Additional information
In accordance with the “Guidance on information requirements and chemical safety assessment, Chapter R.10" :
- an AF of 100 is applied to the long-term toxicity value NOEC(160.5 mg/L) for the derivation of the freshwater PNECaqua.
- an AF of 1000 is applied to the long-term toxicity value NOEC (160.5 mg/L) for the derivation of the marine water PNECaqua.
- an AF of 100 is applied to the lowest short-term toxicity value LC50 (548 mg/L) for the derivation of the intermitent release PNECaqua.
Conclusion on classification
- Fish are less sensitive compared to aquatic invertebrates based on the acute toxicity data.
- The lowest LC50 for fish is 2119.5 mg of MgCl2/L (541 mg Mg/L), which is more than 500 times higher than the chronic threshold concentration level (1 mg/L). This observation strongly suggests that no chronic effects below 1 mg Mg/L are expected for fish.
- No significant chronic effects are noted for both algae and daphnids at a concentration of 1 mg Mg/L
For the classification:
Acute:
lowest EC 50 for MgCL2: 548 mg/L, Biesinger et al.(1972)). The MgCL2 is not classified for acute toxicity.
Chronic.
lowest NOEC 21 d for MgCL2= 160.5 mg/L. The MgCL2 is not classified for chronic toxicity.
Although no chronic data are available for fish, the remaining Chronic 4 classification category under CLP can be removed based on the following arguments:
Magnesium Chloride is not classified as dangerous for the environment under the CLP regulation 1272/2008.
