NIOSH Testimony on the Environmental Protection Agency's Proposed Rule on Proposed Prohibition of Hexavalent Chromium Chemicals in Comfort Cooling Towers by L. D. Reed, September 27, 1988.
NIOSH 1988 Sep:2 pages
This testimony summarized the current position of NIOSH regarding the health effects from exposure to hexavalent chromium (18540299) (CrVI). The current published policy stated that only the insoluble forms of CrVI are potential human carcinogens. Since these facts were published, however, new scientific evidence has demonstrated the carcinogenic activity of soluble CrVI compounds in exposed animals and has also shown epidemiologic evidence indicating similar carcinogenicity among workers exposed to soluble CrVI compounds. NIOSH now recommends that OSHA consider all CrVI compounds as potential occupational carcinogens.
