Duration:
96 h
Dose descriptor:
EC50
Effect conc.:
> 100 mg/L
Nominal / measured:
nominal
Conc. based on:
other: water-accommodated fraction (WAF)
Basis for effect:

Validity criteria fulfilled:
yes
Conclusions:
Available data from 1-Octadecanol, phosphate, potassium salt were used to evaluate the acute toxicity on fish for Phosphoric acid, C12-18-alkyl esters, potassium salts.
In a 96-h acute toxicity study, Danio rerio were exposed to the read-across substance 1-Octadecanol, phosphate, potassium salt at concentrations of 0 and 100.0 mg/L nominal (WAF of 100 mg/L) under static conditions.
 
The 96h-LC50 was determined to be > 100 mg/L  (WAF based on nominal concentration).
The 96h-NOEC was determined to be ≥ 100 mg/L  (WAF based on nominal concentration).

Description of key information

The 96h-LC50 to fish (Danio rerio) for Phosphoric acid, C12-18 alkyl esters, potassium salts was determined to be > 100 mg/L (WAF based on nominal concentration) based on read-across information.

Key value for chemical safety assessment

Additional information

Available data from 1-Octadecanol, phosphate, potassium salt were used to evaluate the acute toxicity on fish for Phosphoric acid, C12-18-alkyl esters, potassium salts.

In a 96-h acute toxicity study, Danio rerio were exposed to the read-across substance 1-Octadecanol, phosphate, potassium salt at concentrations of 0 and 100.0 mg/L nominal (WAF of 100 mg/L) under static conditions.

 

The 96h-LC50 was determined to be > 100 mg/L  (WAF based on nominal concentration).

The 96h-NOEC was determined to be ≥ 100 mg/L  (WAF based on nominal concentration).
