Environmental Effects of Heavy Spillage from a Destroyed Pesticide Store near Hargeisa (Somaliland) Assessed During the Dry Season, Using Reptiles and Amphibians as Bioindicators
Springer Science and Business Media LLC - Tập 32 - Trang 80 -93 - 1997
M. R. K. Lambert
A pesticide store near Hargeisa (Somaliland) was damaged by bombing in May 1988, and subsequently looted by local people, who removed and drained drums of chemicals. Assessment of the effects of resultant spillage during the dry season, March/April 1993, established that pesticides, mainly organochlorines (dieldrin and products and BHC isomers) and organophosphates (fenitrothion and malathi...... hiện toàn bộ
Polycyclic Aromatic Hydrocarbon Contamination in South Carolina Salt Marsh-Tidal Creek Systems: Relationships Among Sediments, Biota, and Watershed Land Use
Springer Science and Business Media LLC - Tập 57 - Trang 103-115 - 2008
Thomas R. Garner, John E. Weinstein, Denise M. Sanger
Sediments and biota from 11 tidal creeks were sampled and classified into forested, suburban, and urban/industrial watershed land-use categories. Total PAH levels (∑PAH16) in sediments were significantly higher in urban/industrialized creeks (5,795 ± 1,173 ng/g) compared to suburban (793 ± 131 ng/g) and forested (238 ± 34 ng/g) creeks. No differences in ∑PAH16 levels among land-use classifications...... hiện toàn bộ

Influence of age on the relative sensitivity of Hyalella azteca to diazinon, alkylphenol ethoxylates, copper, cadmium, and zinc
Springer Science and Business Media LLC - Tập 26 - Trang 110-113 - 1994
S. A. Collyard, G. T. Ankley, R. A. Hoke, T. Goldenstein
Laboratories testing Hyalella azteca use a wide range of ages (or sizes) of the amphipod in their studies. The objective of this study was to investigate age-specific differences in sensitivity of the amphipod to contaminants with varying toxic modes of action. Hyalella azteca, ranging in age from <1 to 26 d, were tested in 96-h water-only exposures with the organophosphate pesticide diazinon, a m...... hiện toàn bộ

Bioremediation of Tetrachloroethylene-Contaminated Groundwater in a Model Aquifer: Effects on Green Frogs (Rana clamitans) and Xenopus laevis as Potential Wetland Receptors
Springer Science and Business Media LLC - Tập 52 - Trang 410-417 - 2007
Tana V. McDaniel, Nathalie Ross, Pamela A. Martin, Helena Steer, Ann-Marie Irwin Abbey, Suzanne Lesage
Recent regulations require that the ecological effects of microorganisms introduced into the environment, such as for groundwater bioremediation, be assessed prior to their utilization. A native anuran (Rana clamitans) and a model anuran (Xenopus laevis) were used as potential wetland receptors of tetrachloroethylene (PCE)-contaminated groundwater, undergoing three bioremediation treatments: natur...... hiện toàn bộ
An Ecologically Framed Mercury Survey of Finfish of the Lower Chesapeake Bay
Springer Science and Business Media LLC - Tập 65 - Trang 510-520 - 2013
Xiaoyu Xu, Michael C. Newman, Mary C. Fabrizio, Lian Liang
Total mercury (THg) and methylmercury (MHg) concentrations and determents of mercury (Hg) accumulation were examined for muscle tissues of 10 finfish from the lower Chesapeake Bay (LCB) and its tributaries. There was no suggestion of potential human harm from Hg due to LCB fish consumption: None of the sampled fish had THg concentrations approaching the United States Environmental Protection Agenc...... hiện toàn bộ
Evaluation of Stage-Dependent Genotoxic Effect of Roundup® (Glyphosate) on Caiman latirostris Embryos
Springer Science and Business Media LLC - Tập 72 - Trang 50-57 - 2016
Pamela Mariana Burella, Maria Fernanda Simoniello, Gisela Laura Poletta
The agricultural expansion over the past decades, along with the associated increase in the use of pesticides, represents a high risk for many wild species. Caiman latirostris is a South American caiman with many features that make it highly vulnerable to pesticide exposure. Considering previous finding on the genotoxicity of the glyphosate-based formulation Roundup® in this species, the aim of th...... hiện toàn bộ
Fate and effects of the insecticide Dursban® 4E in indoor Elodea-dominated and macrophyte-free freshwater model ecosystems: III. Aspects of ecosystem functioning
Springer Science and Business Media LLC - Tập 25 - Trang 160-169 - 1993
T. C. M. Brock, J. J. R. M. Vet, M. J. J. Kerkhofs, J. Lijzen, W. J. van Zuilekom, R. Gijlstra
The effects of the insecticide Dursban® 4E (active ingredient chlorpyrifos) on aspects of water chemistry, community metabolism, and decomposition of particulate organic matter were studied in indoor freshwater microcosms intended to mimic drainage ditches. To several of these systems, a single dose (simulating aerial drift) was applied to achieve nominal chlorpyrifos concentrations of 5 or 35 μg/...... hiện toàn bộ
Honey Bees as Indicators of Radionuclide Contamination: Comparative Studies of Contaminant Levels in Forager and Nurse Bees and in the Flowers of Three Plant Species
Springer Science and Business Media LLC - Tập 35 - Trang 287-294 - 1998
T. K. Haarmann
Two separate field experiments were conducted as part of ongoing research concerning the use of honey bees (Apis mellifera) as indicators of environmental radionuclide contamination. The experiments were conducted in a study site containing radionuclide contamination above background levels. The first experiment compared levels of radionuclides found in forager bees to levels found in nurse bees...... hiện toàn bộ
