Phthalates are a group of industrial chemicals with many commercial uses, such as solvents, additives, and plasticizers. For example, di-(2-ethylhexyl) phthalate (DEHP) is added in varying amounts to certain plastics, such as polyvinyl chloride, to increase their flexibility. In humans, phthalates are metabolized to their respective monoesters, conjugated,(More)
Metabolism of most diesters of phthalic acid in humans occurs by an initial phase I biotransformation in which phthalate monoesters are formed, followed by a phase II biotransformation in which phthalate monoesters react with glucuronic acid to form their respective glucuronide conjugates. The phase II conjugation increases water solubility and facilitates(More)
Exposure to di-(2-ethylhexyl) phthalate (DEHP) is prevalent based on the measurement of its hydrolytic metabolite mono-(2-ethylhexyl) phthalate (MEHP) in the urine of 78% of the general U.S. population studied in the 1999-2000 National Health and Nutrition Examination Survey (NHANES). However, despite the high level of production and use of DEHP, the(More)
