Conclusion on classification

The substance is not classified for the environment.

Radia 7838 was tested to three trophic levels in fresh-water organisms to assess acute toxicity and was non-toxic below the water solubility (<1mg/L). In addition, the chronic toxicity data produced (using nominal concentrations above water solubility) from the algae study showed EC50 and NOEC data >1mg/L. Therefore, the substance need not be classified for acute hazard or long-term hazard categories Chronic 1, 2, or 3. Substances which are non-toxic up to their level of solubility can be classified as Chronic 4, however, since the substance is rapidly biodegradable, no classification is necessary.
