“…Like many other organochlorine pesticides (e.g. DDT, dieldrin, lindane), it is considered a major environmental contaminant (Callahan et al 1979, Mowbray 1988 because of its worldwide distribution (Murty 1986, Kawano et al 1988, its persistence in both terrestrial (Watanabe 1973, Parker et al 1985 and aquatic ecosystems (Sanborn et al 1976, Oloffs et al 1978, Wood et al 1986, its toxicity to a wide range of non-target organisms (Parrish et al 1976, Cardwell et al 1977, Mayer & Ellersieck 1986, Srivastava & Srivastava 1988 and its accumulation and biomagnification O Inter-ResearchIPrinted in Germany through the food chain (Butler 1971, Jansson et al 1979, Kerkhoff & De Boer 1982, Moilanen et al 1982, Kawano et al 1988, Norstrom et al 1988. Mass spectral studies have shown that technical chlordane is comprised of more than 140 different chlorinated hydrocarbons (Dearth & Hites 1991).…”

As part of a study designed to assess the impact of the pesticide technical chlordane on marine infauna, a 3 mo field trial was conducted to identify sensitive species and life stages and to determine the time-scale of their response. Technical chlordane was applied to a hitherto uncontaminated site to achieve a near-surface sediment concentration of about 7.5 ng (g dry fines)-' After 5 to 13 tidal cycles, the density of common infaunal suspension and deposit feeding bivalves began to decline and continued to do so for at least a further 31 tides. Populations of Chione stutchburyi and Tellina liliana decreased to about 30 and 40 % respectively of their initial densities. Analysis of the size structure of the 2 populations showed that the decrease resulted primarily from the loss of juveniles 0.5 to 2.5 mm in size. Juveniles within this size range gradually repopulated the site between Tides 44 and 112, when chlordane residues in the near-surface sediment dropped to 3 ng (g dry fines)-' following a storm. Numerous post-metamorphic specimens of Chione stutchburyi (76) and Tellina liliana (163) were caught in drift nets placed around the study area, suggesting that the mobility of post-settlement juveniles may play an important role in reducing the density of small shellfish in contaminated sediment. The potential movement of post-settlement juveniles away from contaminated sediments could provide a useful technique for impact assessment.

“…Chlordane and derivatives seem to be widely distributed in the environment. For example, these compounds have been found in fish from the North Sea, the Baltic, and, more surprisingly, from Lake Vattern in Sweden, although this type of preparation is not known to have been used in Sweden (Jansson et al, 1979).…”

“…The same separation is achieved by adsorption chromatography with activated 5i02 gel using isooctane for the first eluens and benzene as the second [33,34] Volatile halocarbons The standard cleanup includes hexane/dimethylformamide partition followed by adsorption chromatography on either Florisil [281 or Si02 gel [35] with hexane or isooctane as eluents. Elemental sulfur is also found in this fraction, and can be removed by an activated silver column [201. In extreme trace analysis of PCB the biologically modified pattern can be used as a check for contamination during the working-up procedure [301.…”
