Description of key information

Prolonged atmospheric exposure to fluoride in gaseous and/or particulate form can cause phytotoxicity in sensitive plant species.  A detailed field study of conifers growing at sites subject to atmospheric fluoride pollution found visible damage after exposure at a mean concentration of approximately 0.9 microgrammes fluoride/cu.m

Key value for chemical safety assessment

Additional information

In conifers, prolonged exposure to a fluoride concentration of 0.9 microgrammes fluoride/cu.m appeared sufficient to cause visible damage (seen as defoliation and/or pine needle necrosis/chlorosis).

Given the natural background level of fluoride present in soil (e.g. 200-700 mg/kg, reported for various soil types: HF - EU RAR, 2001), no trace quantity addition from LiPF6 use is likely to adversely affect higher plant growth.
