A procedure is described for the determination of arsenic in soils at the parts per million level and water at the parts per billion level. Determinations are made by direct introduction of arsine gas into the flame of an atomic absorption spectrophotometer. An easily constructed apparatus is described for introducing arsine into the flame. Soils from various states, as well as water samples from Texas waterways, are studied for arsenic content. Recoveries of arsenic added to soils and water samples ranged from 93.0 to 106.0%.
