Description of key information

In this l4-days limit test the acute toxicity of Expandable Natural Graphite to the earthworm Eisenia fetida was assessed. No significant effects on mortality and biomass development were observed for the test item concentration at 1000 mg/ kg soil dry weight. Behind this background, the NOEC for both, mortality and biomass development is 1000 mg/kg soil dry weight. The LOEC is assumed to be above 1000 mg/kg soil dry weight.
