Pheretima posthuma

Glutathione S-transferase (GST). The induction and activities of GST, like the phase 1 enzymes above, have been measured as a potential biomarker of exposure to organic contaminants. In earthworms, Stokke and Stenersen (1993) found no increase of GST in E. andrei following exposure to three classic inducers (trans-stilbene oxide, 3-methylcholanthrene and l,4-bis[2(3,5-dichloropyridoxyl)]ben-zene) for 3 days, a result confirmed by Borgeraas et al. (1996) for both E. andrei and Eisenia veneta. In contrast, Hans et al. (1993) found induction of GST in another earthworm Pheretima posthuma following exposure to aldrin, endosul-phan and lindane. However, this induction was transient, which may explain some...
