...Morawska, a physicist at the Queensland Institute of Technology, and her colleagues analyzed printer emissions in a large open-plan office environment. The good news was that 60% of the printers they tested, including eight HP LaserJet 4050 models, four Ricoh Aficio models and one Toshiba Studio, did not emit any particles. But of the 40% that did, many, such as the HP LaserJet 1320 and 4250 models, were classified as "high-level emitters." Emissions, researchers found, were printer-specific and fluctuated depending on the age of the toner cartridge and the amount of toner a document required...
Nearly 30% believed this, although there is no scientific evidence to prove or disprove the relationship between cell-phone use and brain cancer. The National Cancer Institute continues to study any possible links, but they note that the rapidly changing technology of cell phones (newer phones emit less potential cancer-causing radiation than older models) and the difficulty of documenting the duration of people's exposure could make a definitive answer difficult...
...effectively transforming crowded city streets into private goods. Those who need the roads the most can do so uninhibited by traffic by paying for the privilege. Additionally, cars (especially cars that idle frequently while attempting to negotiate rush-hour gridlock) confer negative externalities due to the pollution they emit. By giving commuters more reason to use alternative methods of transportation, a congestion tax helps bring driving down to a more socially optimal level...
...Following Hurricanes Katrina and Rita, FEMA doled out over 120,000 mobile homes to residents of the Gulf Coast. Many of those trailers have walls and cabinets made up of particleboard, which contains formaldehyde that can sometimes emit gas in hot, humid weather such as that found in Louisiana and Mississippi. The effect on humans (especially children) range from "burning sensations in the eyes, nose, and throat; nausea; coughing; chest tightness; wheezing; skin rashes and allergic reactions." As early as March 2006, FEMA began to receive complaints about formaldehyde odors. After one trailer was tested, an April 2006 e-mail...
...radioactive water used to cool the reactors had spilled, the company suspects, from a spent-fuel pool and into the nearby ocean. Tokyo Electric also announced that 100 drums containing radioactive solid waste were toppled, and some radioactive material was detected in one of the main exhaust pipes that emit the plant's treated emissions into the open air. Prime Minister Shinzo Abe criticized the company for failing to respond quickly enough in the quake's aftermath. Tokyo Electric President Tsunehisa Katsumata apologized, saying "We were not aware of the dangers." He added that Monday was a national holiday, which...
