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.
