NEGATIVE ION CHEMICAL IONIZATION MASS SPECTROMETRY - A USEFUL TECHNIQUE FOR THE SELECTIVE DETECTION OF POLAR SUBSTITUTED POLYCYCLIC AROMATIC HYDROCARBONS WITH MUTAGENIC PROPERTIES.

Abstract

Earlier studies have shown that many compounds with toxic properties are able to form stable negative ions. The negative ion mass spectrometric response of polar substances found in indoor air extracts from aluminium smelters was determined and compared with available mutagenicity data. The results indicate that the relationship mentioned above also is valid for polar compounds.
