ACUTE TOXICITY

Reliable acute toxicity data for freshwater organisms are available for three trophic levels: aquatic invertebrates, fish and algae:

Fish

The results indicate that Neo Heliopan® AP was not found to be toxic to zebrafish after 96 hours up to a nominal concentration of 100 mg/L and a geometric mean measured concentration of 90 mg/L.

Daphnia magna

The results indicate that Neo Heliopan® AP was not found to immobilise the daphnia magna up to a nominal concentration of 100 mg/L and a geometric mean measured concentration of 96.6 mg/L.

Algae

The results indicate that Neo Heliopan® AP was not found to inhibit the growth of the freshwater green algae Desmodesmus subspicatus up to a nominal concentration of 100 mg/L and a geometric mean measured concentration of 88.2 mg/L.

CHRONIC TOXICITY

Daphnia magna

At test concentrations of 0.316 and 0.1 mg test item/L, significant effects could not be observed.

The EC10 value is estimated at >1 mg/L (nominal for reproduction and immobilitsation effects) as a mean reproduction of 92.3 % was observed at the highest tested concentration of 1 mg/L. The No Observed Effect Concentration (NOEC) and the Lowest Observed Effect Concentration (LOEC) were as follows:

NOEC: 0.316 mg/L (nominal)

LOEC: 1 mg/L (nominal).

Toxicity to microorganisms

Neo Heliopan® AP does not inhibit respiration in activated sludge up at a concentration of 10000 mg/L. This concentration is considered an unbounded NOEC.
