Biological effects of arsenic exposure—integration of in vitro genotoxicity data with human biomarker data
Arsenic is one of the few identified human carcinogens that has yet to be shown to cause cancer in rodents (IARC, 1980,1990). Because there is no rodent model that can be used to provide information on the lev...
