The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

There are no reliable experimental data on bioaccumulation for p-cresol available. Therefore, data of the isomer m-cresol and o-cresol are taken into account to describe the potential for bioaccumulation of p-cresol based on a read-across approach. The lowest value of 10.7 is used for assessment.

Bioconcentration factors (BCF) in fish (Leuciscus idus melanotus) were determined with 14C-labelled m-cresol. The fish were exposed to a 0.05 mg/l solution of the tests compound. After the test period of 3 days radioactivity was measured in water medium and fish. BCF values of 20 were obtained. In a flow-through test according to OECD guideline 305 E for o-cresol a BCF of 10.7 in zebrafish (Brachydanio rerio) were obtained.

Based on the results it is considered that p-cresol has no potential for bioaccumulation.
