To explore the effects of formaldehyde induced DNA-protein crosslinks （ DPC ） and the repair process of DPC, purebred Kunming mice and HepG2 cell line were used as experimental materials in vivo and in vitro respectively, and KCI - SDS assay were applied to determine the amount of DPC and the repair process. The results in vivo showed that gaseous formaldehyde could cause DPC at high concentrations （l. 0 mg m^-3,3.0 mg· m^-3, p 〈0.01 ） , hut not happened the case at low eoneentrations （0.5 mg·m^-3 ）. DPC induced by gaseous formaldehyde...
