Aquatic toxicity potential of substance FAT 40034/F was evaluated
in studies conducted on three trophic levels that include fish,
invertebrates and lemna. Studies conducted for evaluation of toxicity to
microorganisms are also available. The key values are as follows: In a
48 h acute fish toxicity test, the test substance FAT 40034was observed
to have 48 h LD50 to Rainbow trout >1000 mg/L. The 48 h EC50 value of
the test substance FAT 40034 to Daphnia magna was determined to be >100
mg/L. The NOEC value for 48 hours was determined to be 100 mg/L. In a
GLP-compliant OECD Guideline 221 study, Lemna gibba (Duckweed) exposed
to the test item FAT 40034 recorded: 7 day ErC50 based upon the frond
number is >100 mg/L. 7 day EyC50 based upon the frond numbers is >100
mg/L. 7 day ErC50 based upon the frond dry weight is >100 mg/L. 7 day
EyC50 based upon the frond dry weight is >100 mg/L. The NOEC was 0.64
mg/L and the LOEC was >100 mg /L. Therefore, it can be concluded that
there were no toxic effects at saturation. The IC50 value of the test
substance FAT 40034 to microorganisms is greater than 300 mg/L. The PNEC
for waste-water treatment is 3 mg/L based on the IC50 of >300 mg/L
obtained in the activated sludge respiration inhibition test and an
assessment factor of 100. No long-term studies on aquatic organisms are
available and thus, PNECs for aqueous environment were derived by the
assessment method based on acute aquatic toxicity data. PNECs for
sediment and soil were derived by applying the partitioning method. The
substance has a low potential for bioaccumulation and its hazards for
predators via the food chain are not anticipated.
The substance was tested for all three
trophic levels in the aquatic environment using acute test design and
the lowest effect concentration is found to be EC/LC 50 >100 mg/L.
The substance is considered
non-biodegradable and hence will be not-classified for aquatic toxicity
hazards according to CLP.
