Fine particle emissions have been the subject of heated debate for years. People who live near industrial plants see the smoke being discharged into the atmosphere and wonder how harmful it is. But visible emissions are not always the most harmful. The highest risk is posed by fine dust particles which can easily penetrate the human organism. These ultra-fine particles are difficult to measure, however, because they are less than 100 nanometers in diameter. Research scientists at the...

Common plants could prove cost-effective alternatives for reducing ozone in offices, homes Ozone, the main component of air pollution, or smog, is a highly reactive, colorless gas formed when oxygen reacts with other chemicals. Although ozone pollution is most often associated with outdoor air, the gas also infiltrates indoor environments like homes and offices. Ozone can be released by ordinary copy machines, laser printers, ultraviolet lights, and some electrostatic air purification...

Popular houseplants, known for reducing volatile organic compounds, also release them into the air, U.S. horticulturalists say. Members of the American Society for Horticultural Science say it is already known plants remove VOCs -- gases or vapors emitted by solids and liquids that may have adverse short- and long-term health effects on humans and animals -- from indoor air. However, the findings about houseplants also emitting VOCs need further study to determine any environmental health...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
