  • The study, by researchers at the University of Colorado at Boulder and Children's Hospital in Boston, indicates a typical person can safely listen to an iPod for 4.6 hours per day at 70 percent volume using stock earphones, according to Cory Portnuff, a doctoral researcher in CU-Boulder's speech language and hearing sciences department.
  • The researchers found that listening to music at full volume through an iPod for more than five minutes a day using stock earphones can increase the risk of hearing loss in a typical person
  • Typical individuals can tolerate about two hours a day of a decibel unit known as 91-dBA before risking hearing loss, Portnuff said. The term dBA stands for "A-weighted decibels, a scale that takes into account that the human ear has different sensitivities to different frequency levels,"

  • Loud sounds can stress and potentially damage delicate hair cells in the inner ear that convert mechanical vibrations, or sound, to electrical signals that the brain interprets as sound. "Over time, the hair cells can become permanently damaged and no longer work
  • No one set of earphones is more dangerous than another," he said. "While isolator style earphones are capable of producing higher levels of sound than earbuds, most people use them at a lower volume than earbuds because they block out background noise. It's important to monitor the level of volume control settings."

  • The EPA will remove PCBs and TCE from subsurface soils and remove PCBs in two on-site buildings.
  • “This clean-up is absolutely critical because so many children are potentially at- risk across the street at the Herbert Hoover Boys & Girls Club,” said U.S. Rep. Wm. Lacy Clay (D-MO).
  • the agency plans a thermally enhanced extraction of two toxins: trichloroethylene (TCE), a chlorinated industrial solvent, and polychlorinated biphenyls (PCBs), a cancer-causing chemical once used in electrical transformers that were disassembled at a building on the site.

  • The citizen advocacy group is calling for cleanup goals be expanded to cover all areas impacted by Carter Carburetor, the treatment technology to be proven to work on PCBs on similar sites and at similar concentrations before use at the St. Louis site, the risk assessment scenario expanded to include children of all ages and the cleanup plan protect the health of children and area residents.
