Additional information

The long-term toxicity of p-cresol to aquatic invertebrates was determined by a test according to the preliminary guideline proposal of the German Umweltbundesamt from1984. The 21d-NOEC is 1 mg/L for Daphnia magna.

In a non-guideline study with a 4 generations of the planarian Dugesia tigrina, an 80 d-EC10 of 2 mg/L was measured.
