Mammalian cell-transforming potential of traffic-linked ultrafine particulate matter PM0.056 in urban roadside atmosphere.

abstract：:In vivo genotoxicity studies-shortly followed by carcinogenicity-are posing high demand for test-related recourses in terms of animal lives and resources. Among those, the micronucleus test in rodents is the most widely used as a follow-up to positive in vitro mutagenicity results; therefore, the development and exten...
