Natural toxicants in human foods: psoralens in raw and cooked parsnip root.
Parsnip root contains three photoactive, mutagenic, and photocarcinogenic psoralens in a total concentration of about 40 parts per million. These chemicals are not destroyed by normal cookingExpand
Chlorpyrifos and 3,5,6-trichloro-2-pyridinol: residues in the body tissues of cattle wearing chlorpyrifos-impregnated plastic ear bands.
Residues of the insecticide chlorpyrifos and its metabolite 3,5,6-trichloto-2-pyridinol (pyridinol) were determined in the body tissues of Hereford yearlings at intervals after they had a 10%Expand
Chlorpyrifos and 3,5,6-trichloro-2-pyridinol: residues in body tissues of swine treated with chlorpyrifos for hog louse and itch mite control.
Residues of chlorpyrifos and pyridinol were determined in abdominal fat, muscle, liver, and kidney tissues of swine at weekly intervals after they had been treated with “Dursban® 44 Insecticide Formulation” for control of the hog louse and the itch mite. Expand
Residues in milk resulting from ultra-low-volume sprays of Malathion, Methoxychlor, Coumaphos, Ronnel, or Gardona for control of the horn fly.
No residues were found in samples of milk from dairy Cows treated twice daily for 21 days with I ml of a mist spray of either of 2 concentrations of malathion, coumaphos, or Gardona®Expand
Residues of Gardona in the body tissues and eggs of laying hens exposed to treated litter and dust boxes for control of external arthropod parasites.
Gardona® (2-chloro-1-(2,4,5-trichlorophenyl) vinyl dimethyl phosphate) placed in dust-bath boxes and in floor litter in chicken houses for 4 weeks produced maximum residues of 0.058 ppm in the backExpand
Famphur and its oxygen analogue: residues in the body tissues of reindeer.
At 24 h after reindeer received a single intramuscular injection of famphur, residues were found preponderantly in fatty tissue, except for the injection-site muscle, which demonstrates the difficulty of analyzing the true injection site. Expand
