatilization of any releases to the air. Butyl acrylate is slowly photodegradable and readily biodegradable, and accidental releases to the environment would not result in accumulation or persistence. The relatively high water solubility and corresponding low log Kow indicate that no bioaccumulation potential exists.In order to assess long-term toxicity towards aquatic organisms, a 21-day chronic life-cycle study with Daphnia magna was conducted by BASF SE (2009).
Acute effects levels were in the same range of concentrations for all three trophic levels, i.e. between 1 and 10 mg/L. In order to assess long-term toxicity towards aquatic organisms, a 21-day chronic life-cycle study with Daphnia magna was conducted by BASF SE (2009).
