This paper will provide an overview of the potential general applicability of chemical hormesis. Evidence will be presented on the occurrence of chemical hormesis by chemical classes studied (e.g. heavy metals, polycylic aromatic hydrocarbons, etc.), by affected biological and toxic end points (e.g. growth enzyme activities, DNA-repair capacity, life span, tumor incidence) and by biological/taxonomic systems. Several specific examples of possible hormetic effects with respect to agents of environmental concern, such as chloroform, will be presented along with a discussion of future research directions.
