Designing a Beryllium Exposure- and Disease

Beryllium sensitization (BeS), chronic beryllium disease (CBD), and lung cancer are the principal health concerns related to exposure to beryllium. Because of a lack of quantitative risk information on low exposure and uncertainties associated with factors that contribute to the development of CBD (see Chapter 3), the committee was unable to identify a chronic inhalation exposure level that is ...
