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 .
Almost every product we purchase, use in our homes or give to our children contains tens, if not hundreds, of chemicals. The United States chemical industry alone produced US$769.4 billion worth of chemicals in 2012.
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.
The Dutch famine of 1944 was a terrible time for many in the Netherlands – with around 4.5m people affected and reliant on soup kitchens after food supplies were stopped from getting into the area by German blockades. As many as 22,000 people were thought to have died, and those who survived would find...
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 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?
A new water filter can remove toxic heavy metal ions and radioactive substances in just one pass.
The ongoing water crisis in Flint, Michigan has highlighted just how harmful lead contamination is. What you may not realize, however, is that lead exposure is a problem throughout the U.S.
What do you know about your endocrine system? Possibly not as much as you should, seeing as how almost every organ and cell in the body is affected by it. This under-appreciated collection of glands selects and removes materials from the blood, processes them and secretes the finished chemical products, or hormones, back into the bloodstream.
Alongside the day’s high and low temperatures, weather reports generally contain a UV alert for a particular time. But what does it actually mean – and what should you do about it?
Researchers report that the children of mothers who experienced higher levels of exposure to perfluorooctanoic acid while pregnant had higher body fat and faster weight gain through age 8. The participants live downstream from a chemical plant that used PFOA.
"It's kind of ironic. In our laboratory, working with carbon nanotubes, we wear facemasks to prevent exactly what we're seeing in these samples, yet everyone walking around out there in the world probably has at least a small concentration of carbon nanotubes in their lungs," says Lon Wilson.
Mercury pollution is one of the most insidious problems in our environment. Today my colleagues and I at Flinders University have unveiled a new material than can scrub mercury from the environment, as a result of research to be published this week.
We all know about the obvious dangers of DIY and construction work – smashed thumbs, stubbed toes and so on. Even hanging wallpaper results in 1,500 British people going to hospital every year.
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?
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.
Exposure to air pollutants during pregnancy may contribute to childhood abnormalities in the brain, a new study suggests. The research, from the Children’s Hospital of Los Angeles, measured the exposure of the mothers to PAH air pollution and used brain imaging to look at the effects on their children’s brains.
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.
Environmental chemicals are wreaking havoc to last a lifetime. 10 to 15 percent of all babies born in the U.S. have some type of neurobehavorial development disorder. Still more are affected by neurological disorders that don’t rise to the level of clinical diagnosis.
Purchase a plastic water bottle, and there’s a good chance that it will feature a “BPA-free” label. You might be seeing it more often because the industrial chemical Bisphenol-A has now been removed from a wide array of products.
As average temperatures rise an increasing global population – with many more elderly people – is going to be more vulnerable to extreme weather, UK scientists say.
Bad news for hay fever and asthma sufferers as US researchers demonstrate that man-made rises in CO2 emissions could lead to a 200% increase in the levels of pollen from grasses.
Recent analyses raise disturbing questions about the health and environmental effects of the stuff that encases our edibles.
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...
Toxicologists have a saying: “The dose makes the poison.” In other words, there is no such thing as “toxic” or “non-toxic” — it always depends on how much of a substance you consume.
On a low, windswept rise at the southeastern edge of the Navajo Nation, Jackie Bell-Jefferson prepares to move her family from their home. A mound of uranium-laden waste the size of several football fields, covered with a thin veneer of gravel, dominates the view from her front door...
It would seem, and particularly for mothers, fathers, and grandparents everywhere, that using plastics for anything other than decorations is not at all wise. Just what would be your decision if you knew that what you were feeding your children, or your grandchildren, might one day lead to...
As a new report highlights the link between warming waters and mercury pollution, scientists fear for contamination to the marine food chain. Scientists in the US say they have found evidence suggesting that warmer sea surface temperatures may increase the ability of fish to accumulate mercury.
The health risks of leaded gasoline are a thing of the past, right? Wrong. When the Oregon Department of Environmental Quality surveyed the airport in 2005, it found a lead cloud hovering above Hillsboro, a circular plume spanning 25 square miles. At its center lead levels were twice as high as the National Ambient Air Quality Standard threshold...
Our primal mind has no defense against the stressful world it now faces, and we are paying a terrifying price for it. The toll this takes is insidious as well as profound, and it must be appreciated if steps are to be taken to mitigate its effects...
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.
Bacterial communities called biofilms can quickly clog medical devices such as stents and catheters by forming 3-dimensional streamers that block flow. The finding will inform future approaches to prevent these deadly clogs....
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.
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....
There are legitimate questions about soy. To my mind, by far the most disturbing one stems from the fact that 90 percent of the U.S. soybean crop today is genetically engineered. Because so much Roundup is used on these crops, the residue levels in the harvested crops greatly exceed what, until very recently, was the allowable legal limit...
(Do you think your tap water is only water? Think again.) The major contaminants that the EPA requires testing for include benzenes, vinyl chloride, BPA, triclosan, DEET, mercury, cadmium, perchlorate, phthalates, DDT, PCBs, atrazine and other pesticides, E. coli and fecal coliforms. Other contaminants...
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...
by Debra Lynn Dadd. The following are some tried-and-true methods for removing toxic chemicals from your body, which will help relieve your body's toxic burden...
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.
BPA is in many of the products we eat and drink regularly. It is so common that the CDC estimates that 93% of Americans have BPA in their bloodstream. One of the most common products containing BPA and the one of most concern is canned food.
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.
Warnings about the dangers of estrogen had been made sporadically for nearly 30 years. In particular, it was known that estrone, the form of estrogen in Premarin, could be associated with the development of endometrial cancer. Many of us don't recognize when we may have been given the wrong type of hormone. We are completely...
We are living in a world where environmental pollution has become part of life. Civilized humans today must live in cramped urban areas, drink contaminated water, take in polluted air, eat contaminated foods, and endure loud, disturbing noises. What can we do?
With temperatures rising in the East and Midwest, the number of deaths attributed to excessive heat exposure is climbing also. But most tragedies can be avoided by taking a few precautions
