“…For the dichloro congeners, two peaks from FS and one from BCL oil should be similar to those of compounds in CPIs (Indicated by blackedpeaks) from the fact of similarity in their retention time and isotopic abundance ratio (IAR) criteria. These dichloro congeners may be the same compounds to those of dichlorinated monoterpene hydrocarbon reported by Suthridge et al (1990) in two New Zealand's kraft mill effluent. They are tentatively was elucidated having pinane or bonane structures.…”

“…Most probably some toxaphene-like compound precursors enter into that stage and produce polychlorinated monoterpenes in its effluent. Hence, Suthridge et al, (1990) were able to isolate and identify dichlorobornane as well as other chlorinated monoterpene derivatives in chlorination bleaching stage effluent of New zealand's kraft mi115) . We thought that more higher chlorine congeners of polychlorinated monoterpenes, whether of bornane or pinane structure, is likely to be generated too.…”

Toxaphene like compounds, of pinenes origin, from chlorination process were fractionated and used as a reference mixture to survey fishes inhabiting nearby pulp mill effluents. Several congeners, constituent of the fraction, tentatively designated as chlorinated pinenes (CPIs), were detected in fish tissue. For the sake of comparison, Baltic cod liver oil (The Baltic area is known to have toxaphene pollution record) was subjected to the same analyses. Interestingly, some songeners similar to those in CPIs mixture was found in the cod liver oil. Penta and hexachloro congeners found in CPIs mixture and other samples were present in toxaphene. Some congeners are likely to be accumulated in fish with the concentration ratio of fish to effluent as much as 102 to 103. Thus it is probable that pulp mill effluents also contribute to the environmental pollution of toxaphene like compounds. Although total concentration in fish reported here (about 80 ng/g wet weight) was low to cause any health risk, further studies are needed to make clear the state of toxaphene like compounds pollution. Analytical approach demonstrated here is new and useful to determine hiherto unidentified pollutants regardless of the yet unavailable pure standards.

“…Results suggest that not all chlorinated bicyclic monoterpenes found in fish tissue may be the result of chlorinated camphenes or camphanes from toxaphene but from other sources. These may come from the natural product family of bicyclic monoterpenes including pinene and borneol (61).…”

“…Bleachery effluents therefore contain a structurally diverse range of low molecular weight organochlorine compounds. Because of concern about the discharge of such compounds into the environment, and specific evidence for the toxicity-including the genotoxicity (5)(6)(7)(8) of some of them-extensive effort has been devoted to their identification [9][10][11][12][13][14][15][16][17][18][19].…”
