The updated Toxic Substances Control Act brings new hope for protecting Americans’ health and environment. Here's what it does — and doesn’t — do.
The fracking industry has been an energy success story: Natural gas prices have decreased as fracking has skyrocketed, and natural gas now produces more electricity than coal does, which has resulted in improved air quality.
As an emergency room physician in Washington, D.C., it didn’t take long for Leana Wen to notice a pattern
Neighbors with the most exposure to natural gas fracking are nearly twice as likely to suffer from some combination of migraine headaches, chronic nasal and sinus symptoms, and severe fatigue.
New research finds that sperm quality in a population of stud dogs studied over a 26-year period had fallen significantly.
"It doesn't matter how old you are or if you're in a wealthy country or a poorer one or if you've had it before—you can get it again," says Sarah M. Bartsch. "And it is really unpleasant. But if we don't focus on norovirus and teach people how to prevent it, little headway will be made to combat it."
A new study of pigeons in New York City shows that levels of lead in the birds track with neighborhoods where children show high levels of lead exposure.
Asthma patients who live near major Pennsylvania fracking sites are as much as four times more likely to suffer attacks than those farther away, a new study shows.
A new study backs up concerns about exposure to the chemical Bisphenol A, or BPA, from food cans and jar lids.
"People who live in rural areas and who use private wells need to have their well water tested, particularly if they are thinking about becoming pregnant," Jean Brender says.
Hospital infections affect almost two million people in the United States every year, 100,000 of whom die. Up to 70 percent of these infections could be prevented if health care workers follow recommended protocols, which include hand hygiene.
Even though most people don’t know much about chemicals in general or poisons in particular, virtually everyone knows that arsenic is bad. In the first century, arsenic was already known to be a deadly poison .
The calls and e-mails arrive as often as several times a week from people with concerns about drinking water. Some of the callers — who include homeowners, architects and builders — want to know why their water smells like gasoline.
Even after taking into account residents' wealth, age, sex, and other neighborhood factors, the study found that having a view of the ocean was associated with improved mental health.
The mice in the enriched environment, where they exercised more, lived anywhere from 16 to 22 percent longer than those in a deprived environment, depending on the level of gene expression.
A good night’s sleep is a crucial aspect to overall health and well-being, yet so many Americans are lacking in that department. A 2013 Gallup poll found that 40% of American adults get less than the recommended amount of sleep.
"This is a global issue rather than one that's simply isolated in China; multidrug resistance is just a plane ride away," says James Tiedje.
People in developed countries turn on the tap and safe drinking water flows, a dramatic health benefit they tend to take for granted. That complacency was dramatically disrupted last year when children in Flint, Michigan, started testing positive for lead poisoning and the source was traced to tap water.
Cockroaches are a very ancient group of insects. They have been around virtually unchanged in general appearance since the Carboniferous period, more than 300 million years ago. Technically speaking they are in the Order Blattodea (the same level of classification as, for instance, all butterflies and moths).
We all suffer from too little sleep from time to time, some more than others. There are many possible reasons, depending on our age, genes and sleep habits; but another possible culprit is using technology before going to sleep.
The Centers for Disease Control and Prevention (CDC) has called insufficient sleep an epidemic. While we are finally paying attention to the importance of sleep, the need for dark is still mostly ignored. That’s right. Dark. Your body needs it too.
For hundreds of years, city planners have developed parks, planted trees and set aside open space in urban environments. Boston Common, a public square used for grazing livestock since 1634, was converted into a park in 1830. A quarter of a century later, New York’s Central Park opened, designed by Frederick Law Olmsted and Calvert Vaux. Olmsted, originally a journalist by trade, went on to develop parks throughout the United States, including in Wisconsin, Colorado, Washington, Georgia and the District of Columbia.
Home alone? Hardly. Our homes are positively swarming with creatures of all kinds. In our new series, we’ll be profiling the “hidden housemates” that live with us.
The explosive spread of Zika throughout the Americas is raising questions about the best ways to control this and future epidemics. We first need to identify what factors contribute to the spread of Zika and understand where and when they occur. With that knowledge we can effectively target our resources to fight the disease and control its spread.
Research worldwide shows that environmentally-friendly buildings are much better for the health of the people who live and work in them, as well as for the Earth.
A new study finds quantifiable evidence that walking in nature could lead to a lower risk of depression. “These results suggest that accessible natural areas may be vital for mental health in our rapidly urbanizing world,” says coauthor Gretchen Daily, professor in environmental science and a senior fellow at the Stanford Woods Institute for the Environment.
In a quest for a perfect tan, many people – especially young white women between age 18 and 25 – may head to a tanning salon, using tanning booths, sunbeds and sunlamps to kick-start their tan. Others (including people who are more prone to burn instead of tan) may head to the salon to slowly develop a “base tan,” with the mistaken belief that it will prevent a sunburn.
The article in The Australian by Liberal Democrat senator David Leyonjhelm highlighted some very good points about wind turbine noise and its effect on people living near them. People are complaining of a range of health related problems and are attributing them to wind turbines. The question is: what is the cause of these health problems?
It’s time to pay attention to a startling stealth killer. What’s the leading cause of death in low- and middle-income countries?
A 2014 review paper in The Lancet Neurology identified a number of potential development neurotoxins in children, including manganese, fluoride, chlorpyrifos, tetrachloroethylene, dichlorodiphenyltrichloroethane and the polybrominated diphenyl ethers.
Today, chemicals comprise the backbone of our modern lifestyle and are the largest sector of our economy. We generate 300 billion pounds of synthetic chemicals each year in the U.S. alone, and an average American uses more than 1,500 pounds of chemical products. Synthetic chemicals are poisoning our bodies from the moment of conception. What are we going to do about it?
Office workers who are exposed to natural light sleep better and are more active compared to workers in windowless offices. Employees with windows in the workplace received 173 percent more white light exposure during work hours and slept an average of 46 minutes more each night.
Hugo and Ross Turner are a pair of intrepid twins currently on an expedition to Greenland. One of them, Ross, is using the same style of equipment and facilities used by Ernest Shackleton 100 years ago in his famous Endurance expedition to Antarctica. He’s having an early 20th century polar expedition diet and pulling a 1900s-style sled.
Scientists and government regulators have long identified many common substances that are neurotoxic in high concentrations, including lead and mercury, and have worked to minimize harm to human communities. But there are many chemicals that may affect the human central nervous system and brain functioning that have not been fully tested, and scientists continue to expand the list of harmful substances.
Last week, the Mercury and Air Toxics Standards was finalized and will protect millions of families and, especially, children from air pollution. Before this rule, there were no national standards that limited the amount of mercury, arsenic, chromium, nickel and acid gases power plants across the country could release into the air we breathe.......
by Sondra Kornblatt. Women show more susceptibility to toxins. On one hand, women’s bodies have more fat, where toxins accumulate, so women are four times more likely to exhibit symptoms of chemical sensitivity than men.......
by Deanna Duke. Back in the 1980s, NASA reported some research it did on the value of indoor plants in cleaning up air quality. Over the years, researchers looked at more than 30 different plants to find the ones that are best at cleaning indoor air...
The idle fields are illuminated by lights from his house, where several men bend intently over a low wooden table as they pore over satellite photographs and contour maps.
Tests show a new air-cleaning system easily removed the rotten egg smells of pig farming and wastewater treatment.
Cars using diesel fuel cause more climate damage than petrol-driven vehicles, campaigners say, and are also a health risk.
The industrial chemical Bisphenol A (BPA) is an ingredient in dozens of everyday products – baby and water bottles, sports equipment, medical and dental devices, dental filling sealants, CDs and DVDs, household electronics, eyeglass lenses, foundry castings and the lining of water pipes. Manufacturers worldwide use at least 3.6 billion kilograms (8
The Flint water crisis and the sad story of Freddie Gray’s lead poisoning have catalyzed a broader discussion about lead poisoning in the United States. What are the risks? Who is most vulnerable? Who is responsible?
The debate about whether or not talcum powder causes ovarian cancer has rumbled on for decades. However, it recently reached fever pitch after a US court awarded damages to the family of a woman who died of ovarian cancer, allegedly as a result of having used talc as a feminine hygiene product for many years. Does that mean women should avoid using talcum powder?
If the U.S. moved to electric vehicles, there would be a substantial cut in air pollution – and health benefits to go with it.In Paris late last year, the countries of the world pledged to reduce emissions to keep global warming “well below a 2 degree Celsius” rise in global average temperatures compared with preindustrial levels.
Recent research has reignited concerns that exposure to chemicals from plastics might be to blame for low sperm counts in young men. I share the concerns about the high prevalence of low sperm counts (one in six young men), and my research is directed at trying to identify what causes it. But whether plastics are to blame isn’t a simple matter.
Common products, including the ones labeled “green,” “all-natural,” “non-toxic,” and “organic,” emit a range of compounds that could harm human health and air quality, according to a new study. But most of these ingredients are not disclosed to consumers.
The headlines were alarming. Traces of cancer-causing contaminants in New Orleans and Pittsburgh public drinking water supplies. Lead from water supply pipes in Boston tap water. In response, in 1974 Congress enacted the Safe Drinking Water Act (SDWA), which was designed to protect public drinking water supplies.
A new study has linked childhood exposure to lead in air and the likelihood of aggressive crimes related to impulsive behaviours in later life.
A new water filter can remove toxic heavy metal ions and radioactive substances in just one pass.
Over the past ten years in the United States, unconventional gas and oil drilling using hydraulic fracturing, or fracking, has experienced a meteoric increase. Since well drilling requires an influx of water, materials and workers into yotherwise rural and remote areas, the question has been: could air, water and noise pollution negatively impact on the health of nearby residents?
We have known for some time the people suffering from schizophrenia and other psychoses smoke more than the general population. The explanation that is usually offered is the so-called “self-medication hypothesis”
Many older people in the U. S. population were chronically exposed to lead from paint and gasoline prior to the 1980s. To date, most of the research on lead and cognitive functioning in older age has focused on men, despite the fact that women live longer on average and therefore may be more likely to develop dementia over the course of their life span.
As the world warms, animals and plants will shift their ranges to keep pace with their favoured climate. While the changing distributions of species can tell us how climate change is affecting the natural world, it may also have a direct impact on us.
A low-cost vaccine against the dengue virus showed promise in an early-stage clinical trial. With further development, the vaccine may help ease the burden of dengue fever in developing countries....
