Additional information

Conclusion on classification

Classification for environment is implemented according to the approach specified for metals outlined in the “Guidance on the Application of the CLP” (April, 2012).

Based on the solubility values obtained from the transformation/dissolution test and the respective Effect Reference Values (ERVs) for the metal the following classification for environmental hazards has to be assigned for elemental Tellurium:

 

Effect Reference Values (ERVs):

 

 

Tellurium

Values expressed as Te

Tellurium dioxide

Values expressed as Te

Transformation/dissolution test:

Screening test:

24 hours, loading 100 mg/L

pH 6

pH 8

 

Main test:

pH 8, equilibrium after 7 day:

Loading 1mg/L

Loading 10 mg/L

Loading 100 mg/L

 

 

 

761 µg/L

1,355 µg/L

 

 

 

28.1 µg/L

183.3 µg/L

1.76 mg/L

 

 

 

 

Short term toxicity to fish:

 

 

LC50 > 37.1 mg/L (measured)

Short term toxicity to aquatic invertebrates:

 

EC50 5.79 mg/L

(measured)

Short term toxicity to aquatic alga and cyanobacteria

 

EC50 > 11.71 mg/L

NOEC 3.33 mg/L

(measured)

 

Hazardous to the aquatic environment:

 

·       acute/short-term:        No classification required

·       long-term:                    Aquatic Chronic 4        

                                         H413:May cause long lasting harmful effects to aquatic life
