Description of key information
In a study according to OECD TG 217 with the structural analogue methyl acrylate, the EC50 was found to be greater than the highest concentration tested.
EC50 > 1000 mg/kg soil dw (Sandy loam soil, OECD TG 217)
Key value for chemical safety assessment
Additional information
No experimental data on ethyl acrylate are available. Data on the structural analogue methyl acrylate are included.
A study was conducted according to OECD TG 217 in order to determine the effects of a range of concentrations of methyl acrylate on the respiration of the soil micro-flora and establish the concentration which was toxic to the micro-flora. One soil type, a sandy loam soil (Lufa type 2.3), was used. The test material dissolved in water was mixed in bulk with the soil to give a range of concentrations: 63, 125, 250, 500, and 1000 mg/kg dry mass soil. The glucose-induced respiration rates in treated and control soil samples were determined at day 0, 7 , and 28. The EC50 was found to be greater than the highest concentration of 1000 mg/kg dry mass.
