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. %K brown alga %K green alga. %K 14C natural abundance %K dibutyl phthalate %K di-(2- ethylhexyl) phthalate %U http://www.mdpi.com/1660-3397/4/4/290
