Abstract: | Residue analysis of toxaphene has been difficult because of the complexity of the technical mixture consisting of a high number of compounds with very similar structure and differing chlorine content. Furthermore, the composition of toxaphene in environmental samples varies widely and is normally not related to that of the technical mixture. Therefore, quantification of single components in environmental samples was impossible. After the isolation and identification of a great number of components during the last decade, enough standards are available for the reliable quantification of toxaphene in all environmental compartments. Recently, most research has been performed on the separation of chiral components of toxaphene with a view to identifying the degradation mechanisms and distribution pathways. |
