Additional information
The PNECs have been derived using the results from the acute, aquatic toxicity studies; acute freshwater aquatic toxicity was measured for fish, the Japanese Medaka, an invertebrate, the water flea Daphnia magna, and the green algae Pseudokirchneriella subcapitata.
The result used to derive the PNEC was the 48-h EC50 value obtained from the immobilisation study in Daphnia magna, the most sensitive organism of all the acute, aquatic toxicity studies.
PNECs were calculated in accordance with REACH guidance on information requirements and chemical safety assessment, Chapter R.10: Characterisation of dose [concentration]-response for environment.
Conclusion on classification
Three acute, aquatic toxicity studies have been conducted on the test material, an acute toxicity to Japanese Medaka study, 48-hour immobilisation test using Daphnia magna and an algal growth inhibition study. All studies are GLP guideline studies and are adequately reported and therefore have been assigned a reliability 1.
In accordance with Regulation 1272/ 2008, the substance meets the criteria as an acute aquatic hazard category 1 based on the results of an acute Daphnia study; for Daphnia, the 48-h EC50 was found to be 0.057 mg/L. Furthermore, the substance meets the criteria as a chronic aquatic hazard category 1 as the substance is not readily biodegradable, the BCF value was experimentally determined as 4410 and the Log Pow has been determined as 6.2
