Description of key information

The toxicity to freshwater green algae was tested according to OECD 201 compliant with GLP. Due to the nature of Step 2 catalyst (UVCB), according to OECD 23 water accommodated fractions (WAF) were prepared.

Results:

NOELR (Pseudokirchneriella subcapitata; 72 h; static; growth rate) = 3.2 mg/L;

EL10 (Pseudokirchneriella subcapitata; 72 h; static; growth rate) = 5.9 mg/L (95% CI: 5.3-6.6)

EL50 (Pseudokirchneriella subcapitata; 72 h; static; growth rate) = 12.4 mg/L (95% CI: 11.8-13.2)

The acute toxicity to freshwater fish was tested according to OECD 203 compliant with GLP. Due to the nature of Step 2 catalyst (UVCB), according to OECD 23 water accommodated fractions (WAF) were prepared.

Result:

LL0 (Cyprinus carpio; 96 h; static) = 100 mg/L;

LL10 (Cyprinus carpio; 96 h; static) > 100 mg/L

LL50 (Cyprinus carpio; 96 h; static) > 100 mg/L

The acute toxicity to aquatic invertebrates was tested according to OECD 202 compliant with GLP. Due to the nature of Step 2 catalyst (UVCB), according to OECD 23 water accommodated fractions (WAF) were prepared.

Result:

EL0 (Daphnia magna; 48 h; static) = 100 mg/L;

EL10 (Daphnia magna; 48 h; static) > 100 mg/L

EL50 (Daphnia magna; 48 h; static) > 100 mg/L
