Additional information

For terrestrial ecotoxicology, 6 ecotoxicity studies were performed with Eisenia fetida, Folsomia candida, Lepidium sativum, Phaseolus vulgaris, Secale cereale and soil microbial activity. The lowest NOEC was observed for Folsomia candida.

 species NOEC  (g Cd Te/kg DW) reference 
Eisenia fetida 2.1 Vito (2012f)
Folsomia candida 0.01 Notox (2012b)
Lepidium sativum 2.1 Vito (2012g)
Phaseolus vulgaris 2.1 Vito (2012g)
Secale cereale 2.1 Vito (2012h)
Soil microbial activity 2.1 CEMS (2012)

A basic assumption made in this hazard assessment and throughout this CSR, (in accordance to the same assumption made in the EU RA process) is that the ecotoxicity of CdTe is due to the Cd++ion. As a consequence, terrestrial PNEC in this report are expressed as “cadmium”, not as Cd Te as such, because ionic cadmium is considered to be the causative factor for toxicity.
