- Ecotoxicity
When evaluated as a group, the acrylate esters have similar ecotoxicity data.LC50 values in freshwater fish ranged from 1.81 and 5.2 mg/L, EC50 values in freshwater invertebrates (Daphnia magna) were between 1.3 and 8.74 mg/L, and EC50 values in freshwater algae were between 1.71 and 14.6 mg/L, respectively. Thus, effect values were all in the same range of concentrations with Daphnia magna as the most sensitive freshwater species by a narrow margin. A 21-day chronic life-cycle study with Daphnia magna is available with ethyl acrylate with a respective NOEC of 0.19 mg/L, and another with n-butyl acrylate with a NOEC of 0.136 mg/L. In addition, several NOEC values from studies in algal species are available ranging from 0.45 to 3.85 mg/L.

- Environmental Fate
In contact with water, tBA will hydrolyze slowly. Photodegradation in air will proceed slowly, too. tBA was not readily biodegradable in an OECD 310 -Screening test. After 28 days a biodegradation degree of 50 - 60 % was determined. The 10-day-window criterion for ready biodegradability was not fulfilled. Based on these data, tBA is considered to be partly or moderately biodegradable.; Degradation products expected for tBA are acrylic acid and tert-butanol. Acrylic acid is readily biodegradable according to OECD criteria. The biodegradability of tert-butanol was investigated in a CO2-Headspace test according to ISO 14593 (non-GLP). After 28 days a biodegradation degree of 70 - 80 % was reached. Tert-butanol was considered to be biodegradable. Taking all these data into consideration, tBA can be expected to be (inherently) biodegradable in the environment. Formation of persistent breakdown products is not expected.; Based on an experimental log Kow and calculated BCF, a potential for bioaccumulation is not to be expected. Adsorption of tBA to the solid soil phase is not expected. Fugacity model calculation (Mackay Level I) revealed the atmosphere as the main target compartment for distribution which is also indicated by the substance's physicochemical properties.
