Description of key information

The ECOSAR QSAR model predicts that 30-day, NOEC cited as a ChV value would to be 204.500 mg/L (ppm) for fresh water plants.
The ECOSAR QSAR model predicts that 96-hr EC50 value would to be 744.740 mg/L (ppm) for fresh water plants.

Key value for chemical safety assessment

EC50/LC50 for freshwater plants:
744.74 mg/L
EC50/LC50 for marine water plants:
74.5 mg/L
EC10, LC10 or NOEC for freshwater plants:
204.5 mg/L
EC10, LC10 or NOEC for marine water plants:
20.45 mg/L

Additional information

The available data for saltwater aquatic plants are limited and to obtaine the value for PNECs for saltwaters is taken account a assesment factor 10 to extrapolate to LC50 following the “Guidance on Information Requirement and Chemical Safety Assessment R.10: Characterisation of dose [concentration]- response for environment”and “Table R.10-5 Assessment factors proposed for deriving PNEC water for saltwater for different data sets”, to account for the possibility that greater taxonomic diversity in the marine environment makes it likely that some marine taxa may be more sensitive than the most sensitive freshwater taxa.
