The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information


AQUATIC TOXICITY :

A full set of Acute toxicity studies are available for three trophic levels of freshwater species for FLORHYDRAL - Algae, Daphnia and Fish. The key Acute end-points are :

Algae 72 hour ErC50 = 11 mg/L

Daphnia 48 hour EC50 = 2.26 mg/L

Fish 96 hour LC50 = 4.6 mg/L


Chronic end-points available for FLORHYDRAL are :

Algae 72 hour ErC10 = 6.4 mg/L

Daphnia Reproduction 21-day NOEC = 0.71 mg/L


Additionally, full base-set aqautox studies are available for Florhydral-Acid (GR-81-6079) and Florhydral-Alcohol (GR-82-4332). Florhydral-Acid is the most relevant transformation product of FLORHYDRAL (via direct oxidation of the aldehyde group). The end-points determined are, as follows :


Florhydral-Acid (GR-81-6079) :

Algae 72 hour ErC50 > 90.6 mg/L

Algae 72 hour ErC10 = 54.7 mg/L

Daphnia 48 hour EC50 = 47.6 mg/L

Fish 96 hour LC50 = 20.8 mg/L


Florhydral-Alcohol (GR-82-4332) :

Algae 72 hour ErC50 = 16.8 mg/L

Algae 72 hour ErC10 = 6.69 mg/L

Daphnia 48 hour EC50 = 12.2 mg/L

Fish 96 hour LC50 = 5.81 mg/L


Thus, in the natural environment, FLORHYDRAL is rapidly transformed in to metabolites of lower toxicity than the Parent. The Alcohol will be transformed to the Acid, which is significantly less toxic (5- to 20-times less) than the Parent.
