NOEC (3h) = 1000 mg/L (OECD 209)

Key value for chemical safety assessment

Additional information

One study is available on the toxicity of 1,2-Benzenediol, -3,5dialkyl-, 1,2-dicarboxylate to microorganisms. The study was conducted according to OECD Guideline 209 and GLP (Schaefer and Twilley, 2012). Activated sludge from a waste water treatment facility, receiving wastes from predominantly domestic sources, was exposed to the test substance at nominal concentrations of 10, 100 and 1000 mg/L. No significant effect on the respiration rate was observed, and the NOEC and the EC50 were determined to be 1000 mg/L and > 1000 mg/L, respectively.
