TL;DR: In this paper, the authors used labeled plasticizers and radioactivity measurements in conjunction with weight loss, can give quantitative information on the amount of migrated plasticizer, and on amount of the liquid medium that diffuses into the polymer during the migration process.

TL;DR: Dibutyl phthalate was isolated and identified in beef heart muscle mitochondria and in much smaller amounts from the heart muscle of the rat, rabbit, and dog.
Abstract: Phthalic ester plasticizers are widely used and have become environmental contaminants. About I billion pounds were produced in 1972 alone, usually as plasticizers in polyvinyl chloride plastics (GRAHAM 1973). Dibutyl phthalate (DBP) also is used as an insect repellent and diethylhexyl phthalate (DEHP) as a pesticide (FARM CHEMICALS 1971). These latter compounds have been found in soil (OGNER AND SCHNITZER 1970) and in aquatic organisms and water (ANONYMOUS 1971, MAYER et al 1972, HITES 1973). NAZIR et al (1973) isolated and identified DEHP in beef heart muscle mitochondria and in much smaller amounts from the heart muscle of the rat, rabbit, and dog.

TL;DR: In this article, a method was developed for the identification and determination of single primary and certain mixed plasticisers in polyvinyl chloride sheetings, using tetrahydrofuran solutions.
