Snow seemed more than pure and clean. After all, it did come from the heavens, didn’t it?
Well, it’s a little more complicated than that.
When snow forms moisture in the atmosphere, it may develop around airborne particles like dust and bacteria. These may include airborne particles from manmade pollution that get caught in the atmosphere. Some of these may include soot and various emissions from factories and automobiles.
Substances used by some states for deicing and melting snow on roads are usually part salt and part chemical. When distributed, especially in bulk quantities, they may have an adverse effect on the local environment with the potential to harm vegetation and contaminate water resources.
