First year’s analyses results
This shows the results of our first year’s analyses of many of these trace elements. It shows the Millipore filters and Delbag filters that we used, the two different ones, and it ranges for a lot of the elements. You’ll note that many of the numbers we’re using are nano- and pico- and femtograms pe...

It shows the Millipore filters and Delbag filters that we used, the two different ones, and it ranges for a lot of the elements. You’ll note that many of the numbers we’re using are nano- and pico- and femtograms per cubic meter. To my belief, this is the first time we published this data that the unit of femtograms per cubic meter, that’s 10 to the minus 15 grams, were able to be measured. Again, these are the lowest concentrations that have ever been measured on the surface of the planet Earth. We were able to measure them routinely at the geographic South Pole for ten years, but the numbers were extremely small and very low. Elements, for example, like europium, are down at 15 femtograms per cubic meter. What that is, is essentially, 10 to the 5th, 10 to the 6th atoms per cubic meter-very, very low concentrations.
