Although this study demonstrated a high diversity of the microorganisms present, only a few have been shown to be opportunistically pathogenic to humans and none of these organisms described have been described previously as having an inhalational route of infection and therefore we do not believe that the species of organisms identified pose a significant health and safety threat for immunocompetant individuals. Metal gill binding and toxicity can be modeled using the concentration addition model, in which the toxic unit (TU) concept is used to determine if constituent metals are acting in a strictly additive, less than, or greater than additive fashion. Enhanced Pb sensitivity (e.g., decrease LC50) in both types of C. elegans was observed with both increased and decreased temperatures when compared to that at 20°C. The purpose of this study was to investigate the impact of oil pollution in a desert location (the Greater Al-Burgan oil fields, an area damaged in the Gulf War in 1991) in Kuwait on the hepatotoxicity of the Sand lizard Acanthodactylus scutellatus (A. scutellatus). Developing Xenopus laevis were exposed from 2- to 5-d postfertilization (pf) to 0.1 or 1 mg/l of Aroclor 1254. The aims of this study were to determine the sorption coefficient (LogK(DOC)) of 17β-estradiol (E2), according to the size and composition of dissolved organic matter (DOM) isolated from wastewater effluent using a fluorescence quenching (FQ) method, and to measure the estrogenic changes due to the extent of E2 sorption onto effluent DOM (EfOM) by using an E-screen bioassay. About. These findings indicate that in ewes, exposure of the brain to more highly chlorinated, ortho-substituted PCBs may be modulated by photoperiod. Similar to BNF, organisms treated with clotrimazole (CTZ), a CYP450 inhibitor, resulted in increased toxicity and TNT metabolism. A standardized bioassay previously developed with ivermectin for the yellow dung fly (Scathophagidae) and the face fly (Muscidae) was applied to test the response of 11 dung fly species to the presumably less toxic parasiticide moxidectin. This study confirmed that the prolonged exposure to oil pollution may result in increased accumulation of contaminants and may cause severe liver pathology in a range of wild organisms such as A. scutellatus. OMR test was used to detect the visual behavior. This study was designed to experimentally measure the assimilation efficiency of hexachlorobenzene (HCB) in a warm-water, benthic-feeding fish species, the channel catfish (Ictalurus punctatus). Composted products derived from animal sources are further required by EU biohazard safety regulatory legislation that such composts either attain 70 degrees C for over 3h during maturation or via treatment at 70 degrees C for 1h before being considered for dispensation on land. 6.2 CiteScore. Data provided are for informational purposes only. Histological changes, seen in the kidney of mothers and their pups treated with 2,4-D are characterized by a narrowed Bowman's space, tubular epithelial cells degeneration, widened tubular lumen and vascular congestion. Our practical understanding must evolve accordingly to maintain an acceptable quality of life. Treatment of organisms with beta-napthoflavone (BNF), a CYP450 inducer, increased the toxicity of TNT and increased the rate of elimination and metabolism of TNT. This work aimed to quantify biochemical responses of ecological importance in H. curvispina males under stress exposure to sublethal concentrations of waterborne copper (Cu) and cadmium (Cd); in order to obtain basic physiological data as indicators of early effect on this species, on track to its standardization. Standard Journal Abbreviation (ISO4) - Ecotoxicology and Environmental Safety The Standard Abbreviation (ISO4) of Ecotoxicology and Environmental Safety is “Ecotoxicol. Submit your article Guide for Authors. Twenty sections (10 from males and 10 from females) from each tar mat (polluted) and control sites were prepared and examined for cell diameter and nuclear measurements using Cell Analysis Systems. In addition, the expression of SWS2 was significantly down-regulated in all PCB1254 treatment groups (P<0.05), whereas the decreased expression of the CRX, RHO and SWS1 was found in the 0.5 and 1mg/L PCB1254 groups (P<0.05). The exposed groups have shown significant variations in frequencies of MN and altered erythrocytes in comparison to control group, and these frequencies increased significantly (p<0.05) with the increase of carbofuran concentration. The bioassay was carried out under different experimental conditions, simulating local (natural soil) vs. control conditions (LUFA soil), and irrigation with artificial rainwater vs. irrigation with diluted acidic effluent. Nevertheless, despite the overall lack of responsiveness of the epigeic arthropod community data, a few taxa were negatively correlated with metal concentrations (Clubionidae and Staphylinidae), while Pseudoscorpionida were associated with the toxicological profile of the sites.

Low waterborne copper exposure (around 10(-10)molL(-1) free Cu(2+) ions) was kept in the experiments. Unlike information previously collected in the chemical and ecotoxicological lines of evidence, we found no clear evidence of impacts of soil contamination on the edaphic arthropod assemblage. Adult estuarine dwelling gastropods Nassarius burchardi and Nassarius jonasii were exposed to the synthetic estrogen 17α-ethynylestradiol (EE2) to determine the effects on the development and survival of their offspring. Taguchi model showed that experimental and predicted values were closer to each other demonstrating the success of Taguchi approach. A total of 16 bacterial genera were identified including both Gram-positive and Gram-negative genera. No significant difference (p>0.05) was observed between the control and the treatment groups of mudskipper erythrocyte exposed to field concentrations. The results showed that by exposure of cladocerans during 7 days to contaminated food with 68 fg Cu cell(-1), a significant reduction in neonate production, survival and body size were obtained. In addition, a significant decline in kidney glutathione, non-protein thiol and vitamin C levels was also observed. Given the consistency of the chemical and ecotoxicological lines of evidence, we must conclude that the litter arthropod assemblage underestimated the impacts of contamination in this abandoned mining area.

No detectable metabolism of HCB by catfish was found. Multivariate analyses were unable to extract relevant environmental gradients related to contamination, as most of the sites shared the same taxa overall. Articles & Issues. Ecotoxicology and Environmental Safety is a multi-disciplinary journal that focuses on understanding the exposure and effects of environmental contamination on organisms including human health. Over the last decades, amphibians decline has been reported worldwide. Publish. On the other hand, a significant decline of EROD and MROD activities was observed in vivo. Inhibition on egg production of zooplankton at 38 fg Cu cell(-1) were observed in 36 days chronic dietary copper exposure. Acute mortality estimates (48h) were developed followed by population-level studies after chronic exposure. Concentrations of two PCBs (PCB28 and PCB153) in the plasma and four PCBs in the CSF (PCB101, PCB138, PCB153, and PCB180) were significantly higher during LD than SD. Articles & Issues. 4.872 Impact Factor. Copyright © 2015 The Authors. Stringent measures are further required by law for composted products arising from rural industrialists producing pelleted fertilizers from re-composted animal agriculture wastes comprising pig slurry solids, poultry litter and spent mushroom compost, which carry residual food-borne pathogens with implications to the food chain including humans. Ecotoxicology and Environmental Safety. Published by Elsevier Inc. All rights reserved. Two months given for revision. Gram-negative organisms accounted for only 4/38 (10.5%) bacterial isolates and included the following genera, Brevundimonas, Lysobacter, Psychrobacter and Rhizobium. A laboratory experiment found that purified Bt toxins Cry1Ab and Cry1Ac had no toxic effect on D. hyalina even in the treatment in which the Bt toxin concentration was as high as 2500ng/ml. Articles & Issues. The testing was continued using the concentrations of 12.5 and 25 microg/L. Sign in to set up alerts . The determination of the growth of examined photoautotrophs was performed by time-course measurements of total chlorophyll content in experimental cultures. exhibited high concentrations of Cd, which was attributed to the influence of the natural upwelling processes which occur annually in that geographical region. In all the field investigations, only one significant difference was found on copepods in the tillering stage of 2009, but the difference was not related to the presence of the Cry toxin. Search in this journal. Additional examined endpoints included time course of toxicity at LC50s, pharyngeal pumping, reproduction, life span, and Hsp90 expression. Press-sieving sediment did not reduce the variability in the toxicity data and also contributed uncertainty to the chemistry data. The most remarkable feature observed in hepatocytes of lizards collected from the tar mat sites were swelling of hepatocytes, ballooning degeneration of hepatic cytoplasm and cell death. Search in this journal. Therefore, current results present a clear evidence of the response of C. gariepinus to carbofuran and allow us to consider that C. gariepinus as a good bioindicator to reflect the toxicity and the genotoxic potential of carbofuran that might be released into the aquatic ecosystems. This journal is a peer reviewed, open access journal. Energy metabolism was similarly affected both by exposure to Cu and exposure to Cd.
