April Flowers for redOrbit.com - Your Universe Online Early morning, deep in the Amazon jungle, fog drifts through the still air. The sun rises and clouds appear to float across the forest canopy. Where do these clouds and mists come from? Water vapor needs soluble particles to condense on, and airborne particles are the seeds of liquid droplets in fog, mist and clouds. To learn how aerosol particles form in the Amazon, an international team of scientists analyzed samples of...

Home Air Check announces that its do-it-yourself home air quality test identifies air pollutants that are of concern to pregnant women. Toxic chemicals like formaldehyde, benzene, toluene, xylene, and others can be emitted into the air as VOCs from many common household products and materials and go undetected, thus increasing the health risks to pregnant women and their unborn babies. The simple indoor air quality test can alert pregnant women of the presence of these potentially harmful...

redOrbit Staff & Wire Reports - Your Universe Online Researchers at NIST's Hollings Marine Laboratory (HML) and four partner organizations have measured for the first time concentrations of 13 perfluoroalkyl compounds (PFCs) in five endangered species of sea turtles. While PFC toxicology studies have not yet been conducted on turtles, the levels of the compounds seen in all five species approach the amounts known to cause unfavorable health effects in other animals. PFCs are...

Young, healthy adult volunteers exposed for two hours to ozone developed physiological changes associated with cardiovascular ailments, according to a small study reported in Circulation, an American Heart Association journal. Study participants showed evidence of vascular inflammation, a potential reduced ability to dissolve artery-blocking blood clots, and changes in the autonomic nervous system that controls the heart's rhythm. The changes were temporary and reversible in these young,...

Researchers from the University of Sheffield's Faculty of Engineering measured air quality inside and outside three residential buildings with different types of energy use (gas vs. electric cookers). They found that nitrogen dioxide (NO2) levels in the kitchen of the city-center flat with a gas cooker were three times higher than the concentrations measured outside the property and well above those recommended in UK Indoor Air Quality Guidance. These findings are published online in Journal...
