Leuenberger et al. Phthalic acid, when found in tissues or biofluids arises from exposure to these phthalate products. It is generally understood that phthalates with backbones of three to six carbons share similar modes of action when it comes to adversely affecting the reproductive system in experimental animals. Table 44.2. Encyclopedia of Endocrine Diseases (Second Edition), Julie Boberg, ... Anne Marie Vinggaard, in, Infants undergoing multiple medical procedures. (2016) detected significantly increased levels of DEHP metabolites in urine 1–2 days after autologous blood transfusions. Possible species differences have been studied using xenografted human testicular tissues. (Ed. Children are among those highest exposed to phthalates, and infants in neonatal intensive care units that are treated with PVC plastic medical devices containing DEHP, can be significantly exposed. However, the FDA has limited the advice to recommendation because the available data have only demonstrated association between exposure to phthalates and effects and not clear cause–effect relationship (Gallinger and Nguyen, 2013). Further to its effect on humans, DEHP has been found to be toxic to other organisms such as plants, marine organisms, and anaerobic microorganisms. In addition to dietary exposure, oral intake of phthalates also occurs when children mouth, suck, or chew on toys containing phthalates (Bouma and Schakel, 2002; Wooten and Smith, 2013). Interestingly, substantial levels of DEHP were also found in blood bags labeled DEHP-free (Leuenberger et al., 2016). products.metrohm.com . Abstract The article contains sections titled: 1. They are found in many plastic consumer products, including adhesives and glues, paints, packaging, children’s toys, electronics, flooring, medical equipment, personal care products, air fresheners, food products, pharmaceuticals, and textiles. Physical Properties 2.2. Long-chain phthalates such as diisododecyl phthalate (DIDP) and diisononyl phthalate (DINP) are abundantly used, and while DIDP does not appear to influence reproductive function or markers of androgen insufficiency in early life, DINP does seem to affect male reproduction via alterations of testosterone production, though with less potency than e.g., DEHP and DBP (ECHA, 2013). DEHP removal during sludge composting, Philippa D. Darbre, in Endocrine Disruption and Human Health, 2015. The most widely used phthalates are di(2-ethylhexyl) phthalate (DEHP), diisodecyl phthalate, and diisononyl phthalate. Phthalates may permeate into humans via inhalation of indoor air in rooms with large surfaces of PVC-containing products (Table 44.1). Being structurally similar, they can present difficulties to reverse-phase HPLC separation. This exposure route is suggested to be of limited importance for adults. This compound reacts violently with nitric acid. As a consequence, the European Union banned the use of DEHP, DBP, BBP, and DIDP in children's toys and child-care items for children below 3 years of age in 1999 (EU Decision, 1999), and in 2005 the European Union prohibited DEHP from all toys and child-care products (EU Directive, 2005). It is claimed that phthalates are never employed in plastic food wraps marketing in the United States. According to literature from the Pediatric Environmental Health Specialty Units program, some advice should be kept in mind to avoid releasing of phthalate from plastic containers: food/beverages and plastic clean wraps should not be heated at microwave in plastic containers and also plastics should not be placed in the dishwasher. The windows of sensitivity appear to differ between rodents and primates (Albert and Jégou, 2014). In addition, adults are exposed to DEHP doses in excess of the tolerable daily intake (TDI) when receiving blood transfusions or during kidney dialysis (Dine et al., 2000; Buchta et al., 2003, 2005; Koch et al., 2005b). ), The Handbook of Environmental Chemistry. Recent studies have found harmful effects of prenatal exposure to DEHP. Oxidation p-Xylol zu TPA.svg 488 × 150; 137 KB. … It is also incompatible with oxidizers. Phytochemical profiling of leaf, stem, and tuber … In vivo, perinatal exposure to DEHP led to increased adipose tissue deposition, serum lipids, glucose, levels, and body weight in offspring (Hao et al., 2013). Indeed, multiple studies in animals, testing various phthalates, showed that phthalate exposure led to increases in body fat and. Phthalic acid is an aromatic dicarboxylic acid, with formula C6H4(COOH)2. It is an isomer of isophthalic acid and terephthalic acid. Uses of the various phthalates mainly depend on their MW. 1,2-benzenedicarboxylic acid synonyms, 1,2-benzenedicarboxylic acid pronunciation, 1,2-benzenedicarboxylic acid translation, English dictionary definition of 1,2-benzenedicarboxylic acid. Typical concentrations of DEHP in various sludge types are listed in Table 4 based on measurements performed in sludge samples taken from four sewage-treatment plants in Seville. Neonates may be exposed to high doses during blood transfusions and other life-saving procedures (Table 44.2) because medical devices for administration of medicines or nutrients may contain high levels of DEHP (20–40%) resulting in mono(2-ethylhexyl)phthalate (MEHP) concentrations several orders of magnitude higher than the general population (Center for Devices and Radiological Health, 2001; Strømmen et al., 2016). In Germany higher levels of DEHP were detected in kindergartens than in apartments (Fromme et al., 2004). Surprisingly, enteric-coated pharmaceutical tablets and nutritional supplements to viscosity control agents also contain phthalates.
