Individual fast-screening test systems

As mentioned above several tests can be selected to study the genotoxic potential of substances. As some dozens of assays are currently available, the focus here will be on the most frequently used fast screening assays that can be performed easily in routine biomonitoring programmes (Corbisier et al., 2001). They consti-
