Di-n-octyl phthalate (DOP) is the straight chain isomer of di(2-ethylhexyl) phthalate (DEHP) which is a widely used plasticizer and an environmental contaminant. DEHP is a strong inducer of peroxisome proliferation in rat liver. This is significant since other compounds which

The oral administration of di-n-octyl phthalate (DNOP), mono-n-octyl phthalate (MNOP), di-(2-ethylhexyl) phthalate (DEHP) and clofibrate to young male Sprague-Dawley rats for 14 days resulted in liver enlargement. Morphological examination of liver sections from DEHP and clofibrate treated rats, but not

Two bacterial strains were isolated from activated sludge using mixtures of phthalic acid esters (PAEs) as the sole source of carbon and energy. One of the isolates was identified as Gordonia sp. strain JDC-2 and the other as Arthrobacter sp.
Manori J Silva et al.
Toxicology, 210(2-3), 123-133 (2005-04-21)
Di-n-octyl phthalate (DnOP) is a plasticizer used in polyvinyl chloride plastics, cellulose esters, and polystyrene resins. The metabolism of DnOP results in the hydrolysis of one ester linkage to produce mono-n-octyl phthalate (MnOP), which subsequently metabolizes to form oxidative metabolites.
R H Hinton et al.
Human toxicology, 4(3), 261-271 (1985-05-01)
Treatment of rats with hypolipidaemic drugs or with the plasticizer di-2-ethyl hexyl phthalate caused significant alterations in the concentration of certain plasma proteins. Certain proteins showed dose-dependent increases, in other cases the plasma concentrations fell in treated animals. The changes
