Description of key information

The freshwater endpoint represents the lowest toxicity value obtained for Daphnia magna (Kuhn et al., 1988, 1989).
The marine endpoint represents the lowest toxicity value obtained for Trongylocentrotus droebachiensis [sea urchin] (Falk-Petersen et al., 1985).
Both endpoints were derived for p-Cresol

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
4.9 mg/L

Marine water invertebrates

Marine water invertebrates
Effect concentration:
5 mg/L

Additional information

Endpoints derived for p-Cresol have been used for this mixed xylenol assessment. Since there are structural and physical chemical similarities between the cresols and the other molecules within the mixed xylenol grouping it is acceptable to assume that their ecotoxicological profiles would be similar.
