Implications of hormesis for industrial hygieneRohm and Haas Company, Spring House, PO Box 0904, Pennsylvania 19477, USA; rstmaj{at}rohmhaas.com
Rohm and Haas Company, Bristol, Pennsylvania 19007, USA This paper considers hormesis as a valid and potentially valuable alternative hypothesis for low-dose response in the context of occupational health risk assessment. It outlines the current occupational risk assessment paradigm and its use of high-dose toxicological data in setting occupational exposure limits (OELs). This present effort is a call to science to investigate the potential promise of hormesis in providing prima facie experimental evidence for a low-dose threshold of toxic effect to chemical agents. The scientific effort and advancement advised in this piece could also lead to experimentally validated quantitative estimates of the toxic effect extant at occupational exposures in the region of the OEL.
Key Words: hormesis low dose occupational exposure limit risk assessment threshold
