the U.S. military is moving ahead with plans to collect and destroy unused firefighting foam that contains the hazardous chemicals PFOS and PFOA. But in trying to solve one environmental problem related to these persistent chemicals, which have caused massive drinking water contamination, the Defense Department may be creating another. More:

A concentrated formula, diluted with water, forms a heat-resistant foam blanket that rapidly cools and smothers most hydrocarbon-fueled fires. The fluorine content helps create a low-surface-tension film that rapidly spreads across the surface of a flammable liquid. A foam’s quick action in a fire can mean the difference between life and death. As lawsuits pile up and government pressure rises, firefighting-foam makers reconsider the environmental cost of fluorosurfactants. More:

A new study suggests certain types of consumer behaviors, including flossing with Oral-B Glide dental floss, contribute to elevated levels in the body of toxic PFAS chemicals. PFAS are water- and grease-proof substances that have been linked with numerous health problems. The findings provide new insight into how these chemicals end up in people's bodies and how consumers can limit their exposures by modifying their behavior. More:

A purported "eco-friendly" flame retardant breaks down into smaller, possibly harmful chemicals when exposed to heat and ultraviolet light, according to a study from German researchers. The study, published today in Environmental Science and Technology, is the first to show that a popular insulation flame retardant degrades into dozens of smaller chemicals and casts doubt that the "green" flame retardant is as harmless as touted.

Synthetics created in the 20th century have become an evolutionary force, altering human biology and the web of life. Today, PCBs are a notorious class of global pollutants and carcinogens capable of interfering with human fertility, development, cognition and immunity. Though human-made, biology recognises and can even interact with them. PCBs are everywhere, and by design, they endure. Scientists now call most PCBs legacy contaminants – enduring poisons from the past. More:

The closer we look, the more complicated the picture appears. Studies have shown that environmental exposures can modify the expression of genes (without changing the coding sequence), leading to diseases and dysfunctions. This suggests that there are other factors, so far hidden, triggering such a profound increase in these so-called lifestyle disorders. More:

Many popular carpet brands, including those widely used in affordable housing projects, contain toxic chemicals that put people’s health at risk while in use and when the carpets are disposed of, according to a new report by three environmental advocacy groups. The findings are particularly worrisome given that babies and children often spend considerable time crawling and playing on carpets, and they are most sensitive to the potential health consequences from the toxins detected.

New Jersey’s efforts to protect the public from a class of toxic chemicals in drinking water are being threatened by the emergence of substitutes that may be just as hazardous to human health, experts argue. At a public roundtable on PFAS chemicals, scientists said chemical manufacturers have responded to increasing regulation of the chemicals by New Jersey and other states by introducing so-called short-chain alternatives, such as the chemical Gen-X, that serve the same purposes but have not been fully vetted by regulators.

Chemicals are manufactured for use in almost everything with which humans come into contact including food, plastics, personal care products, clothing and building materials.

For parents of small children, car seats are an integral part of day-to-day life. Making sure children are safely buckled and secure is the first step for any car ride, and it helps to ease parent’s minds before hitting the road. However, a new study conducted by researchers from Indiana University and The Ecology Center should serve as a warning for many parents. The researchers found that many child’s car seats contain toxic flame retardants. More:

The contamination is from a class of chemicals referred to as PFAS (perfluoroalkyl and polyfluoroalkyl substances). The chemicals have gotten into water supplies in hundreds of locations across the country and are associated with a range of cancers and serious illnesses in humans, even if they've been exposed to very small amounts.
