Additional information

One key study is available for each of the following endpoints:

 

- Short-term toxicity to fish:

LC50 (96h) > 100 mg/L; LOEC (96h) > 100 mg/L; NOEC (96h) ≥ 100 mg/L (OECD guideline 203) (klimisch 1)

Based on the results of this study, sodium hypophosphite would be considered as non hazardous to fish (Brachydanio rerio) according to the CLP regulation (EC) n° 1272/2008.

 

- Short-term toxicity to aquatic invertebrates:

EC50 (48h) > 100 mg/L; EC0 (48h) ≥ 100 mg/L (OECD guideline 202) (klimisch 1)

According to the CLP regulation (EC) N° 1272/2008, in the tested conditions sodium hypophosphite is considered non-hazardous to daphnids (Daphnia magna).

 

- Toxicity to aquatic algae and cyanobacteria:

EC10, EC20 and EC50 (72h) for growth rate and yield >100 mg/L (OECD Guideline) (klimisch 1)

LOEC (72h) for growth rate and yield >100 mg/L (OECD Guideline 201) (klimisch 1)

NOEC (72h) for growth rate and yield ≥ 100 mg/L (OECD Guideline 201) (klimisch 1)

According to the CLP regulation (EC) N° 1272/2008, in the tested conditions sodium hypophosphite is considered non-hazardous to algae (Pseudokirchneriella subcapitata) for growth rate and yield.

 

- Toxicity to microorganisms:

EC50 (3h) > 1000 mg/L; EC10 (3h) ≥ 1000 mg/L (OECD guideline 209) (klimisch 1)

Based on the results of this study, sodium hypophosphite is not toxic to these microorganisms.
