Absorption and elimination of 14C-cis-chlordane and 14C-photo-cis-chlordane by goldfish Caraccius auratus. 1979

D A Ducat, and M A Khan

Photo-cis-chlordane is accumulated by goldfish to a greater extent than cis-chlordane during a 16-hr exposure to 5 parts per billion (ppb) of each insecticide. However, the concentration of photo-cis-chlordane in vital organs (brain, nervous system, heart, liver, kidneys) during the 1-, 2-, and 4-day exposure is less than that of cis-chlordane. Only the swim bladder shows a much higher concentration of photo-cis-chlordane than cis-chlordane. These differences could hardly account for twice the higher toxicity of the former to goldfish. The transfer of pre-exposed fish to insecticide-free water resulted in faster elimination of photo-cis-chlordane than cis-chlordane; after five weeks, about 90% of the former was eliminated as compared with only 58% of the latter. High residues of both insecticides in the bile and the intestine during the initial period of exposure indicate a biliary route of elimination.

D014018	Tissue Distribution	Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.	Distribution, Tissue,Distributions, Tissue,Tissue Distributions
