Concern about the potential mutagenic and carcinogenic effects of genotoxic agents in populations exposed to MMA occupationally has grown, partially due to the possibility that mutagenic effects may occur only after multiple years of exposure, increasing the incidence of cancer and characterizing so-called cumulative effects.
