  • T he 1986 National Research Council (NRC) report on commercial airliner cabin air quality notes that information regarding the environmental characteristics (e.g., relative humidity and air pressure) and contaminants identified in surveys of airline cabin air "suggests a diverse set of adverse health effects that could arise from exposure to the cabin environment-from acute effects…to long-term effects. (nationalacademies.org)
  • Any consideration of health effects in the context of airline cabin air must distinguish between effects of exposures that result from the ambient environment encountered during boarding, waiting at the gate with the aircraft door open, and normal operation of the aircraft and effects of exposures that result from incidents during flight.

  • The Portage resident believes he's sick from the chemicals in fracking fluid and from radiation exposure. (blogspot.com)
  • Research has shown that exposure to certain chemicals in the workplace may also negatively affect how the ear functions, potentially causing hearing loss or balance problems, regardless of noise exposure. (cdc.gov)
  • The fact that noise exposure is so common in modern societies might explain the delay in recognizing the risk to hearing that these chemicals can pose. (cdc.gov)
  • Phosgene's irritating quality can be mild and delayed, which may result in a lack of avoidance leading to exposure for prolonged periods. (cdc.gov)
  • Undetected or unsuspected CO exposure can result in death ( 1 ). (cdc.gov)
  • Most signs and symptoms of CO exposure are nonspecific (e.g., headache or nausea) and can be mistakenly attributed to other causes, such as viral illnesses. (cdc.gov)
  • Narratives were also reviewed to determine CO source, exposure status (on the basis of physician diagnosis), and symptoms reported. (cdc.gov)
  • CO sources (e.g., furnaces, generators, gas heaters, and motor vehicles) are common in homes or work environments and can put persons at risk for CO exposure and poisoning. (cdc.gov)
  • The prevalence of hearing impairment and risk ratios varied across sites and trade groups, which was accounted by the difference in exposure and other risk factors. (cdc.gov)

  • An incident was identified as a case if 1) the intent of injury was unintentional or undetermined, 2) the principal diagnosis by a physician was 'poisoning' or 'anoxia,' and 3) the consumer product indicated was 'CO detector' or 'CO poisoning (source unknown)' or a brief narrative abstracted from the medical record indicated either CO exposure or CO poisoning. (cdc.gov)
  • During 2001--2003, an estimated 15,200 persons were treated annually in EDs for nonfatal, unintentional, non--fire-related CO exposure, and, during 2001--2002, an average of 480 persons died each year from unintentional, non--fire-related CO exposure ( Table 1 ). (cdc.gov)
