Applicability of Corbicula as a bioindicator for monitoring organochlorine pesticides in fresh and brackish waters

“…Compositions of technical chlordane in Japan were measured in this study as cis-chlordanetrans-chlordane-cis-nonachlor-trans-nonachlor = 16:18:4.5:14 and were similar to those in technical chlordane in the international market (Buchert et al 1989;Sovocool et al 1977). In western Japan, cis-chlordane/trans-chlordane ratios in water, Corbicula, and sediment were higher than those in technical chlordane (0.89): 1.2 (0.50-2.1), 1.4 (1.1-2.1), and 1.1 (0.75-1.5) (Fig.…”

Evaluation of Volatilization Potential for Legacy Chlordane in Military Housing Area Soils

“…Of the many related compounds, about 10 are major components including: trans-chlordane, cis-chlordane, ß-chlordene, heptachlor, and trans-nonachlor. The cis-and trans-isomers of chlordane ( Figure 1) make up 60-85% of the commercial mixture depending on the manufacturing process (Buchert et al 1989). Chlordane does not dissolve in water; therefore, before it can be used as a spray, it must be placed in water with emulsifiers, which results in a milky-looking mixture.…”

Opinion of the Scientific Panel on contaminants in the food chain [CONTAM] related heptachlor as an undesirable substance in animal feed

“…Heptachlor (1,4,5,6,7,8,4,7,; C 10 H 5 Cl 7 ) was first identified in 1946 as a constituent of technical chlordane of which heptachlor constitutes about 10 % (Buchert et al, 1989;Buser and Müller, 1993;NRCC, 1974). Heptachlor has a 3 -5 times greater insecticidal activity than technical chlordane and was later used as an insecticide on its own (Kirk-Othmer, 1981).…”
