Mirex incorporation in estuarine animals, sediment, and water, Mississippi Gulf Coast - 1972-74

Analysis of mirex residues in estuarine animals, sediments, and waters collected from the Missisippi Gulf Coast in 1972-74 showed the following ranges of concentrations: seston, 200-3000 ppb, molluscs, 36-500 ppb; fish, 0-259 ppb; sediment, 3-5 ppb; and water, 0-0.01 ppb. These data indicate that mirex in aquatic environments is localized in animal tissues and bottom substrate and that only a negligible amount is incorporated in the water.
