Selenium: environmental significance, pollution, and biological treatment technologies
TL;DR: There are still several challenges, particularly in achieving stringent discharge limits, the long-term stability of biogenic selenium and predicting the fate of bioreduced Selenium in the environment and biotechnological advances made in the treatment ofselenium contaminated wastewaters.

Homeostasis and toxicology of non-essential metals
TL;DR: Homeostasis and Toxicology of essential and non-essential metals are discussed in this paper, with a focus on metals that have no known nutritive function in fish at present, but which are toxic at fairly low levels, such as Ag, Al, Cd, Pb, Hg, As, Sr and U.
Journal ArticleDOI
Temporal changes in taxonomic and functional diversity of fish assemblages downstream from mountaintop mining
TL;DR: Effects of MTM were not related to physical-habitat conditions but were associated with water-quality variables, which may limit quality and availability of benthic macroinvertebrate prey.
Journal ArticleDOI
Food rationing affects dietary selenium bioaccumulation and life cycle performance in the mayfly Centroptilum triangulifer
TL;DR: The results suggest that the influence of Se on mayfly performance in nature may be tied to food resource availability and quality and nutritional status is an important consideration when applying laboratory derived estimates of toxicity to risk assessments for wild populations.
Journal ArticleDOI
Bioconcentration and biotransformation of selenite versus selenate exposed periphyton and subsequent toxicity to the Mayfly Centroptilum triangulifer.
Justin M. Conley,David H. Funk,Dean H. Hesterberg,Liang-Ching Hsu,Jinjun Kan,Yu-Ting Liu,David B. Buchwalter +6 more
TL;DR: Dissolved selenium speciation, residence time, and organisms at the base of aquatic food webs appear to be the principal determinants of Se bioaccumulation and toxicity.

TL;DR: This work identified selenoprotein genes in sequenced mammalian genomes by methods that rely on identification of selenocysteine insertion RNA structures, the coding potential of UGA codons, and the presence of cysteine-containing homologs.
Journal Article
Life-forms of phytoplankton as survival alternatives in an unstable environment
TL;DR: The best predictor of primary production and of dominant life-forms in phytoplankton is the available externat energy, on which advection and turbulence depend, and this factor overrules more detailed models using light and nutrients as most relevant parameters, and based on laboratory experiments.
Journal ArticleDOI
From selenium to selenoproteins: Synthesis, identity, and their role in human health
TL;DR: The function of most selenoproteins is currently unknown; however, thioredoxin reductases, glutathione peroxidases and thyroid hormone deiodinases are well characterised selenobroteins involved in redox regulation of intracellular signalling, redox homeostasis and thyroid hormones metabolism.
Journal ArticleDOI
PRIMARY CONSUMER δ13C AND δ15N AND THE TROPHIC POSITION OF AQUATIC CONSUMERS
TL;DR: In this paper, the variation in baseline δ15N values in 14 lakes in Ontario and Quebec was investigated and it was shown that habitat-specific variation in lake habitat can explain 72% of the variability in primary consumers δ13C.

Why Is Metal Bioaccumulation So Variable? Biodynamics as a Unifying Concept
TL;DR: It is suggested that a biologically based conceptualization, the biodynamic model, provides the necessary unification for a key aspect in risk: metal bioaccumulation (internal exposure).
