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 ...
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 ...
Biomarkers and heavy metal bioaccumulation in mussels transplanted to coastal waters of the Beagle Channel
(Elsevier Inc, 2010-03)
Mussels coming from a mussel farm at Brown Bay (Beagle Channel) were transplanted to four sites inside Ushuaia Bay for 2 and 4 weeks. The objective of this study was to assess the quality of coastal waters of Ushuaia Bay ...
Metal contamination in threatened elasmobranchs from an impacted urban coast
(Elsevier B.V., 2021-02-25)
Guitarfishes and angelsharks are two of the most endangered elasmobranch groups. Despite this, limited knowledge exists regarding the effects of environmental contamination in these groups. For this reason, this study ...
Elementos traço e parasitismo em tilápia do nilo cultivada no sul do Brasil
(2016-01-01)
This study evaluated the trace elements and parasitological indices in Nile tilapia examined from two different facilities, named as swine-consorted, using pig manure, and monoculture. For trace element analysis, the fish ...
Acúmulo, distribuição e eliminação de ferro em três espécies vegetais do manguezal
(Universidade Estadual Paulista (Unesp), 2016-02-26)
A poluição por metais tem sido um dos principais problemas ambientais, tendo em vista a sua toxicidade, persistência no ambiente e bioacumulação. Os manguezais frequentemente são expostos a esses contaminantes, sendo o ...
High bioaccumulation of cadmium and other metals in Patagonian edible gastropods
(Taylor & Francis As, 2017-06-08)
High concentrations of metals are accumulated by edible marine resources, affecting human health. Marine gastropods have been commercially captured and consumed in Argentina for decades without official regulations or ...
Bioaccumulation of heavy metals in mesozooplankton from a human-impacted south western Atlantic estuary (Argentina)
(Sears Foundation Marine Research, 2019-01-01)
The total metal concentrations (Cd, Cu, Pb, Zn, Mn, Ni, Cr, and Fe) in the mesozooplankton (200 μm–2 mm) were studied for a year in a human-impacted estuary strongly affected by urban and industrial discharges located in ...
Biosynthesis of iron oxide nanoparticles from mineral coal tailings in a stirred tank reactor
(Gamini Senanayake, 2019-01-23)
Chemical oxidation of mineral coal tailings is one of the most important environmental issues during the lifetime of a mine. The presence of sulfur compounds favors the occurrence of metal acid leaching, which contaminates ...
Avaliação de bioacumulação de chumbo e sua influência sobre o crescimento em alevinos de tilápia do Nilo
(Universidade Tecnológica Federal do ParanáApucaranaBrasilLicenciatura em QuímicaUTFPR, 2017-08-14)
Humans, animals and plants can be exposed to metal contamination all the time due to anthropogenic activities. In this work, the influence of lead on Nile tilapia was studied to evaluate the development and growth of the ...
