Additional information

The EU RAR reports NOEC values from 106 to 3000 mg/kg fluoride. The 63 day experiments were carried out in a micro-ecosystem containing poplar litter (30% o.m) and the isopod Porcellio scaber. Nitrification was found to be the most sensitive endpoint investigated in the micro-ecosystem test.
