Di-(2-ethylhexyl)-phthalate (DEHP) is a widely used plasticizer and ubiquitous environmental contaminant. The potential health hazards, including teratogenicity, from exposure to DEHP may be related to the role of DEHP or its metabolites in the trans-activation of peroxisome proliferator-activated receptors (PPARs).

Environmental fate and aquatic effects data were examined for a series of C4 (butyl acetate, 1-butanol, isobutyl alcohol) and C8 (2-ethylhexanol and 2-ethylhexanoic acid) oxo-process chemicals. Manufacturing of these chemicals requires enclosed equipment, so environmental releases are generally limited to

2-Ethylhexanoic acid (2-EHA), is an industrial chemical and a toxic biotransformation product of the plasticizer di(2-ethylhexyl)phthalate. Its immunological effects are unknown. 2-EHA resembles structurally C18 fatty acids, which are known activators of respiratory burst in human polymorphonuclear leukocytes (PMNL). Therefore
