Abstract: Carbon black(CB) is a stable nano-scale industrial material,which has been widely used in rubber,tires,plastics,batteries,printing and other industries. Due to the small size of CB particles,they can enter the cell and cause damage to genetic material through direct or indirect effects. At present,the International Agency for Research on Cancer classifies CB as a suspected human carcinogen. Most in vitro and in vivo studies have confirmed the genotoxicity of CB. In animal studies,only rats have been tested positive for the carcinogenicity of CB,while the population epidemiological carcinogenic evidence and the studies of genetic damage mechanism of CB are relatively limited. Based on the toxicological data of CB,this paper systematically reviews the characteristics,toxicokinetics,occupational exposure,genotoxicity assessment,genotoxic mechanism and carcinogenic effects of CB,so as to provide scientific basis for the health risk assessment and the formulation of prevention and control measures of CB particles.

Key words: Carbon black particles, Genotoxicity, Oxidative stress, Inflammatory response, Cell cycle, Epigenetic inheritance
