Distribution of mirex in various compartments of an experimental estuarine ecosystem was determined. Uptake occurred from mirex concentrations in the water that averaged 0.061 plus or minus 0.031 micrograms/liter. Accumulation occurred to the highest degree in the hepato-pancreas of grass shrimp (Palaemonetes pugio) with a concentration factor of 11,000 at the end of 13 days exposure. The hepatopancreas was the only living component to show a clear, continuous increase in concentration of mirex, a trend not revealed by whole-body residues.
