Description of key information

A number of fumigation studies are reported in the EU RAR.

Key value for chemical safety assessment

Additional information

On the basis of a large number of fumigation experiments with plants (ornamental crops, fruit crops and conifers) exposed to HF, a relationship was derived between the NOEC and exposure time (all plant species). NOEC values were calculated for highly sensitive, sensitive and slightly sensitive plant species. NOEC values of between 0.2 -7.5 µg F/m3 are reported for plant species (EU RAR, 2001).
