Short-term exposure (for up to 7 days) to all major air pollutants, with the exception of ozone, is significantly associated with an increased risk of heart attack, according to a review and meta-analysis of previous studies appearing in the February 15 issue of JAMA. The potentially harmful effect of episodes of high air pollution on health has been suspected for more than 50 years. "In industrialized countries, cardiovascular disease is the leading cause of mortality and is associated...

For the first time on Saturday, Beijing officials released data disclosing the amount of minute particles polluting the air in what Reuters has called "of the world's most heavily polluted capitals." According to the Xinhua news agency, the Beijing Environment Protection Monitoring Center revealed that a monitoring station in the city detected 0.003 micrograms of fine particular matter of 2.5 micrometers or less in diameter (PM2.5), which equates to an air-quality rating of "good." The...

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...

A study conducted by researchers at Boston University School of Medicine (BUSM) has found that diesel exhaust particulates (DEP) and house dust extract (HDE) causes pulmonary inflammation that aggravates asthma. The study led by principle investigator Jiyoun Kim, PhD, professor of pathology, was published in the December issue of The American Journal of Pathology and was selected by the editorial board as the only article for an in-depth discussion in the journal's commentary section....

Researchers at the National Institute of Standards and Technology (NIST) spent 75 days on the job carrying out some very important homework–measurements in a "typical dwelling" of the release, distribution and fate of particles almost as tiny as the diameter of a single DNA molecule. Particles ranging in size from 100 nanometers down to 2.5 nanometers that were emitted by gas and electric stoves, hair dryers, power tools and candles were tracked and analyzed. Monitoring such tiny...

Scientists at the European Commission's Joint Research Centre (JRC) have identified a shortlist of denaturants that could be used to harmonize denaturing practices at EU level and reduce fraud and tax evasion of alcoholic beverages. The proposed denaturants could potentially replace over 100 different substances currently used in Member States to denature alcohol. Denaturants are used to make alcohol unfit for human consumption and are therefore strong-smelling or bitter-tasting...

GIA announces the release of a comprehensive global report on Methyl Tertiary Butyl Ether (MTBE) market. The global market for Methyl Tertiary Butyl Ether is projected to reach 19.2 million tons by the year 2017, driven primarily by the increased demand from developing countries such as Asia, particularly China, Middle East, and Latin America. Increasing automobile ownership in these countries and use of MTBE as an additive to improve quality of gasoline is expected to fuel consumption of...

A component of garlic oil may help release protective compounds to the heart after heart attack, during cardiac surgery, or as a treatment for heart failure. At low concentrations, hydrogen sulfide gas has been found to protect the heart from damage. However, this unstable and volatile compound has been difficult to deliver as therapy. Now researchers at Emory University School of Medicine have turned to diallyl trisulfide, a garlic oil component, as a way to deliver the benefits of...
