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.

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.

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.
