Additional information

Above demonstrated computations on the different PNECs all are based on the standard default factors given by ECHA's "Guidance on information requirements and chemical safety assessment Chapter R.10: Characterisation of dose [concentration]-response for environment" and "ECB - Technical Guidance on Risk Assessment, in support of Commission Directive 93/67/EEC on Risk Assessment for new notified substances, Commission Regulation (EC) No 1488/94 on Risk Assessment for existing substances, Directive 98/8/EC of the European Parliament and of the Council concerning the placing of biocidal products on the market, Part II".

Conclusion on classification

The most sensitive acute aquatic toxicity study was the study with algae, revealing an EC50 of 66.5 mg/L. In combination with the fact that substance registered is not rapidly degradable, the resulting CLP classification is “Hazardous to the aquatic environment (long-term) – Aquatic Chronic 3” and with Hazard statement “H412: Harmful to aquatic life with long lasting effects”. The corresponding DSD classification is “R52/53 Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment”.
