Spectroscopic characterization of environmentally relevant C10-chloroterpenes from a photochemically modified toxaphene standard

Toxaphene Residue Composition as an Indicator of Degradation Pathways

“…Single toxaphene components were isolated from technical toxaphene as previously described (37,32). The soil, a loamy silt (pH 6.7, 1.8% organic carbon), was collected from a field in the surroundings of Kassel.…”

“…The main components of technical toxaphene and the most abundant toxaphene components in environmental samples were isolated and structurally identified, so that data on toxa phene composition as well as residue levels in different environmental samples could be acquired. Today the structure of more than 60 environmentally relevant toxaphene components are known (5,(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34). Toxaphene has been estimated to consist of about 76% chlorobornanes, 18% chlorobornenes, 2% chlorobornadienes, 1% chlorinated hydrocarbons, and 3% nonchlorinated hydrocarbons (35), although the only unsaturated components isolated to date are chlorinated camphenes.…”

Enantioselective Fate of Chiral Chlorinated Hydrocarbons and Their Metabolites in Environmental Samples

“…The selective production of important CTT standards has been achieved by the group of Parlar (190,191) and Nikiforov et al (192). Nevertheless, unlike all other organochlorine compounds discussed in this review, there are more unknown than known CTTs to be detected in environmental samples.…”

Environmental occurrence, analysis, and toxicology of toxaphene compounds.

“…The nomenclature used by Parlar et al is based on gas chromatographic retention on a certain stationary phase (11,77). The nomenclature simply consists of a two-digit code, (Table 3).…”
