Additional information
Aquatic toxicity potential of substance FAT 40147 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 presented below:
The 96 hours LC50 value for zebra fish was determined to be 620 mg/L.
The 48 hours EC50 to Daphnia was determined to be >100 mg/L.
The 7-days EC50 to Lemna minor was determined to be >100 mg/L
The 21 days IC50 for bacterial toxicity of FAT 40147 was determined to be >300 mg/L.
Hence, based on the available data the test substance FAT 40147 can be considered as not toxic to aquatic species.
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.
Conclusion on classification
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.
