16 May Study: DEHP impairs female fertility and promotes adipogenesis in C3H/N mice. Di-ethylhexyl phthalate (DEHP) impaired fertility in high concentrations and increased body weight and visceral fat depots in female C3H/N mice in environmentally relevant dosages. Environmental Health Perspectives.
15 May Obesity in pregnancy: Carrying too many pounds can give your baby a life of weight problems. Overweight mothers-to-be could be condemning their unborn children to decades of ill health. Babies whose mothers were carrying extra pounds when pregnant are more likely to be fat and unhealthy as adults, researchers say. London Daily Mail, United Kingdom.
14 May Call for Papers: International Journal of Pediatrics. The focus of this special issue is on toxic exposures to children in countries with rapidly developing economies. Manuscripts are due July 13th.
14 May Study: Citywide Smoking Ban Reduced Maternal Smoking and Risk for Preterm Birth. A citywide smoking ban in Colorado provided a natural experiment. The experimental citywide smoking ban site was implemented in Pueblo, Colorado. A comparison community was chosen that had no smoking ban, El Paso County, with similar characteristics of population, size, and geography. This is the first evidence in the United States that population-level intervention using a smoking ban improved maternal and fetal outcomes, measured as maternal smoking and preterm births. Journal of Women's Health.
13 May U.S. Senator Dick Durbin calls for reform on flame retardant chemicals. Reacting with outrage to the Chicago Tribune's investigation of deceptive tactics that have fueled the rise of toxic flame retardants in American homes, U.S. Sen. Dick Durbin on Thursday demanded answers from two federal agencies, urging them to act aggressively to rid homes of chemicals that pose health risks but don't stave off fires. Chicago Tribune, Illinois.
12 May Prenatal smoking tied to worse asthma in kids. Children whose mothers smoked during pregnancy may have a tougher time controlling their asthma than other kids do, a new study suggests. Reuters.
11 May Study: Testosterone-Fueled Infantile Males Might Be a Product of Mom's Behavior. By comparing the testosterone levels of five-month old pairs of twins, both identical and non-identical, University of Montreal researchers were able to establish that testosterone levels in infancy are not inherited genetically but rather determined by environmental factors. Science Daily.
11 May Study: Developmental toxicants and signaling pathways on the migration of human neural crest cells. The migration assay of neural crest assay faithfully models human neural crest migration, and reveals impairment of this function by developmental toxicants with good sensitivity and specificity. Environmental Health Perspectives.
11 May Study: BPA Interferes with Proliferative Activity and Development of Steroidogenic Capacity in Rat Leydig Cells. The presence of bisphenol A (BPA) in consumer products has raised concerns about potential adverse effects on reproductive health. Testicular Leydig cells are the predominant source of the male sex steroid hormone testosterone, which supports the male phenotype. The present report describes the effects of developmental exposure of male rats to BPA by gavage of pregnant and lactating Long-Evans dams. Biology of Reproduction.
11 May Report: Substance Use During Pregnancy Varies by Race and Ethnicity. A new report shows that 21.8 percent of pregnant White women aged 15 to 44 currently (within the past 30 days) smoked cigarettes. The study conducted by the Substance Abuse and Mental Health Services Administration (SAMHSA) also showed that cigarette smoking levels among pregnant White women were significantly higher than the levels among pregnant Black women (14.2 percent) and pregnant Hispanic women (6.5 percent) in the same 15 to 44 age range. Stone Hearth News.
11 May REACH chemical safety review: Re-opening a can of worms? Five years after its adoption, the European Commission is preparing to review the controversial REACH regulation, which for the first time required chemical manufacturers to justify that their products are safe for consumers before placing them on the market. Euractiv, Belgium.
11 May How international chemical regulations are changing American supply chains. Arguments against chemical regulation have been top of mind recently; the odds seem to be stacked against large-scale reform of US legislation. But that doesn?t mean US companies are off the hook when it comes to toxic chemicals. Forbes.
11 May Household chemicals' 'cocktail effect' raises cancer concerns for watchdog. Europe's environmental watchdog, the European Environment Agency, has warned that products containing endocrine disrupting chemicals should be treated with caution until their true effects are better known. The Guardian, United Kingdom.
10 May US scientist: 'Many routes of exposure' to endocrine disruptors. Shanna H. Swan, a renowned scientist specialising in reproductive medicine, has warned about the health effects of endocrine disrupting chemicals known as phthalates which can end up in food via pesticides or plastics. In an interview with EurActiv, she calls on regulators to better protect consumers against those "hidden chemicals". Euractiv, Belgium.
10 May Toxic roulette. A new study of fetal exposure to BPA, a plastic additive found in some food packaging, shows that the chemical altered the mammary gland development in monkeys, reinforcing concerns that BPA - bisphenol A - could contribute to breast cancer in women. McClatchy Newspapers.
9 May Flame retardants investigation: Chemical industry distorts science. Twenty-five years ago, scientists gathered in a cramped government laboratory and set fire to specially designed chairs, TVs and electrical cables packed with flame retardants. For the next half-hour, they carefully measured how much the chemicals slowed the blaze. Chicago Tribune, Illinois.
8 May Study: Trihalomethanes, chlorite, chlorate in drinking water and risk of congenital anomalies. This was the first study showing an excess risk of different congenital anomalies related to chlorite and chlorate exposure via drinking water: further research is needed to confirm the observed relationships in large datasets, specifically for chlorate, an unregulated DBP. Environmental Research.
8 May Food-packaging chemical could lead to breast cancer, study finds. A new study of fetal exposure to BPA, a plastic additive found in some food packaging, shows that the chemical altered the mammary gland development in monkeys, reinforcing concerns that BPA - bisphenol A - could contribute to breast cancer in women. McClatchy Newspapers
8 May Big Tobacco wins fire marshals as allies in flame retardent push. The problem facing cigarette manufacturers decades ago involved tragic deaths and bad publicity, but it had nothing to do with cancer. It had to do with house fires. The industry insisted it couldn't make a fire-safe cigarette and instead promoted flame retardant furniture. Chicago Tribune, Illinois.
5 May Testing shows treated foam offers no safety benefit. The chemical industry's leading trade group says fire-snuffing chemicals "can mean the difference between life and death." But when scientists touched a small flame to a pair of upholstered chairs - one with a flame retardant in the foam and one without- both were engulfed in flames within four minutes. Chicago Tribune, Illinois. [related stories]
