The Duluth situation is one well known to this group, and I think it is an excellent example. It is one in which we have natural contributions of ...
متن کاملThe activity of environmental samples in a cell culture test for asbestos toxicity.
The inhibition of colony-forming efficiency of cultured human embryonic intestinederived epithelial (I-407) cells was utilized in order to assay the toxic potential of six coded samples of particulate matter provided by the United States Environmental Protection Agency (EPA). The results of the assay indicated that the most toxic of the EPA samples tested “blindly” was amosite which was equal i...

Bulk Analysis of Environmental Swipe Samples
Bulk analysis of environmental swipe samples taken within nuclear installations as part of routine IAEA inspections has proven to be a very sensitive analytical technique. The combination of chemical separations under very clean conditions with highly sensitive mass spectrometric measurements assists in the identification and characterization of uranium and plutonium signatures at ultratrace le...
