Sorting the main bottlenecks to use paper-based microbial fuel cells as convenient and practical analytical devices for environmental toxicity testing
(Elsevier, 2021-02)
Three of the primary bottlenecks, which should be consider for practical, point-of-need use of microbial fuel cell (MFC) analytical devices were surpassed in this work: i) the use of a diffusive barrier, hence, an electrogenic ...
Application of two bioassays as potential indicators of phenol phytoremediation efficiency by tobacco hairy roots
(Taylor & Francis Ltd, 2019-08)
Phenol is one of the contaminants most frequently found in the environment and it is considered a priority pollutant due to their toxic effects. Hairy roots (HR) constitute a good model tool for the removal of this ...
Abatement of toxicity of effluents containing Cr(VI) by heterogeneous photocatalysis. Toxicity assessment by AMPHITOX assay
(Academic Press Inc Elsevier Science, 2015-09)
Toxicity of a Cr(VI) solution before and after treatment by TiO2 heterogeneous photocatalysis (HP) was performed with AMPHITOX bioassay. Changes in toxicity on Rhinella arenarum larvae for 10-d were monitored after exposure ...
Toxicity and bioavailability of mercury in spiked sediments on Hyalella curvispina Shoemaker, 1942

Joint toxicity of copper and diazinon during embryonic and larval development of the common South American toad, Rhinella arenarum
(Taylor & Francis Ltd, 2016-06)
Copper (Cu) and diazinon are two widely distributed pollutants; they coexist in agro-ecosystems and cause toxicity to wild biota. This study proposes to analyse the joint toxicity of binary mixtures of Cu and diazinon on ...
Toxic effects of lemon peel constituents on Ceratitis capitata
(Springer, 2004-02)
A series of experiments were conducted to evaluate the toxicity of lemon peel extracts incorporated into mediterranean fruit fly Ceratitis capitata diet. Extracts were obtained with different solvents: diethyl ether, ethyl ...
Combined endosulfan and cypermethrin-induced toxicity to embryo-larval development of Rhinella arenarum
(Taylor & Francis, 2016-02)
The combined effects of two widely used pesticides, endosulfan and cypermethrin, on survival of embryo–larval development of the South American toad (Rhinella arenarum) were examined. The toxicity bioassays were performed ...
Assessment of polyaniline nanoparticles toxicity and teratogenicity in aquatic environment using Rhinella arenarum model
(Academic Press Inc Elsevier Science, 2015-04)
With the rapid growth of nanotechnology and the applications of nanoparticles, environmental exposure to these particles is increasing. However, their impact in human and environmental health is not well studied. Anurans, ...
Toxicity, freezing and cold storage tests of native species semenTestes de Toxicidade, congelamento e refrigeração em sêmen de espécie nativa
(Inst Pesca, 2017-09)
In the first part of this study, toxicity tests were performed on the sperm of Macrobrachiumacanthurus using four cryoprotectants for periods of 10 and 20 min at concentrations of 10 and 20%.In the second part, cryopreservation ...
