Bioaccumulation in freshwater crabs, Endosulfan accumulation in different tissues of Zilchiopsis collastinensis P. (Decapoda: Trichodactylidae)
(Springer, 2012-11)
We examined the bioaccumulation of α- and β-endosulfan and endosulfan sulfate in tissues from the crab Zilchiopsis collastinensis. There was more endosulfan accumulated in the hepatopancreas (from <2 to 467.8 ng g-1) than ...
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 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 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 ...
Metals concentration and bioaccumulation in the marine-coastal trophic web from Buenos Aires province southern coast, Argentina
(Taylor & Francis Ltd, 2019-07-25)
Metals accumulated in the tissues of organisms inhabiting marine ecosystems generally reflect their bioavailable levels within that environment. The aim of this work was to study the presence and concentration of metals ...
UV radiation effects and bioaccumulation of UV-absorbing compounds in Artemia persimilis larvae
(PanamJas, 2016-07)
The aims of this study were to determine if larvae of Artemia persimilis (Crustacea: Branchiopoda) can bioaccumulate ultraviolet radiation (UVR) absorbing compounds like mycosporine-like aminoacids (MAAs) through the diet ...
Atrazine uptake, translocation, bioaccumulation and biodegradation in cattail (Typha latifolia) as a function of exposure time
(Elsevier, 2021-08-30)
The extensive use and environmental persistence of atrazine has resulted in its ubiquitous occurrence in water resources. Some reports have described atrazine bioaccumulation and biodegradation pathways in terrestrial ...
Heavy Metal Bioaccumulation by Cestode Parasites of Mustelus Schmitti (Chondrichthyes: Carcharhiniformes), from the Bahía Blanca Estuary, Argentina
(Juniper Publishers, 2019-08)
The environment of the Bahía Blanca estuary is considered a hot spot in terms of pollution. Bioindicators should have the ability to react relatively fast to certain pollutants and environmental disturbances. Therefore, ...
