Arsenic excretion by monkeys dosed with arsenic-containing fish or with inorganic arsenic.

Four adult female Cynomolagus monkeys were given single oral dose of fish arsenic. 67% of the arsenic was excreted with the urine and 10% with the feces, essentially within 5 days post exposure. The same monkeys were later dosed with inorganic arsenic and 76% of it was excreted with the urine, and practically nil with the feces.
