Additional information

An experimental study was available and performed in compliance with GLP according to a Chinese standard test guideline. It has to be noticed that an important decrease of pH was observed in this study when the concentration of 2-methylglutaric acid increased. Therefore, it cannot be ruled out that the observed effects could result from an indirect impact of pH rather than from ‘true’ toxicity of the test substance. Furthermore, the results are expressed in mg/L and not in mg/kg of soil as classically required for a study dealing with terrestrial ecotoxicity. For these reasons, this study was scored as Klimisch 3. Under REACH, such study is not required because 2-methylglutaric acid (i) is not intentionally applied to soil, (ii) has a low volatility potential from water and because (iii) there is no indication for high adsorption (Log Kow < 5, Log Koc < 4), high persistence (rapidly degradable) or acute toxicity to aquatic organisms (L/EC50 > 100 mg/L in the three torphic levels). The study was nevertheless provided here because it was performed for the purpose of another regulation, a Chinese notification, which required the performance of this test in a Chinese laboratory.
