liver cells of rats exposed to formaldehyde (FA) by inhalation (Im,H.; et al. J. Proteome Res. 2006, 5, 1354-1366). Rats were exposed to 5 and 10 ppm FA for 2 weeks in inhalation chambers. A similar dose-related increase in DNA migration was measured in both cell types. THESE RESULTS ARE INCONSISTENT WITH PUBLISHED DATA CONCERNING FA TOXICITY: (i) Systemic genotoxic effects are reported, whereas previous animal experiments indicated only local effects. (ii) Similar effects were observed in liver cells and lymphocytes despite administration by inhalation. (iii) Increased DNA migration was measured, whereas FA-induced DNA-protein cross-links (DPX) should reduce DNA migration. These three aspects are critically discussed, and the plausibility of the results published by Im and colleagues is questioned.
