Concentrations of Chlordanes (sum of a- and y-) are higher than reported values for other marine food webs in the Baltic Sea (Falandysz et al., 2001). Chlordane concentrations in mangrove fish correspond to the upper range of what has been recorded in various species of fish elsewhere in the Asia-Pacific region (UNEP, 2002). The Chlordane profile was dominated by a- and y-Chlordane in all samples except for crabs and gobies. Falandysz et al. (2001) also noted differences in Chlordane levels between crabs and other marine organisms which were attributed to the potency of crabs to metabolize Chlordane into Oxychlordane. 

Aspila et al. [129] reported the results of an interlaboratory quality control study involving five laboratories on the electron capture gas chromatographic determination of 10 chlorinated insecticides in standards and spiked and unspiked seawater samples (Lindane, Heptachlor, Aldrin, y-Chlordane, a-Chlordane, Dieldrin, Endrin, p,p -DDT, Methoxychlor and Mirex). The methods of analyses used by these workers were not discussed, although it is mentioned that the methods were quite similar to those described in the Water Quality Branch Analytical Methods Manual [130], Both hexane and benzene were used for the initial extraction of the water samples. 

Bioconcentration, Uptake (ka) and Elimination (k2) Rate Constants kj = 340 d (a-, y-chlordane, rainbow trout, Oliver Niimi 1985) k2 = 1.92 d (a-chlordane, rainbow trout, Oliver Niimi 1985) k2 = 0.021 d (y-chlordane, rainbow trout, Oliver Niimi 19850 k2 = 0.0974 d (y-chlordane from rats, Dearth Hites 1991) k2 = 0.1170 d (a-chlordane from rats, Dearth Hites 1991)... 

This method accomplishes the extraction, isolation, and infrared identification of a number of common chlorinated insecticides when present at concentrations of 1-2 p.p.m. or more in fish tissues. In the course of testing the method, certain related observations (noted in Table II) were provided by analyzing fish which were fed insecticides under laboratory conditions. Aldrin was converted largely to dieldrin in both muscle tissue and viscera of a fish exposed to aldrin for 22 days. However, where death occurred in 5 days after a massive dose, the conversion was very slight in the viscera. Heptachlor underwent a significant conversion to heptachlor epoxide, and DDT to DDE. There was also a selective concentration factor—e.g., technical heptachlor (containing y-chlordan) showed a considerably higher ratio of y-chlordan to heptachlor in the fish than in the crude insecticide. Likewise, DDD in...
