Additional information
At pH values relevant for the environment, (pH 4 -9), Bis(pentane-2,4-dionato-O,O')calcium is largely dissociated to pentane-2,4-dione (99.9% to 12.2%), and calcium is a natural constituent of the environment and is not considered relevant for hazard assessment. Thus, data from pentane-2,4-dione are used and converted to equivalent values for Bis(pentane-2,4-dionato-O,O')calcium using the molecular weights.
Existing data on pentane-2,4-dione (CAS 123 -54.6)
acute algae: 72 hr ErC50 = 83.22 mg/L
acute Daphnia: 48 hr EC50 = 25.9 mg/L
acute fish: 96 hr LC50 = 104 mg/L
chronic algae: 72 hr NOEC = 3.2 mg/L
chronic Daphnia: 21 days NOEC = 18 mg/L
Molecular weight correction (factor of 2.38)
Molecular weight (pentane-2,4-dione): 100.13
Molecular weight (Bis(pentane-2,4-dionato-O,O')calcium): 238.30
Adjusted data based on molecular weight corrections
acute algae: 72 hr ErC50 = 198.06 mg/L
acute Daphnia: 48 hr EC50 = 61.64 mg/L
acute fish: 96 hr LC50 = 247.52 mg/L
chronic algae: 72 hr NOEC = 7.62 mg/L
chronic Daphnia: 21 days NOEC = 42,8 mg/L
Conclusion on classification
Classification according to CLP (Regulation (EC) No 1272/2008).
Acute classification
All effect values are > 1 mg/L, thus Bis(pentane-2,4-dionato-O,O')calcium has no acute classification
Chronic classification.
The existing chronic data is for algae and Daphnia; chronic classification is done using both chronic and acute data and the most stringent outcome is then used for classification
Chronic data:
Substance is readily biodegradable and the existing chronic data (chronic algae: 72 hr NOEC = 7.62 mg/L; chronic Daphnia magna: 21 days NOEC = 42.8 mg/L). Using the criteria in Table 4.1.0(b)(ii) results in no classification
Acute data:
Substance is readily biodegradable and the lowest acute value (48 hr EC50 Daphnia: 61.64 mg/L). Using the criteria in Table 4.1.0(b)(iii) results in no classification
Final classification
Based on the existing data,Bis(pentane-2,4-dionato-O,O')calcium is not classified for the environment.
