Study: Eating snow is the equivalent of drinking car exhaust

Those of us that go winter camping and who also melt snow for drinking water might be interested in this article. The article is light on details (and I unsuccessfully tried to track down the study that the article references), but it would seem to indicate that snow has the potential to absorb atmospheric pollution and then transmit that pollution to those that eat it (and presumably to those that melt and drink it as well).

Fortunately, the Adirondack backcountry is relatively free of cars, but as we all know, air pollution isn't always localized to the source.
