Abstract
In order to study the distribution of phthalates (D. M. P., D. E. P., D. B. P., D. E. H. P.) Carbonyl-14C-phthalate was administrated orally to the rats, and mice;
The highest concentration of radioactirity in blood and tissue was observed at about 30min-1 hrs after administration and gradually decreased,
The relatively highest concentration of radioactivity was found in the kidney and liver; Radioactivity was rapidly excreted almost in the Urin and ratio of excretion in feces and urine, amounted to 4% and 90% (D. M. P.) 25% and 82% (D. E. P.) 20% and 41% (D. B. P.) 22% and 41% (D. E. H. P.) respectively within 144hr,
