SUMMARY

Sulfuryl fluoride is used as an alternative to methyl bromide and is approved for use within the EU subject to national regulation. It is highly soluble in water and most organic solvents. It is extremely volatile. It is moderately toxic to humans and there are concerns that it may be a reproduction/fertility toxicant. It is modertaely toxic to honey bees, aquatic fauna and flora.
