Additional information

The acute toxicity (LC50/EC50) of tetraammineplatinum(II) hydrogen carbonate to aquatic invertebrates (Daphnia magna) is 28 mg/L, equivalent to 14.18 mg Pt/L (Lebertz, 1997), while the acute toxicity of the related substance tetraammineplatinum(II) diacetate to aquatic species for the remaining trophic levels ranges from 52 mg/L to > 100 mg/L (24.4 mg Pt/L to >46.95 mg Pt/L) (Migchielsen, 2006a; 2006b).

 

For aquatic organisms, the lowest toxicological value of 14.18 mg Pt/L (28 mg/L, 48-hr EC50 for tetraammineplatinum(II) hydrogen carbonate in freshwater Daphnia magna) has been taken forward for PNEC derivation. The 30-min EC50 of 46.95 mg Pt/L (100 mg/L, activated sludge respiration test with tetraammineplatinum(II) diacetate) (Desmares-Koopmans, 2006) has been utilised for the derivation of a PNEC for microorganisms in sewage treatment plants.

 

The PNEC value for each environmental compartment has been derived on the basis of platinum metal.
