evidence: Barium-induced health effects appear quickly following high-level acute exposure. Symptoms usually resolve soon after exposure ceases. Chronic exposure may result in kidney damage. [...] More information about barium can be obtained from your regional poison control center; your state, county, or local health department; the Agency for Toxic Substances and Disease Registry (ATSDR); your doctor; or a clinic in your area that specializes in occupational and environmental health. If the exposure happened at work, you may wish to discuss it with your employer, the Occupational Safety and Health Administration (OSHA), or the National Institute for Occupational Safety and Health (NIOSH). Ask the person who gave you this form for help in locating these telephone numbers. [...] ATSDR. 2005. Toxicological profile for barium and barium compounds (draft for public comment).
