BACKGROUND Lab studies have suggested that ubiquitous phthalate exposures are related to obesity, but relevant epidemiological studies are scarce, especially for children. OBJECTIVE To investigate the association of phthalate exposures with body mass index (BMI) and waist circumference (WC) in Chinese school children. METHODS A cross-sectional study was conducted in three primary and three ...

BACKGROUND Widespread human exposure to phthalates, some of which are developmental and reproductive toxicants in experimental animals, raises concerns about potential human health risks. Underappreciated sources of exposure include phthalates in the polymers coating some oral medications. OBJECTIVE The objective of this study was to evaluate whether users of phthalate-containing medications ...

Phthalate esters (PEs), especially di-n-butyl phthalate (DBP) and di-(2-ethylhexyl) phthalate (DEHP) were detected in various water samples such as river water, well water and tap water. On degradation tests of PEs, Tempaku River water degraded almost 100% of diethyl phthalate (DEP), di-isobutyl phthalate and DBP, and approximately 70% of DEHP. All eight isolates from Tempaku River water (R1-R7...

OBJECTIVE Phthalates are ubiquitous industrial high-volume chemicals known as ligands to peroxisome proliferator-activated receptors (PPARs). Because PPAR-γ agonists modulate insulin sensitivity and are used to treat type 2 diabetes, we investigated whether circulating levels of phthalate metabolites are related to prevalent type 2 diabetes. RESEARCH DESIGN AND METHODS A total of 1,016 subjec...

Dibutyl phthalate (DBP) is a phthalic acid ester and is widely used in polymeric products to make them more flexible. DBP is found in almost every plastic material and is believed to be persistent in the environment. Various analytical methods have been used to measure DBP in different matrices. Considering the ubiquitous nature of DBP, the most important challenge in DBP analyses is the contam...

Experimental vapor pressures, vaporization, fusion and sublimation enthalpies of a number of dialkyl benzenedicarboxylates have been examined by correlation gas chromatography (CGC) experiments in order to identify a series of experimental measurements that appear to be internally self-consistent. The compounds studied in this regard include dimethyl phthalate dimethyl terephthalate, dimethyl i...

Plasticiser loss, a fundamental mechanism in the degradation of polymeric materials, leads to material instability and contamination environment. The process depends on environmental conditions, but size container which an object is housed thickness also play key roles rate plasticiser loss time at equilibrium reached. Understanding these dependencies provides valuable insight into plastic muse...

A Gram-negative strain (TJ) capable of growing aerobically on mixed phthalate esters (PAEs) as the sole carbon and energy source was isolated from the Haihe estuary, Tianjin, China. It was identified as belonging to the Sphingobium genus on the basis of morphological and physiological characteristics and 16S rRNA and gyrb gene sequencing. The batch tests for biodegradation of di-n-butyl phthala...

BACKGROUND In animal studies, some ortho-phthalates, including di(2-ethylhexyl) phthalate (DEHP) and di-n-butyl phthalate (DBP), have been shown to be reproductive and developmental toxicants. Human studies show widespread population exposure to background levels of phthalates. Limited evidence suggests that particularly high exposure levels may result from orally ingested medicinal products co...
