Description of key information

The key study is a GLP-conform study by Egeler et al. (2010; Klimisch 1) on the effect of NaVO3 on the activated sludge respiration inhibition, according to OECD 209 guideline. The EC10 and EC20 values are 4500 and 29900 µg V/L, respectively. The EC50 value is > 100000 µg V/L as inhibition was less than 30% at the largest concentration tested. All results are based on total dissolved V concentrations.

Key value for chemical safety assessment

EC10, LC10 or NOEC for microorganisms:
4 500 µg/L
