Bisphenol A (BPA) News and Research

RSS

Bisphenol A (BPA) is a chemical produced in large quantities for use primarily in the production of polycarbonate plastics and epoxy resins. Polycarbonate plastics have many applications including use in some food and drink packaging, e.g., water and infant bottles, compact discs, impact-resistant safety equipment, and medical devices. Epoxy resins are used as lacquers to coat metal products such as food cans, bottle tops, and water supply pipes. Some dental sealants and composites may also contribute to BPA exposure.

Bisphenol-s and bisphenol-f may have less impact on heart function than bisphenol-a

Some chemical alternatives to plastic bisphenol-a (BPA), which is still commonly used in medical settings such as operating rooms and intensive care units, may be less disruptive to heart electrical function than BPA, according to a pre-clinical study that explored how the structural analogues bisphenol-s (BPS) and bisphenol-f (BPF) interact with the chemical and electrical functions of heart cells.

Higher levels of chemicals in mothers' system during pregnancy linked to lower IQ in children

Exposure during the first trimester of pregnancy to mixtures of suspected endocrine-disrupting chemicals found in consumer products is related to lower IQ in children by age 7, according to a study by researchers at the Icahn School of Medicine at Mount Sinai and Karlstad University, Sweden, published in Environment International in October.

Exposure to BPA in the womb may lead to measurable differences in children's lung function

Pregnant women exposed to higher levels of the commonly used chemical bisphenol A (BPA) are more likely to have children who suffer with wheezing and poorer lung function, according to research presented at the European Respiratory Society International Congress.

BPA exposure during pregnancy can lead to changes in circadian rhythms

Exposure to the widely used chemical bisphenol A during pregnancy, even at levels lower than the regulated "safe" human exposure level, can lead to changes in circadian rhythms, according to a mice study to be presented Monday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La. The researchers report these changes may be a contributing factor in hyperactivity seen in BPA-exposed mice.

Prenatal exposures to BPA may pose threat to human ovarian function

While previous studies have shown the adverse health effects of prenatal exposure to the industrial chemical bisphenol A, there is little evidence surrounding effects specifically on ovarian function.

No scientific reason available to assume link between BPA uptake and MIH in children

Depending on symptomatic and phenotypic severity the condition of chalky teeth is categorised into three levels. The symptoms of chalky teeth were first described in 1978, with the term molar-incisor hypomineralisation introduced in 2001.

BPA-free plastic not safe either finds study

We look for labels stating plastics are “BPA-free” to reassure ourselves that the product is safe to eat or drink out of. A new study has shown that BPA-free options are not safe either.

Special issue focuses on how endocrine-disrupting chemicals influence behavior

Rutgers School of Public Health Professor Dr. Emily Barrett, PhD, and North Carolina State University Professor Dr. Heather Patisaul, PhD, have guest edited a special issue of the journal Hormones and Behavior.

Mice study shows how BPA exposure during pregnancy can lead to altered brain development

New research in mice provides an explanation for how exposure to the widely used chemical bisphenol A during pregnancy, even at levels lower than the regulated "safe" human exposure level, can lead to altered brain development and behavior later in life.

Environmental triggers may play role in development of Lupus

While genetics play a role in the development of Lupus, a systemic autoimmune disease that can attack any organ system in the human body, so do environmental triggers, such as particulates in air pollution and ultraviolet light, explains Gaurav Gulati, MD, a physician-researcher at the University of Cincinnati College of Medicine.

Exposure to BPA during pregnancy may lead to long-lasting health problems in offspring

A chemical called bisphenol A -- BPA -- used in plastic packaging and in the linings of food and beverage cans, may be passed from a mother to her offspring during pregnancy and cause changes in the gut bacteria of the offspring, according to an international team of researchers.

Study shows effects of prenatal BPA exposure at low levels in developing rodent brain

New research from North Carolina State University reveals that prenatal exposure to bisphenol A (BPA) at levels below those currently considered safe for humans affects gene expression related to sexual differentiation and neurodevelopment in the developing rat brain.

UofL gastroenterologist receives NIEHS award to explore effects of environmental chemicals on the liver

UofL gastroenterologist Matthew Cave, M.D., believes that chemicals we breathe, consume or come in contact with in the environment may be contributing to liver disease in as many as one in four people. He has been awarded $4.01 million over eight years by the National Institute of Environmental Health Sciences, one of the National Institutes of Health, to explore the long-term effects of environmental chemicals on the liver.
