Results with reference substance (positive control):
Not relevant
Reported statistics and error estimates:
No information provided in review

NOEC values of between 0.2 -7.5 mg/m3 HF are reported for plants.

Validity criteria fulfilled:
not applicable
Conclusions:
Calculated NOEC values are provided for categories of plant species.
Executive summary:

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 mg/m3 HF are reported for plants.

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 mg/m3 HF are reported for plant species (EU RAR, 2001).
