    Slide is looking at the enrichment factors relative to the ash of Mount St. Helens or the plume samples that were collected. These are looking at the samples from the May 19th flight right after the eruption as compared to the September 22nd flight which was in the P3. As you can see from the enrichments, the May 19th enrichments are all black and they are down on the bottom with very low enrichments, essentially with just ash blown into the air by the phreatic explosion of the steam. The next group of open bars are the ones in white for September. Those show very high enrichments, up to ten thousand fold for the elements. For example, arsenic, mercury, and silver showed extremely high enrichments. Some of the elements that are more refractory do not show any enrichments, but most of the ones that do have some volatility or the compounds that are volatile show fairly high enrichments. less
