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
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
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

Cytogenetic, developmental, and biochemical effects of aluminum, iron, and their mixture in sea urchins and mussels
Springer Science and Business Media LLC - Tập 31 - Trang 466-474 - 1996
G. Pagano, E. His, R. Beiras, A. De Biase, L. G. Korkina, M. Iaccarino, R. Oral, F. Quiniou, M. Warnau, N. M. Trieff
The present study was undertaken to evaluate the toxicity of aluminum sulfate, ferric chloride and their 1:1 mixture (Mix) on early development, fertilization and offspring quality in three sea urchins species (Sphaerechinus granularis, Paracentrotus lividus, Psammechinus microtuberculatus) and in mussels (Mytilus galloprovincialis). The endpoints were the following: a) larval malformations; b) de...... hiện toàn bộ
Phân Tích Protein Học Của Mô Gan Ở Cá Dơm Cái Trưởng Thành (Danio rerio) Bị Phơi Bày Với Atrazine Dịch bởi AI
Springer Science and Business Media LLC - Tập 62 - Trang 127-134 - 2011
Yuanxiang Jin, Xiangxiang Zhang, Dezhao Lu, Zhengwei Fu
Atrazine (ATZ), herbicide phổ biến nhất, là một chất ô nhiễm thường gặp trong các hệ sinh thái nước ngọt. Trong nghiên cứu này, phương pháp điện di gel hai chiều và khối phổ tách lớp laser hỗ trợ ma trận, kết hợp với phân tích mô bệnh lý, đã được sử dụng để phát hiện tổn thương gan ở cá dơm cái trưởng thành (Danio rerio) khi tiếp xúc với ATZ. Hơn 600 điểm protein gan đã được phát hiện trong mỗi ge...... hiện toàn bộ
