Effects of various kitchen heat treatments, ultraviolet light, and gamma irradiation on mirex insecticide residues in fish
Concentrations of the chlorinated hydrocarbon insecticide mirex (C/sub 10/Cl/sub 12/) were determined in brown trout from a defined contaminated area of Spring Creek, Centre County, PA, using electron-capture gas chromatography. Conventional heat treatments, namely, baking, frying, poaching, and baking without skin, did not cause significant decreases of the contaminant. Ultraviolet irradiation led to significant reductions (p < 0.05) in mirex concentration in muscle tissue. Exposures of 24, 48, and 72 hr led to degradations of 30.0%, and 45.6%, respectively, of the initial mirex concentration. Gamma irradiation also led to significant reductions (p < 0.05) in mirex concentration in muscle tissue. Following absorption of 1, 3, and 5 Mrad, degradations of 9.8%, 23,1%, and 37.5%, respectively, of the initial mirex concentration were observed.
