Applicant's summary and conclusion

Conclusions:
Jiang & Singh (1994) found that application rates of arsenite and arsenate at ≥ 50 mg As(III) or As(V)/kg caused significant reductions in the yield of ryegrass (Lolium perenne) and barley (Hordeum vulgare).
Anastasia & Kender (1973) grew lowbush blueberry (Vaccinium angustifolium) in a loamy sand containing As2O3. Growth was significantly inhibited at ≤ 69.5 mg As/kg soil.
Woolson et al. (1971) grew corn seedlings for 4 weeks in Lakeland loamy soil, and growth was reduced by 50% at a concentration of 42 mg As/kg.
