TYPE AND FREQUENCY OF MEASUREMENT AND OBSERVATIONS
- Water quality and light intensity measurements: pH-value, temperature and oxygen saturation were measured in all test vessels at the beginning and at the end of the exposure and every 24 hours. ln the control, total hardness of the water was determined at the beginning of the exposure. During exposure, the water temperature was recorded continuously ( once per hour) by a data Iogger. The light intensity on the surface of the test aquaria were measured at the start of the test.
- Observation intervals: Observations were made after 3, 24, 48, 72 and 96 h.
- Criteria of effects: Fish were considered dead if there was no visible movement (e.g. gill covers movement) and if tauehing of the caudal peduncle produced no reaction. Records were kept of visible abnormalities (e.g. loss of equilibrium, swimming behaviour, respiratory function, pigmentation, etc.).
- Measurement of fish size: At the start of the exposure, body weight and total length of a representative number of 7 test fish was determined . These fish were not used for testing.

Description of key information
The ecotoxicological potential to fish is assessed based on data available for 2-Propenoic acid, C12-14alkyl esters [84238-60-8], 2-Propenoic acid, C16-18-alkyl esters (CAS 90530-21-5), and 2-Propenoic acid, C18-22-alkyl esters (CAS 85085-17-2).

Conclusion
The absence of short-term toxic potential to fish was demonstrated by in vivo assays for 2-Propenoic acid, C12-14-alkyl esters (84238-60-8), 2-Propenoic acid, C16-18-alkyl esters (90530-21-5) and 2-Propenoic acid, C18-22-alkyl esters (85085-17-2). With regard to the observed LC50 [96 h] values of > 100 mg/L (WAF) it can be concluded that all members of the category are not toxic to fish.

Additional information
The test substance 2-Propenoic acid, C12-14-alkyl ester was tested in a 96 h acute toxicity study to golden orfe according to DIN 38412. The nominal concentrations were 0, 100, 215, 464 and 1000 mg/L. The observed symptoms were apathy, narcotic-like state, tumbling. The LC100 and the LC50 were 1000 mg/L and 460 mg/L, respectively. The NOEC-value and the LC0 were 215 mg/L and 215 mg/L (BASF 1988).
The acute lethal toxicity of 2-Propenoic acid, C16-18-alkyl esters (CAS 90530-21-5) to Danio rerio (Zebrafish) was investigated under static exposure conditions over a period of 96 h, using the Water Accomodated Fraction (WAF) approach. The singly applied loading rate was 100 mg/L. GC-FID analysis of the test substance was conducted in the definitive test at the beginning of the test and after 24, 48, 72 and 96 h of incubation. The test concentration was below the quantification limit of 0.02 mg/L throughout the test. Thus, evaluation was based on the loading rate. At the loading rate of 100 mg/L, none of a total of seven fish died after 96 h of exposure. No mortality was observed in the blank control. Toxic effects other than mortality, e.g. loss of coordination, hypo- or hyperactivity and swimming on the back, were not observed. The no-observed-effect concentration (NOEC) was 100 mg/L with respect to the loading rate. 100% mortality (LC100) could not be detected. Based on the binominal theory, the absence of mortality provides at least 99% confidence that the LC50 is greater than the applied loading rate of 100 mg/L (BASF SE, 2012).
The acute toxicity to fish (zebrafish), of the test substance and 2-Propenoic acid, C18-22-alkyl esters was determined according to OECD-Guideline for Testing of Chemicals No. 203 (1992) and EU Council Regulation No. 440/2008/ C.1 (2008). A static test was performed. A single water accommodated fraction (WAF) of 100 mg/L was prepared and tested. Per definition of the WAF, all terms related to concentration Ievels were given as loading Ievels because partly dissolved compounds and mixtures cannot be related to concentrations. The duration of the test was 96 hours. Seven test organisms each were exposed to the WAF and the control. Water quality parameters like pH-value, temperature and oxygen-saturation, measured after 0, 24, 48, 72 and 96 h, were determined to be within the acceptable Iimits. The concentration of the test item in the loading Ievel and the control were analytically verified via analysis of organic carbon (TOC, according to DIN EN 1484) at the start of the exposure. All effect Ievels are given based on the nominal loading of the test item. The NOEL was laid down as 100 mg/L. The LL50 after 96 hours was > 100 mg/L. All effect levels are given based on the nominal level of the test item. Therefore the test substance was found to cause no toxic effects to zebrafish after 96 hours when tested with a loading level of 100 mg/L (BASF SE, 2012).
