Bioremediation of Pcb Contaminated Surface Soil: A Microcosm Study
… VA). In this study, degradability of PCBs (Aroclor 1242) from an aged surface soil was evaluated using serum bottle microcosms containing aceticlastic methanogenic consortium, enriched from a municipal anaerobic digester. Two different experiments, "intermediate feed" and "starve and feed" …

Polychlorinated biphenyl effects on avian hepatic enzyme induction and thyroid function
… (Coturnix japonica). Then UDP-GT induction by Aroclor 1254 was evaluated in quail, and quail and mice were compared in their responses to Aroclor 1254. In Experiment 1, Japanese quail and Balb/c mice were dosed orally with vehicle or Aroclor 1254 (250 or 500 mg/kg) and sacrificed five days …

Hepatic CYP1A enzymes in fish as a biomarker of water pollution
… towers and a holding tank. Fish received BNF and Aroclor via IP injection and diets. The IP doses for BNF and Aroclor were 13 and 120 mg/kg body weight, respectively. Fish were sacrificed 4 and 7 days post injection. P450 content, AHH and EROD activities were significantly higher in BNF and …

Xenobiotic monooxygenase activity and the response to inducers of cytochrome P-450 during embryonic and larval development in fish
… was inducible in Fundulus embryos by both Aroclor 1254 and No.2 Fuel oii. Embryos were competent to respond to induction as early as 4 days from fertilization. In Fundulus eleutheroembryos, Aroclor 1254 induced BPM activity in both the liver and extrahepatic tissues. Aminopyrine …

Sediment toxicity and bioaccumulation of toxicants in the zebra mussel, Dreissena polymorpha, at Times Beach, Buffalo, New York
… as 549 mg/kg for total PAHs, 9 mg/kg for PCB Aroclor 1248, and 54, 99, 6, 355, 637, and 16 mg/kg for the metals: As, Ba, Cd, Cr, Pb, and Hg respectively. To predict contaminant bioavailability, elutriate and whole sediment toxicity tests were performed utilizing the cladoceran, <i>Daphnia …

Sport fish consumption advisory for West Virginia
… and analyzed for total mercury concentration and Aroclors (PCBs). Recommended meal frequencies were calculated from contaminant levels and based on the Guide. Mean fillet sample contaminant levels were compared to composite sample levels and found to require the same level or in one case a more …

The Effects of Two Polychlorinated Biphenyl Mixtures on Honey Bee (Apis Mellifera) Foraging Behavior and Hypopharyngeal Gland Development
… focused on the effects of two PCB mixtures, Aroclor 1242 and 1254, on the European honey bee, Apis mellifera, as there is evidence that these compounds disrupt hormonal function in endocrine systems of mammals. After testing the dose range 0--80 mug/bee of A1242 and 0--1000 mug/bee of A1254, …

Applications of aerobic and anaerobic bacteria in the fields of biological degradation of contaminants and biological wastewater treatment
… of Carbon- and Energy-sources. Beside DDE, Aroclor 1260, and a mix of four pure PCB-Congeneres (one Tetra-, one Hexa, one Hepta- and one Deca-Chlorobiphenyl) were used to test for the reductive dechlorination. The cultivation process of the baceria lasted six months. Samples of the cultures …

Xenobiotic metabolism and zebrafish (danio rerio) larvae
… identified genes was modulated upon exposure to Aroclor 1254, and the metabolic activities towards ethoxy-resorufin, 7-ethoxy-coumarin and octyloxymethylresorufin were observed to be inducible by exposure to in vitro inhibitors of CYP activities. Wik strain zebrafish larvae (72 hpf) were also …

Metabolic Factors Determining Outcome in Chemotherapy: Studies with Pazopanib
… reduced in animals which has been induced using Aroclor-1254, which suggests that induction of the cytochrome P450 system does induce the turnover of pazopanib thereby reducing bioavailability and efficacy in vivo. <br/> <br/>

Field and Greenhouse Studies of Phytoremediation with California Native Plants for Soil Contaminated with Petroleum Hydrocarbons, PAHs, PCBs, Chlorinated Dioxins/Furans, and Heavy Metals
… for. The average PCB concentration (measured as Aroclor 1260) reductions in soils with Purple Needlegrass and chelated Coyote Brush were 49.4% and 51.4% respectively (p < 0.05). However, the sterilized unplanted control also had a decrease of Aroclor 1260 concentrations in the soil of 36.6% (p < …

Effects of a polychlorinated biphenyl in mice caged at different densities and fed at different nutritional levels
… assess the physiological effects of dietary PCB (Aroclor 1254) ingestion in white mice (Mus musculus) and in laboratory-reared white-footed mice (Peromyscus leucopus), and to determine if these effects were aggravated by group-caging or feed restriction. The underlying hypothesis was that PCBs may …

Effects of Polychlorinated Biphhenyls in the Ring-Necked Pheasant
… 0 and 25 mg polychlorinated biphenyls (PCB), Aroclor 1254, and hens were given O, 12.5, and 50 mg. Egg production was reduced (P<0.01) in the hens given 50 mg PCB both years. Fertility, determined by visual inspection of incubated eggs, was unaffected by PCB. Hatchability was lowest in the …

Molecular regulation of the induction of cytochrome P-450E in the estuarine fish Fundulus heteroclitus
… induced by 3,4,5,3',4',5'hexachlorobiphenyl and Aroclor treatment and the P-450E orthologue in teleost species including rainbow and brook trout, winter flounder, and Fundulus. P-450E was induced in these fish by BNF and other xenobiotics. P-450E protein content in all fish analyzed correlated …
