Introduction Phthalates are chemical additives incorporated in PVCbased materials to make them more pliable. Intensive care management, especially in the pediatric setting, relies heavily on the use of soft and flexible indwelling medical devices. As phthalates are not chemically bound to these devices, they can leach during use [1,2]. Environmental phthalate exposure has been associated with a...
Phthalates, or phthalic acid ethers, are hazardous for human health as they produce negative effects on the endocrine system and liver when entering a body. Alimentary introduction into a body with food products is priority phthalates. Phthalates contents in milk of particular interest since most popular product among population. It vital to assess whether ph...
Some phthalates such as di(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP) and their metabolites are suspected of producing teratogenic or endocrine-disrupting effects. To predict possible human exposure to phthalates in cosmetics, the levels of DEHP, diethyl phthalate (DEP), DBP, and butylbenzyl phthalate (BBP) were determined by high-performance liquid chromatography (HPLC) in 102 ...
background: early puberty is a common worldwide problem. different parameters as genetics, metabolic diseases, obesity, as well as environmental factors may affect the age of puberty. this systematic review aims to survey the related literature on the effects of environmental pollutants and especially organohalogens and phthalates on early puberty. materials and methods: a systematic review of ...
A simple and reliable colorimetric method for determination of phthalates is developed utilizing uridine-5'-triphosphate (UTP)-modified gold nanoparticles as a color indicator and Cu(2+) as a cross-linker. The method demonstrates superior sensitivity with a detection limit of phthalates of ca. 0.5 ppm.
Background: In many developing countries, numerous brands of bottled water and the relatively cheaper counterpart, sachet water, can be found in all cities, towns, and even villages. This study assessed the concentrations of some phthalates and metals in bottled and sachet water sold in Lagos, Nigeria. Methods: Fifteen pieces of plastic bottled water and 15 pieces of sachet water were randomly...
Phthalates are plasticizers that are added to polyvinyl chloride (PVC) products to impart flexibility and durability. They are produced in high volume and generate extensive though poorly defined human exposures and unique childhood exposures. Phthalates are animal carcinogens and can cause fetal death, malformations, and reproductive toxicity in laboratory animals. Toxicity profiles and potenc...
Phthalates are a group of multifunctional chemicals used in consumer and personal care products, plastics, and medical devices. Laboratory studies show that some phthalates are reproductive and developmental toxicants. Recently, human studies have shown measurable levels of several phthalates in most of the U.S. general population. Despite their widespread use and the consistent toxicologic dat...
The current study evaluates the migration of benzene, toluene, ethylbenzene, xylene (BTEX) and phthalates into artificial saliva from natural rubber latex (NRL) balloons available for sale in Sri Lanka. It was discovered that at least one BTEX compound migrated from almost all the brands. The migration of four phthalates; diethyl phthalate, dibutyl phthalate, di-isobutyl phthalate and butyl ben...
An analytical method has been developed for the simultaneous extraction and determination of trace tertiary octylphenol (t-OP), technical nonylphenol isomers (NP), nonylphenol monoethoxylate isomers (NP1EO) and seven phthalates in sea water and the atmosphere using gas chromatography-mass spectrometry (GC-MS). Large volume samples were collected using a modified in-situ pump equipped with a PAD...
