Additional information

A study to OECD 207 was performed to assess the acute toxicity of sodium bromide to the earthworm (Eisenia foetida) in an artificial soil. Earthworms were exposed to a range of concentrations of 10, 32, 100, 320 and 1000 mg bromide/kg of soil for a period of 14 days. The number of mortalities were determined after 7 and 14 days exposure. The No Observed Effect Concentration (NOEC) was 10 mg bromide/kg on the basis that no mortalities were observed after 14 days exposure and additionally no sub-lethal effects on weight or behaviour were observed at 10 mg bromide/kg.
