Additional information

PNEC aqua:

The PNEC aqua was derived on the basis of the lowest actue toxicity test (LC50 or EC50) for all 3 trophic levels (fish, daphnia , algae) and applying an assessmentfactor of 1000. The PNEC aqua base on the test for acute toxicity in fish : PNEC aqua = 5.74 mg/l/ 1000 = 0.00574 mg/l

PNEC marine aqua: The PNEC marine aqua was derived on the basis of the lowest actue toxicity test (LC50 or EC50) for all 3 trophic levels (fish, daphnia , algae) and applying an assessmentfactor of 10000. The PNEC aqua base on the test for acute toxicity in fish : PNEC aqua = 5.74 mg/l/ 10000 = 0.000574 mg/l

PNEC aqua intermittent: The PNEC aqua intermittent was derived on the basis of the lowest actue toxicity test (LC50 or EC50) for all 3 trophic levels (fish, daphnia , algae) and applying an assessmentfactor of 100. The PNEC aqua intermittent base on the test for acute toxicity in fish : PNEC aqua = 5.74 mg/l/ 100 = 0.0574 mg/l

PNEC STP: The PNEC STP was derived on the basis of the actue toxicity test for aquatic microorganisms (OECD 209) and applying an assessmentfactor of 100. PNEC STP = EC50: >1000 mg/l/ 100 = 10 mg/l

PNEC sediment

The PNEC sediment was derived on the basis of the equillibrium partitioning method ( REACH: Technical guidance document for preparing the chemical safety asssessment: R10.6.3).

PNECsediment= (Ksusp-water/Rhosusp) x PNECwaterx 1000
	Ksusp-water	Rhosusp	PNECwater	PNECsediment

PNEC marine sediment

The PNEC marine sediment was derived on the basis of the equillibrium partitioning method ( REACH: Technical guidance document for preparing the chemical safety asssessment: R10.6.3).

PNEC soil

The PNEC soil was derived on the basis of the equillibrium partitioning method ( REACH: Technical guidance document for preparing the chemical safety asssessment: R10.7.1).

Conclusion on classification

Based on the acute aquatic toxicity data for the 3 trophic levels (fish, daphnia, algae), the test substance has to be considered as toxic for aquatic organisms. Based on the classification scheme considering aquatic toxicity (LC50: 5.74) and biodegradation (readily biodegradable ) the test substance is not classified.
