Metal Bioaccumulation by the Neotropical Clam Anomalocardia flexuosa to Estimate the Quality of Estuarine Sediments
(2021-01-01)
This investigation evaluated the bioaccumulation potential of the tropical estuarine bivalve Anomalocardia flexuosa for trace metals. To this aim, chemical and sedimentological analyses and bioaccumulation tests were ...
Bioaccumulation of some trace elements in the biota of the hydrothermal fields of the Guaymas Basin (Gulf of California)
(Boletín de la Sociedad Geológica Mexicana, 2009)
Data from the hydrothermally influenced Guaymas Basin of the Gulf of California are presented on the concentration and distribution of Ag, As, Au, Ba, Cd, Co, Cr, Cu, Fe, Hg, Mn, Pb, Sb, Se, and Zn in different tissues of ...
Bioaccumulation kinetics of copper in Ruditapes philippinarum exposed to increasing, continuous and pulsed exposure: Implications for growth
(2017-10-01)
Metal bioaccumulation and toxicity to aquatic organisms depends on factors such as magnitude, duration and frequency of the exposure. The type of the exposure affects the toxicokinetic processes in the organisms. In this ...
Bioaccumulation and acute toxicity of As(III) and As(V) in Nile tilapia (Oreochromis niloticus)
(2019-02-01)
The distribution of arsenic in the different tissues of tilapia fish is determined by the exposure time and the depuration rate. The mechanisms of toxicity/carcinogenicity depend on the arsenic species involved in the ...
Fertility and Iron Bioaccumulation in Drosophila melanogaster Fed with Magnetite Nanoparticles Using a Validated Method
(Molecular Diversity Preservation International, 2021-05-10)
Research on nanomaterial exposure-related health risks is still quite limited; this includes standardizing methods for measuring metals in living organisms. Thus, this study validated an atomic absorption spectrophotometry ...
The microbial mercury link in oligotrophic lakes: Bioaccumulation by picocyanobacteria in natural gradients of dissolved organic matter
(Pergamon-Elsevier Science Ltd, 2019-09)
Andean Patagonian lakes are oligotrophic systems characterized by low dissolved organic carbon (DOC) levels and moderate to high Hg concentration that determine naturally high Hg/DOC ratios and bioavailability. In these ...
Differential bioaccumulation and translocation patterns in three mangrove plants experimentally exposed to iron. Consequences for environmental sensing
(2016-08-01)
Avicennia schaueriana, Laguncularia racemosa and Rhizophora mangle were experimentally exposed to increasing levels of iron (0, 10, 20 and 100 mg L-1 added Fe(II) in Hoagland's nutritive medium). The uptake and translocation ...
Bioaccumulation of 10 trace elements in juvenile fishes of the lower Paraná River, Argentina: implications associated with essential fish growing habitat
(Springer Heidelberg, 2020-08)
This study assessed the concentration, bioconcentration, and bioaccumulation of As, Cd, Co, Cr, Cu, Mg, Mn, Ni, Pb, and Zn in juvenile fishes (Acestrorynchus pantaneiro, Brycon orbygnianus, Cyphocharax voga, Megaleporinus ...
Bioaccumulation of mercury in muscle tissue of Yellowfin Tuna, Thunnus albacares, of the eastern Pacific Ocean
(Biological Trace Element Research, 2011)
Tuna, like most large pelagic fish, are highly exploited by man, and it is, therefore, important to determine mercury (Hg) levels in these species in order to estbaliz allowable limits for their consumption and/or contamination ...
