Additional information
Derivation of PNECoral birds was made according to ECHA Guidance Document on information requirements and chemical safety assessment Chapter R.10. where:
NOECbird= NOAELbird*CONVbird
NOAELbird= 7mg/kg/d
CONVbird=8kgbw/d/kgfood
NOECbird=7*8=56 kg/kgfood (TOXoral)
PNECoral bird=TOXoral/AForal=56/90=0.62kg/kgfood
AForal= 90 (Tabela R.10-13 – test duration 90 days)
Conclusion on classification
In accordance with Regulation EC 1272/2008 (CLP) and based on available data substance can be classified as hazardous to the aquatic environment chronic category 2 as the substance is poorly biodegradableac and acute and long-term toxicity to fish, acute toxicity to Daphnia magna and acute toxicity to algae is 1 mg/L < LC50 < 10 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
