The Ames assay was used to investigate the mutagenicity of several phthalate esters as an approximation of their carcinogenic potential. The ortho diesters, dimethyl phthalate (DMP) and diethyl phthalate (DEP) produced a positive dose-related mutagenic response with Salmonella TA100, but only in the absence of S-9 liver enzymes. Dibutyl, di(2-ethylhexyl), mono(2-ethylhexyl), and butyl benzyl ph...

The probability of nonoccupational exposure to phthalates is high given their use in a vast range of consumables, including personal care products (e.g., perfumes, lotions, cosmetics), paints, industrial plastics, and certain medical devices and pharmaceuticals. Phthalates are of high interest because of their potential for human exposure and because animal toxicity studies suggest that some ph...

BACKGROUND Diethyl phthalate (DEP) and di-n-butyl phthalate (DnBP) are industrial chemicals found in consumer products that may increase risk of adverse health effects. Although use of personal care/beauty products is known to contribute to phthalate exposure, no prior study has examined feminine hygiene products as a potential phthalate source. In this study, we evaluate whether vaginal douchi...

The temperature dependence of the micelle structures formed by poly(styrene-b-isoprene) (SI) diblock copolymers in the selective solvents diethyl phthalate (DEP) and tetradecane (C14), which are selective for the PS and PI blocks, respectively, have been investigated by small angle neutron scattering (SANS). Two nearly symmetric SI diblock copolymers, one with a perdeuterated PS block and the o...

Herein, a stable and S-scheme Fe3O4@CuCr-LDH nanocomposite was synthesized used for the photocatalytic degradation of diethyl phthalate (DEP) through activation peroxymonosulfate (PMS). In comparison with pure Fe3O4, LDH, demonstrated significantly enhanced activity due to its charge-carrier migration mechanism. The prepared composite also magnetically recoverable from treated water which is fa...
