Bioaccumulation of metals in aquatic insects of streams located in areas with sugar cane cultivation
(Sociedade Brasileira de Química, 2010)
Streams located in areas of sugar cane cultivation receive elevated concentrations of metal ions from soils of adjacent areas. The accumulation of metals in the sediments results in environmental problems and leads to ...
Bioaccumulation of metals in aquatic insects of streams located in areas with sugar cane cultivation
(Sociedade Brasileira de Química, 2010-01-01)
Streams located in areas of sugar cane cultivation receive elevated concentrations of metal ions from soils of adjacent areas. The accumulation of metals in the sediments results in environmental problems and leads to ...
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 ...
Implications on the Pb bioaccumulation and metallothionein levels due to dietary and waterborne exposures: The Callinectes danae case
(2018-10-30)
This study aimed to assess the bioaccumulation of Pb and induction of metallothionein-like proteins (MT) in Callinectes danae through single and combined dietary and waterborne exposures. Male C. danae individuals were ...
Redox dysregulation and bioaccumulation of copper in tilapia Oreocromis niloticus
(Wiley-Blackwell, 2014-03-01)
The objective of this study was to evaluate the effect of two concentrations of copper (0.13 and 0.5mgL(-1)) on juveniles of tilapia, Oreocromis niloticus (Linnaeus), using two toxicological assays (I- copper exposure and ...
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 ...
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 ...
Kinetics of bioaccumulation of heavy metals in Odontesthes bonariensis is explained by a single and common mechanism
(Elsevier Science, 2014-02-24)
Fish are often considered a very sensitive indicator of heavy metal contamination in aquatic ecosystems; however, the detailed mechanisms of bioaccumulation remain unclear. Here, we study the bioaccumulation processes of ...
Bioaccumulation of potentially toxic trace elements in benthic organisms of Admiralty Bay (King George Island, Antarctica)
(Londres, 2013)
Data about the concentration, accumulation and transfer of potentially toxic elements in Antarctic marine food webs are essential for understanding the impacts of these elements, and for monitoring the pollution contribution ...
Bioaccumulation of potentially toxic trace elements in benthic organisms of Admiralty Bay (King George Island, Antarctica)
(Bethesda, 2014)
Data about the concentration, accumulation and transfer of potentially toxic elements in Antarctic marine food webs are essential for understanding the impacts of these elements, and for monitoring the pollution contribution ...
