A pair of air pollutants linked to climate change could also be major contributors to the unparalleled rise in the number of people sneezing, sniffling and wheezing during allergy season. The gases, nitrogen dioxide and ground-level ozone, appear to provoke chemical changes in certain airborne allergens that may increase their potency. That, in combination with changes in global climate could help explain why allergies are becoming more common.
Many urban and suburban areas have high levels of ground-level ozone, an air pollutant that can adversely affect lung and heart health. New research in mice suggests breathing high levels of ozone could also affect women’s ability to conceive.
Researchers have found a powerful relationship between prenatal polycyclic aromatic hydrocarbon (PAH) exposure and disturbances in parts of the brain that support information processing and behavioral control.
The industrial metal manganese, once scarce, is now ubiquitous in our environment. New work suggests that it addles honey bees, which often act as sentinel species for environmental contaminants, even at levels considered safe for humans.
Air pollution has been linked to a dangerous narrowing of neck arteries that occurs prior to strokes, according to researchers at NYU Langone Medical Center.
Chlorine, a disinfectant used in most wastewater treatment plants, may be failing to eliminate pharmaceuticals from wastes. As a result, trace levels get discharged from the treatment plants into waterways. Now, scientists are reporting that chlorine treatment may encourage the formation of new, unknown antibiotics that could enter the environment, potentially contributing to the problem of antibiotic resistance. They will present the research at the 249th National Meeting & Exposition of the American Chemical Society.
The sweet taste and smell of antifreeze tempts children and animals to drink the poisonous substance, resulting in thousands of accidental poisonings in the United States every year. But today researchers will describe a new, nontoxic product based on a common food additive that could address this health issue and help the environment at the same time.
A tooth enamel abnormality in children, molar incisor hypomineralization (MIH), may result from exposure to the industrial chemical bisphenol A (BPA), authors of a new study conclude after finding similar damage to the dental enamel of rats that received BPA. The study results will be presented Friday at the Endocrine Society’s 97th annual meeting in San Diego.
Exposure to low doses of hormone-disrupting chemicals early in life can alter gene expression in the liver as well as liver function, increasing the susceptibility to obesity and other metabolic diseases in adulthood, a new study finds. Results of the animal study will be presented Friday at the Endocrine Society’s 97th annual meeting in San Diego.

Male infants whose mothers were exposed during pregnancy to chemicals called phthalates may have a greater risk of future infertility
Laundry detergent pods became available on the US market in 2010 and are easy to use. These pods contain highly concentrated detergents wrapped in a thin film that easily dissolves in water. The appeal and design of laundry detergent pods has already resulted in many reported poisonings among children.
Researchers studying interaction between plants, pollinators and parasites say in experiments where bees infected with an intestinal parasite had reduced parasite loads in the gut after seven days when they had consumed natural toxins present in plant nectar, compared to bees on control nectar.
The objectives of these GLP US EPA OPPTS 970.3800 and 970.3700 studies were to examine the effects of tetrabromobisphenol A (TBBPA) at oral doses of 10, 100 or 1000 mg/kg bw/day over the course of 2 generations on growth as well as behavioral, neurological and neuropathologic functions in offspring.
Houston experienced its hottest summer on record in 2011, resulting in 278 excess emergency department visits per day during the August heat wave, according to research from The University of Texas Health Science Center at Houston (UTHealth) published recently in Environmental Health.
Mercury in seafood – even at low levels generally considered safe – was associated with disease risk factor.
Primary prevention of cancer - that is, stopping cancer before it starts - is possible through changes in environment policy, such as strengthening regulation on air quality and chemicals, including hormone disrupting chemicals. Malta chose to focus on this theme for World Cancer Day 2015. EU Environment Commissioner welcomed the initiative via a video message to the event.
A new study from a researcher at Boise State is among the first to predict a person’s pesticide exposure based on information about their usual diet.
Women whose bodies have high levels of chemicals found in plastics, personal-care products, common household items and the environment experience menopause two to four years earlier than women with lower levels of these chemicals, according to a new study at Washington University School of Medicine in St. Louis. The findings are reported online Jan. 28 in the journal PLOS ONE.
Coating the mouth with BPA-containing food, like soup, does not lead to higher than expected levels of BPA in blood, a new study in Toxicology and Applied Pharmacology shows. The study authors conclude that oral exposure does not create a risk for high exposures of BPA, also known as bisphenol A.
The female hormones estrogen and estradiol may help ward off the effects of lead exposure for young girls, explaining why boys, are shown to suffer more often from the cognitive disabilities linked to lead.
Researchers beginning to understand how antibiotic-resistant bacteria travel aerially.
Nükhet Varlik, a Rutgers historian, has studied the Black Death – the medieval plague that may have wiped out more than half of the population in vast parts of the world – and found echoes from centuries past in issues such as the spread of deadly diseases including Ebola, human interactions with the environment, climate change and other dilemmas that affect human health today as much as they did in the Middle Ages. There is much we may be able to learn about modern times from what Professor Varlik has found.
Exposure to the endocrine-disrupting chemical bisphenol A (BPA) during pregnancy can cause oxidative damage that may put the baby at risk of developing diabetes or heart disease later in life, according to a new study published in the Endocrine Society’s journal Endocrinology.
Coral reef health is declining worldwide. To better understand the combined effects of mosquito pesticides and rising sea-surface temperatures, Dr. Cliff Ross, UNF associate professor of biology, exposed coral larvae to selected concentrations of pesticides and temperatures.
An international team of researchers says climate change, the loss of biosphere integrity, land-system change, and altered biogeochemical cycles like phosphorus and nitrogen runoff have all passed beyond levels that put humanity in a “safe operating space.” Civilization has crossed four of nine so-called planetary boundaries as the result of human activity, according to a report published today in Science by the 18-member research team.

Using a new imaging technique, National Institutes of Health researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. These damaged molecules trigger cell death that produces some human diseases, according to the researchers. The work, appearing online Nov. 17 in the journal Nature, provides a possible explanation for how one type of DNA damage may lead to cancer, diabetes, hypertension, cardiovascular and lung disease, and Alzheimer’s disease.
