Description of key information

Sodium bromide: Terrestrial plant test, seedling emergence and growth test

Key value for chemical safety assessment

Short-term EC50 or LC50 for terrestrial plants:
1 000 mg/kg soil dw
Long-term EC10, LC10 or NOEC for terrestrial plants:
180 mg/kg soil dw

Additional information

A study to OECD No 208 was performed to assess the effects of sodium bromide on the emergence and growth of three plant species.

Three plant species were exposed to concentrations of 100, 180, 320, 560 and 1000 mg bromide/kg. The number of seedlings emerged and any mortalities and/or morphological abnormalities were determined daily for 21 days after 50% emergence in the control for each species.

The EC50 (emergence) and EC50 (growth) for the test material to the plants tested based on nominal test concentrations were greater than 1000 mg bromide/kg. The No Observed Effect Concentration for both emergence and growth was 1000 mg bromide/kg however, morphological effects were observed therefore the overall No Observed Effect Concentration was considered to be 180 mg bromide/kg to oat (Avena sativa).
