Arsenic could be detected in the main organs and tissues of rats after administration of a single dose. The arsenic was most accumulated in the spleen, hair, lung and suprarenal gland organs, and kidney, heart, liver, bladder and skin came next.

After 15 continuous days of administration, arsenic contents in kidney and bladder tissues increased appreciably besides suprarenal gland, lung, hair and spleen.
