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 ...
Bioaccumulation of metals in aquatic insects of streams located in areas with sugar cane cultivation
(Sociedade Brasileira de Química, 2014)
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 and glutathione S-transferase activity on Rhinella arenarum tadpoles after short-term exposure to antiretrovirals
(Pergamon-Elsevier Science Ltd, 2020-05)
The aim of the present study was to investigate the bioaccumulation and toxicological effects of four antiretrovirals (lamivudine, stavudine, zidovudine and nevirapine) on Rhinella arenarum tadpoles, after short-term (48 ...
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 ...
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 ...
