Yale researchers have developed a methodology for governments and corporations to determine the availability of critical metals, according to a paper in Environmental Science & Technology. In "Methodology of Metal Criticality Determination," the researchers evaluate the importance of scarce metals using a methodology that determines their supply risk, environmental implications, and vulnerability to supply restriction. "In the past few years, a number of organizations have attempted...

In a first-of-its-kind study, scientists are reporting that the indoor air in offices is an important source of worker exposure to potentially toxic substances released by carpeting, furniture, paint and other items. Their report, which documents a link between levels of these so-called polyfluorinated compounds (PFCs) in office air and in the blood of workers, appears in ACS' journal Environmental Science & Technology. Michael McClean and colleagues explain that PFCs, used in...

Some vacuum cleaners – those basic tools for maintaining a clean indoor environment in homes and offices – actually contribute to indoor air pollution by releasing into the air bacteria and dust that can spread infections and trigger allergies, researchers report in a new study. It appears in ACS' journal Environmental Science & Technology. Lidia Morawska and colleagues explain that previous studies showed that vacuum cleaners can increase levels of very small dust...

In pursuit of riches and energy over the last 5,000 years, humans have released into the environment 385,000 tons of mercury, the source of numerous health concerns, according to a new study that challenges the idea that releases of the metal are on the decline. The report appears in ACS' journal Environmental Science & Technology. David Streets and colleagues explain that humans put mercury into the atmosphere by burning fossil fuels and through mining and industrial processes....

Compounds used in new flame-retardant products are showing up in the environment at increasing concentrations, according to a recent study by researchers at Indiana University Bloomington. The study, published in the journal Environmental Science & Technology, reports on concentrations of two compounds measured in atmospheric samples collected in the Great Lakes region between 2008 and 2010. Authors are doctoral student Yuning Ma, Assistant Research Scientist Marta Venier and...

Water discharged into lakes and rivers from municipal sewage treatment plants may contain significant concentrations of the genes that make bacteria antibiotic-resistant. That's the conclusion of a new study on a sewage treatment plant on Lake Superior in the Duluth, Minn., harbor that appears in ACS' journal Environmental Science & Technology. Timothy M. LaPara and colleagues explain that antibiotic-resistant bacteria – a major problem in medicine today – are abundant in...

Breathing. Anyone reading this article is doing it right now. But what chemicals are we breathing in, and out? A group of Virginia Tech College of Engineering researchers has published a paper in the journal Environmental Science & Technology that details how to learn just that, using microelectromechanical systems to focus on toxins and everyday impurities that enter the body through the air we intake. The research paper, "The Possibilities Will Take Your Breath Away: Breath Analysis...

Concerns that global warming may have a domino effect –unleashing 600 billion tons of carbon in vast expanses of peat in the Northern hemisphere and accelerating warming to disastrous proportions – may be less justified than previously thought. That's the conclusion of a new study on the topic in ACS' journal Environmental Science & Technology. Christian Blodau and colleagues explain that peat bogs – wet deposits of partially decayed plants that are the source of...

University of Illinois scientists report the first identification of a cellular mechanism linked to the toxicity of a major class of drinking water disinfection byproducts. This study, published in Environmental Science & Technology, suggests a possible connection to adverse health effects, including neurological diseases such as Alzheimer's. "I'm not implying that drinking disinfected water will give you Alzheimer's," said Michael Plewa, lead scientist and professor of genetics in the...

Scientists are reporting that household washing machines seem to be a major source of so-called "microplastic" pollution – bits of polyester and acrylic smaller than the head of a pin – that they now have detected on ocean shorelines worldwide. Their report describing this potentially harmful material appears in ACS' journal Environmental Science & Technology. Mark Browne and colleagues explain that the accumulation of microplastic debris in marine environments has raised...
