dc.description.abstractA preliminary coldroom experiment was conducted to determine the diffusion rate of several reactive atmospheric chemical contaminants in snow at –7°C. These species included formaldehyde, p-nitrotoluene (PNT), HNO₃, and HCl. Because of detection or contamination problems we could not quantify diffusion rate for formaldehyde, PNT, or HNO₃. However, the diffusivity of HCl in snow (ρ = 0.38 g/cm³) was found to be > 7.7 x 10⁻⁴ cm²/s. This is about two orders of magnitude greater than hitherto expected and suggests that HCl may be rapidly redistributed or lost from seasonal snowpacks. Thus, one should be cautious in interpreting temporal records of HCl and other volatile species in seasonal or polar snowpacks, until their integrity is better established.-
