Cigarette smoking, forest fires and woodburning can release a chemical that may be at least partly responsible for human health problems related to smoke exposure, according to a new study by NOAA researchers and their colleagues. Using a custom mass spectrometer designed by the researchers, the NOAA-led team was able get the first look at levels of the chemical, isocyanic acid, in the atmosphere. Isocyanic acid has been difficult to detect with conventional measurement techniques. "We found...

All animals face the challenge of deciding which chemicals in the environment are useful and which are harmful. A new study greatly improves our understanding of how animals sense an important class of potentially harmful chemicals: weak acids. The study appears online on May 16 in the Journal of General Physiology (www.jgp.org). Weak acids like acetic acid (vinegar) and propionic acid (present in fermented foods like Swiss cheese) are shunned by many animals, and with good reason. Many...

PHILADELPHIA, Feb. 24, 2011 /PRNewswire-USNewswire/ -- Four local ironworkers, all suffering injuries from exposure to hydrofluoric acid (HF) in March 2009, are alleging that Sunoco and its subcontractors knew the long troubled South Philadelphia Refinery's Unit 433 was an accident waiting to happen and failed to protect them from harm. The workers, James Jamison, Eric Konopka, Gerald McGoldrick, and Jamie Miceli, members of the same specialized maintenance crew assigned to the Unit...

University of Toronto scientists have found that chemicals used to line junk food wrappers and microwave popcorn bags are migrating into food and being ingested by people where they are contributing to chemical contamination observed in blood. Perfluorinated carboxylic acids or PFCAs are the breakdown products of chemicals used to make non-stick and water- and stain-repellant products ranging from kitchen pans to clothing to food packaging.  PFCAs, the best known of which is...

Current computer models may underestimate levels of ground-level ozone A team of scientists has, for the first time, completely characterized an important chemical reaction that is critical to the formation of ground-level ozone in urban areas. The team's results indicate that computer models may be underestimating ozone levels in urban areas during episodes of poor air quality (smoggy days) by as much as five to 10 percent. Ground level ozone poses significant health hazards to people,...

Mapping the structure of protonated water clusters Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures and chemical properties of protonated water clusters. In order to measure the spectrum of molecular vibrations in clusters it is, however, necessary...

Using a chemical trick that allows them to change the acidity of a solution almost instantly, a team at the National Institute of Standards and Technology (NIST) has demonstrated a simple and effective technique for quantifying how the stability of nanoparticle solutions change when the acidity of their environment suddenly changes*. The measurement method and the problem studied are part of a broader effort at NIST to understand the environmental, health and safety implications of...

Sulfur (or Sulphur; see spelling below) is the chemical element in the periodic table that has the symbol S and atomic number 16. It is an abundant, tasteless, odorless, multivalent non-metal. Sulfur, in its native form, is a yellow crystaline solid. In nature, it can be found as the pure element or as sulfide and sulfate minerals. It is an essential element for life and is found in several amino acids. Its commercial uses are primarily in fertilizers but it is also widely used in gunpowder,...
