###### Beryllium is an tremely lightweight metal that is used in many industries, such as aerospace and electronics. Long-term exposure to beryllium can cause people to become sensitized Once an individual is sensitized, continued exposure can result in chronic beryllium disease, which involves scarring of the lungs In a study of the effects of exposure to beryllium; workers were categorized by their duration of exposure (in years) and by their disease status (diseased, sensitized, or normal) The res
