The toxicity of the cotton desiccant arsenic acid was studied in rabbits, guinea pigs, rats, and mice. The LDgg in mg/kg on oral administration is: for guinea pigs, 36; rabbits, 46; rats, 406.6; and for mice, 105.7. The most dangerous route of administration is intratracheal. The toxicity of arsenic acid is close to that of demeton or octamethyl pyrophosphoramide. Arsenic acid acts on the central nervous system and has cumulative properties. Broad use of arsenic acid in cotton growing can lead to considerable contamination of the soil and of open reservoirs. It is concluded that arsenic acid should not be used in cotton growing.
