In order to study the genotoxicity of gaseous formaldehyde（FA）on mouse bone marrow cells,SPF level Kunming male mice were exposed to gaseous formaldehyde for 72h.KCl-SDS assay were applied to detect DNA-protein crosslinks（DPC）in bone marrow cells.Results showed that low concentration（0.5mg·m-3）gaseous formaldehyde could induce DPC formation significantly（compared with the control,p0.05）,and high concentrations（1.0,3.0mg·m-3）could induce DPC formation very significantly（p 0.01）.DPC was increased with the increasing of gaseous forma...
