Abstract
ABSTRACT TWO modules of stripper-harvested cotton, one that had been defoliated and then desiccated with arsenic acid (H3 As O4) and one that had been defoliated only, were subjected to 0 to 6 stages of lint cleaning. Standard methods were used to determine the amount of elemental arsenic (As) in samples of cottonseed, lint cleaner exhaust dust, gin room dust and lint from 0, 2, 4, and 6 stages of lint cleaning. The As content of the ginned lint and the dust samples from cotton desiccated with arsenic acid decreased as the number of lint cleaners used was increased. Only trace amounts of As were found in lint and dust from cotton not desiccated with arsenic acid.
