Additional information

Three studies are presented for acute toxicity to Daphnia Magna, with the following results:

EC50 (48- h): 146 µg/L test mat. (estimated) based on: mortality (and mobility) 

LC50 (48- h): 0.27 mg/L test mat. (nominal) based on: mortality

LC50 (48- h): 0.09 mg/L test mat. (nominal) based on: mortality

 

The results clearly demonstrate that toxicity is prevalent. As it is known that the phosphates as a group demonstrate toxicity to aquatic organisms, the LC50 value for hazard assessment is taken as146 µg/L. The risk phrase "Very toxic to aquatic organisms" is applicable.
