Research ArticleOpen accessEvery word in the titleNoninvasive Environmental Monitoring of Mercury in Alaskan ReindeerLawrence K. Duffy, Richard J. Hallock, Greg Finstad, R. T. BowyerReindeer, Rangifer tarandus, are terrestrial herbivores used by Alaskan Native herders for both subsistence food and commercial export. Reindeer are a renewable resource and as part of the food system are monitored for Mercury (Hg) levels in relation to the changing Arctic environment. In this study, both free-ranging reindeer from the Seward Peninsula, Alaska, and reindeer reared at the University … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 6,738 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRemoval of Mercury from chlor-alkali Industry Wastewater using Acetobacter xylinum CelluloseA. Rezaee, J. Derayat, S. B. Mortazavi et al.In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function of pH, adsorbent dose and contact time. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 8,283 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMercury in Hair of Muskox on the Seward PeninsulaClaudia Ihl, R. Terry Bowyer, Kriya L. Dunlap, Lawrence K. DuffyProblem statement: Muskoxen (Ovibus moschatus) are distant relatives of sheep (Caprinae) and have roamed the Arctic for a million years, with populations reaching North America between 150,000 and 250,000 years ago. Muskox populations could be negatively influenced by climate change and increased exposure to contaminants. Since the snow depth is a critical factor in their ecology, effects could occur throughout … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 24 Mar 2012 · 7,005 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Frequency of Polymorphisms affecting Lead and Mercury Toxicity among Children with AutismShannon Rose, Stepan Melnyk, Alena Savenka et al.Individual risk of developmental neurotoxicity with exposure to environmentally relevant levels of lead and mercury is likely to be determined by genetic susceptibility factors as well as additive interactions with other environmental pollutants, cumulative dose, and the developmental stage of exposure. The apparent increase in autism diagnosis over the last 15 years has enhanced interest in the possibility that an … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 7,521 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetermination of Zinc, Cadmium, Lead and Copper in Kakade, Anise, Cumin, Caraway Black Pepper Extracts Using Differential Pulse Anodic Stripping Voltammetry with Hanging Mercury Drop ElectrodeZ. R. KomyAn extraction and sensitive differential pulse anodic stripping voltammetric (DPASV) method at a hanging mercury drop electrode (HMDE) is described for the determination of Zn, Cu, Pb (mg g1) and Cd (ng g1) metal ions in water and 0.1 M HCl extracts for kakade, anise, cumin, caraway and black pepper. The procedure in water extract is based on the determination … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,875 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Mercuric Ion on the Oxidant Response and Calcium Ion in the Protoplasts of Arabidopsis ThalianaJun Xing, Rui Wu, Hui Yu et al.As a non-essential element for plant growth and development, the heavy metal mercury (Hg) has significant toxicity to plants. The aim of this study was to investigate the effect of mercuric ion (Hg2+) on the oxidant response and calcium ion (Ca2+) in the protoplasts of Arabidopsis thaliana. The protoplast cells were exposed to 5.0, 10.0, and 20.0 mmol/L Hg2+ for … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 29 Aug 2023 · 4,961 accessesView PDFCite

InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to give the Red Planet its first thorough checkup since it formed 4.5 billion years ago. It is the first outer space robotic explorer to study in-depth the "inner space" of Mars: Its crust, mantle and core. … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 28 Feb 2019 · 7,229 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects of Some Heavy Metals in Some Morpho-Physiological Parameters in Maize SeedlingsSali Aliu, Bekim Gashi, Imer Rusinovci et al.Nowadays the heavy-metal pollution of the soil is causing ever greater problems, exacerbated by the fact that the heavy metals accumulated in plants may, either directly or indirectly, find their way into animals and human beings. Maize is one of the world’s most important crops, ranking third after wheat and rice, so the changes induced by one of the most … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,430 accessesView PDFCite

Approach: The efficiency of the acid activation can be described in two ways. As increase of the surface and as increase of the cumulative pore volume after the activation. Results: In different samples of the clay … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOxidative Stress in Autism: Elevated Cerebellar 3-nitrotyrosine LevelsElizabeth M. Sajdel-Sulkowska, Boguslaw Lipinski, Herb Windom et al.It has been suggested that oxidative stress and/or mercury compounds play an important role in the pathophysiology of autism. This study compared for the first time the cerebellar levels of the oxidative stress marker 3-nitrotyrosine (3-NT), mercury (Hg) and the antioxidant selenium (Se) levels between control and autistic subjects. Tissue homogenates were prepared in the presence of protease inhibitors from … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 17,119 accessesView PDFCite
