A recent food safety concern has arisen from the unapproved use of certain phthalates in a broad range of food/nutraceutical ingredients from Taiwan [53]. Consequently, phthalates are found in human residential and occupational environments in high concentrations, both in air and in dust. Phthalic acid esters (PAEs) are the most commonly used plasticizers which are added to provide desired flexibility and clarity to the polyvinyl chloride (PVC) plastics used in packaging, storage and delivery of food, drugs and cosmetics. China. [Article in Chinese] Wang KR(1), Cui MM(2), Shi YX(2). Cyclic organosilicon esters of ortho-phthalic acids, Chemistry of Heterocyclic Compounds, 10.1007/s10593-019-02592-5, (2019). Liao C(1), Yang P, Xie Z, Zhao Y, Cheng X, Zhang Y, Ren Z, Guo Z, Liao J. Epub 2019 Oct 13. As China is one of the largest consumers of phthalic acid esters, some human activities may lead to the accumulation of phthalic acid esters in soil and result in contamination. Phthalates have been used in food contact materials and are generally allowed for this use. Urban sprawl worldwide warrants the use of large quantities of industrial and household products containing phthalic acid esters (PAEs) resulting in adverse impacts on the quality of aquatic life in urban watercourses. Author information: (1)Sichuan Environmental Monitoring Centre, Chengdu, Sichuan, 610041, P.R. Phthalic acid (PA) is the final metabolite of phthalic acid esters (PAEs).

Compound Phthalic acid, dipropyl ester with free spectra: 3 NMR, 3 FTIR, and 3 MS. The aim of the study was monitoring of phthalic acid esters in agricultural soils of the Czech Republic over the period of 6 years, namely dibutyl phthalate (DBP) and di-2-ethylhexyl phthalate (DEHP). PAEs are ubiquitous in different environments and our daily life due to their large and widespread application. Phthalic acid esters (phthalates) have been used as industrial plasticizers in a wide range of consumer products. A wide variety of phthalic acid ester options are available to you, such as grade standard, usage, and type. Phthalic acid esters (PAEs), a class of organic pollutants with potent endocrine-disrupting properties, are widely present in municipal sludge. 178, Issue 4056, pp. Effects of phthalic acid esters on fetal health. Analysis of phthalic acid esters in sea water and sea sand using polymer-coated magnetic nanoparticles as extraction sorbent J Chromatogr A. SCHEMBL1681510. Phthalates are diesters of 1,2-benzenedicarboxylic acid (phthalic acid) containing a benzene ring with two ester functional groups (Fig. Crossref Sergey V. Basenko, Anastasiya S. Soldatenko, Silacyclophanones – cyclic organosilicon esters of isophthalic acid, Chemistry of Heterocyclic Compounds, 10.1007/s10593-018-2239-5, 54 , 1, (100-102), (2018). PAEs in all topsoil samples analyzed were detected, indicating that PAEs were ubiquitously environmental contaminants. Phthalic acid esters (PAE) are widely used during chemical synthesis and do not form covalent linkages with products. Phthalic acid esters have been used as plasticizers in numerous products and classified as endocrine-disrupting compounds.

These mammalian pancreatic CEases have been found to be nonspecific for degradation in relation to the diversity of the alkyl side chains of PAEs. Phthalic Acid Esters: Biological Impact Uncertain. 44.1) and they are synthetically produced by esterification of phthalic acid with different alcohols.Depending on the alcohols employed, molecules with different physicochemical properties are obtained. Bridgest Theeffects, overperiods from3 daysto9 monthsofadministration, ofdiets containingdi-2-ethylhexyl . Di-(2-ethylhexyl) phthalate was the major phthalic acid ester in the Mississippi River estuary, with mean levels of 0.1 μg/g (dry weight) in surface sediments, 1.0 μg/liter in river water, and 0.7 μg/liter in delta water. Polyethylene terephthalate (PET) and glass are both widely used materials for bottled drinking water.

This paper provided the first data on the concentration, distribution, congener profile, sources and potential risk of phthalic acid eaters (PAEs) in soil of vegetable fields from the suburbs of Xianyang city, Northwest China. Phthalate esters are commonly used as plasticizers to impart flexibility to plastics, particularly polyvinylchloride polymers (PVCs), which have a wide variety of biomedical and other uses such as building and construction, home furnishings, cars, clothing, and food wrappings.

Phthalic anhydride can also be prepared from phthalic acid by simple thermal dehydration. Recent studies show that DEP, a phthalic acid ester (PAE), is enzymatically hydrolyzed to its monoesters by pancreatic cholesterol esterase (CEase) in pigs and cows. Phthalic Acid Esters: Biological ImpactUncertain Phthalic acid esters-approximately 1 billion pounds in 1972-are widely used in industry, in the home, and in medical sciences.
