Influence of anthropogenic substances on the germ cell mutation rate   

Markus Pfenninger

SUMMARY

Tests of mutagenicity are currently performed with single celled eukaryotes or prokaryotes (e.g. ISO 13829 (2000); ISO 16420 (2005) or conclude from phenotypic effects on mutagenicity of substances. Since the mutation and repair mechanisms of multicellular eukaryotes (including our species) differs substantially, the transfer of the results from these test is questionable and remains untested. The development of a new method now allows the inference of mutation rates with reasonable effort. Genom-wide screening for base substitutions, deletions, insertions and chromosomal aberrations promises a far higher sensitivity than current mutagenicity tests. It is our goal to establish a new paradigm in the ecotoxicological assessment of anthropogenic substances in international frameworks (e.g. ISO). To achieve this, we will work with the genomes of ecotoxicological model species like Chironomus riparius, Folsomia candida, Eisenia andrei and Daphnia galeata. .
