Abstract

When testing a new compound (Chlorfenvinphos) for killing ectoparasites on dogs, Vernon Brown of the Shell Toxicology Lab in England found the LD50 differences between species to be enormous. For rats, the LD50 value was 12 mg per kilogram of ordinary feed, for mice 100-200 mg, while dogs proved indestructible at 12,000 mg.
