Additional information

Aquatic PNECs

Data has been obtained from studies conducted using 2-Oxepanone, polymer with 1,4- butanediol.

The derived PNECs are presented below:

PNEC Aqua (freshwater) - Based on an assessment factor of 1000, the PNEC is 0.072 mg/L.

PNEC Aqua (marine water) - Based on an assessment factor of 10000 the PNEC is 0.0072 mg/L.

PNEC Aqua (intermittent releases) - Based on an assessment factor of 100 the PNEC is 0.72 mg/L.

PNEC STP- Based on an assessment factor of 1 the PNEC is 461 mg/l

No PNECs for other compartments (soil, air, sediment) are considered necessary.

Conclusion on classification

No classification is triggered based on available data, according to EEC Council Directive 79/831/EEC Annex VI, Part II (D) as described in Commission Directive 93/21/EEC or Regulation (EC) No 1272/2008. No hazards for the environment have been identified.
