  • Effects of pesticides on occupationally exposed humans 

    Piperakis, S. M.; Kontogianni, K.; Piperakis, M. M.; Marcos, R.; Tsilimigaki, S. (2006)
    Pesticides are known to contain numerous genotoxic compounds; however, genotoxicity biomonitoring studies of workers occupationally exposed to pesticides have produced variable results. In this study, we employed the Comet ...
