Additional information

Aquatic PNECs

Fish, Daphnia and algal acute toxicity endpoints are available. The lowest reported appropriate endpoint was a 72 hour algal ErC50 of 639 mg/L. The following PNECs were calcuated using this endpoint:

PNEC Aqua (freshwater) - Based on an assessment factor of 1000 the PNEC is 0.639 mg/L.

PNEC Aqua (marine water) - Based on an assessment factor of 10000 the PNEC is 0.0639 mg/L.

PNEC Aqua (intermittent releases) - Based on an assessment factor of 100 the PNEC is 6.39 mg/L.

STP PNEC

The lowest available endpoint is a NOEC of 1000 mg/L. Based on an assessment factor of 10 and an endpoint of 1000 mg/L the PNEC STP is 100 mg/L.

Soil PNEC

Three long-term toxicity studies are available on soil organisms and the lowest endpoint is a NOEC of 125 mg/kg dw. Based on an assessment factor of 10 the PNECsoil is 12.5 mg/kg dw.

Conclusion on classification

No classification is triggered based on available data, according to Directive 67/548/EEC or EC Regulation 1272/2008.
