Isoforms of various stress proteins have been shown to be expressed under environmental stress in different tissues in many field species such as fish, mollusks, minnows, sea urchins, insects, and nematodes (see review by Sanders 1993). Through carefully controlled laboratory studies, signature or fingerprint changes could be identified for sentinel species such that a particular metal contaminant could be identified in the field based on a similar response. For example, laboratory studies with the crustacean isopod Oniscus asellus demonstrated hsp70 expression in response to heat treatment and lead (lOOmg/kg). In field studies, O. asellus removed from a polluted site in the vicinity of a lead/zinc smelter similarly demonstrated elevated hsp70 expression (Kohler et al. 1992).
