【 摘 要 】

Analysis of the natural abundance ¹⁴C content of dibutyl phthalate (DBP) from two edible brown algae, Undaria pinnatifida and Laminaria japonica, and a green alga, Ulva sp., revealed that the DBP was naturally produced. The natural abundance ¹⁴C content of di-(2-ethylhexyl) phthalate (DEHP) obtained from the same algae was about 50–80% of the standard sample and the ¹⁴C content of the petrochemical (industrial) products of DBP and DEHP were below the detection limit.
