Description of key information

The lowest NOEC values of 258 and 433 mg/kg soil dw were put forward for the derivation of a terrestrial PNEC

Key value for chemical safety assessment

Long-term EC10, LC10 or NOEC for soil macroorganisms:
258 mg/kg soil dw

Additional information

Kuperman et al (2008) reported reliable NOEC-values for Ba (added as barium nitrate) for twodifferent soil macro-organisms (E. fetida, E. crypticus). The derived effect values were based on ecological relevant endpoints (mortality and reproduction). Reproduction was the most sensitive endpoint, and NOEC-values were 258 and 433 mg Ba/kg soil dw for E. fetida and E. crypticus, respectively.
