THE EFFECT OF ARSENICAL DIPPING ON THE ARSENIC CONTENT OF SHEEP TISSUES

Abstract
The arsenic residues in sheep tissues resulting from arsenical dipping which can be expected to be present at time of marketing have been established as being below one part per million.Large amounts of arsenic are shown to persist in the wool of treated sheep indicating extended and continuing protection against blowfly strikes. While several scourings remove most of the arsenic from wool, some is firmly held by the fibers even after repeated scourings.
