BACKGROUND In May 2011, a major incident involving phthalates-contaminated foodstuffs occurred in Taiwan. Di-(2-ethylhexyl) phthalate (DEHP) was added to foodstuffs, mainly juice, jelly, tea, sports drink, and dietary supplements. Concerns arose that normal pubertal development, especially reproductive hormone regulation in children, could be disrupted by DEHP exposure. OBJECTIVE To investiga...

In this work, an efficient cage-core peroxymonosulfate (PMS) catalyst was synthesized by applying electrospinning–calcination process to the cobalt–zeolitic imidazole framework (ZIF-67) crystals for catalytic degradation of dimethyl phthalate (DMP). The morphology and surface properties materials (ZIF-67, Z600 ZP400/600/800) were well characterized. ZP600 showed great performance DMP in initial...

A novel approach for production of polyetherimide (PEI) microparticles by liquid–liquid phase separation (LLPS) and precipitation is demonstrated the effect used solvents acetophenone dimethyl phthalate on obtained powders outlined. Interestingly, method allows one to produce semi-crystalline particles, while PEI known be hard crystallize typically in amorphous form. To get a deeper understandi...

The Harvard community has made this article openly available. Please share how this access benefits you. Your story matters. Phthalates are a class of chemicals used in the manufacturing of a variety of products (Crinnion 2010; Hauser and Calafat 2005; Romero-Franco et al. 2011). These chemicals are often used as plasticizers or solvents in food packaging, cosmetics, perfumes, nail polishes, fl...

BACKGROUND The ubiquitous use of phthalate esters in plastics, personal care products and food packaging materials results in widespread general population exposure. In this report, we extend our preliminary study on the relationship between urinary concentrations of phthalate metabolites and sperm DNA damage among a larger sample of men and include measurements of mono-(2-ethyl-5-hydroxyhexyl)...

BACKGROUND Phthalate diesters are commonly used and have been well established as environmental endocrine disruptors. However, few studies have examined their effects on sex steroid hormones in children. We followed children over time to examine the association between pre- and post-natal phthalate exposure and sex steroid hormone levels at 2, 5, 8, and 11 years of age. METHODS We recruited 4...
