Description of key information

A short-term toxicity test with the golden orfe (Leuciscus idus melanotus) exposed to methacrylic acid, monoester with propane-1,2-diol and conducted under GLPs, under static conditions and following national standard test methods (DIN 38412 Teil 15; Teil 1) and resulted in a 48-hour LC50 value of 493 mg/L.

Key value for chemical safety assessment

Additional information

One acute freshwater fish study was available for methacrylic acid, monoester with propane-1,2-diol and considered reliable for assessment of this endpoint. The study was conducted with the golden orfe (Leuciscus idus melanotus) and was found to be of acceptable quality and assigned a Klimisch score of two. The study was conducted under static conditions, under GLPs and following national standard test methods. Though the exposure was conducted for 48 hours instead of the standard 96-hour exposure, the results from this study was sufficient to assess the toxicity of the substance to fish and determine that fish was not the most sensitive trophic level. The study concluded that the 48-hour LC50 value was 493 mg/L and was considered the key parameter for this endpoint.
