Accumulation and retention of mirex by brook trout fed a contaminated diet

Bioconcentration factors of some halogenated organics for rainbow trout: limitations in their use for prediction of environmental residues

“…OCN also appears to have a very low fe1; close to that of mirex, and decachlorodiphenyl ether, an even larger, heavier molecule, was not detected in any of the fish. It appears that these large molecules are not efficiently transferred across the gill membranes even though they can be assimilated by fish from food (25,26).…”

“…Some resistance or restriction to transfer across the gill membrane seems to be present. Skea et al (26) has shown that the half-life of mirex in fish is very long, and Zitko and Carson (32) showed that the half-life of PBT was between 32 and 83 days for Atlantic salmon. From these observations it appears likely that the half-lives for all these compounds in fish should be long so one would expect to see slowly increasing residue concentrations in the trout over the course of the study.…”

Dioxins, PCBs, and PBDEs in Aquatic Organisms

“…In short-term aqueous toxicity tests, mirex did not cause fish mortality even at high concentrations (Tagatz et al 1975, Skea et al 1981). Mirex was not acutely toxic to fathead minnows (Pimephales promelas), and percent hatchability and growth of 30-d fry was higher in mirex-exposed Tables 2.7, 2.8, and 2.10).…”

Biomonitoring of Trace Aquatic Contaminants

“…see Branson et al, 1975;Tooby and Durbin, 1975;Niimi and Cho, 1981;Skea et al, 1981;Niimi and Oliver, 1983;Niimi and Palazzo, 1985), and these have incorporated work on a variety of compounds, including DDT, HCB, lindane (y-HCH), mirex, and PCBs. He noted that DDT was concentrated preferentially in tissues with a high lipid content, and this general rule has since been confirmed in many species from both freshwater and marine environments (see reviews by .…”
