Genotoxicity studies on toxic metals and their organic compounds are very important, especially so in the investigation of effects these aquatic environments where they tend to accumulate. The use endemic organisms as biological sentinels has proved useful environmental monitoring. We assessed mutagenic potential tributyltin (TBT) inorganic lead (PbII) using samples fish Hoplias malabaricus (commonly called traíra) comet assay piscine micronucleus chromosome aberration tests. Eighteen H....
Abstract The toxicity of titanium dioxide nanoparticles (TiO 2 ‐NP) in the blood, liver, muscle, and brain a Neotropical detritivorous fish, Prochilodus lineatus , was tested. Juvenile fish were exposed to 0, 1, 5, 10, 50 mg L −1 TiO ‐NP for 48 hours (acute exposure) or 14 days (subchronic evaluate changes hematology, red blood cell (RBC) genotoxicity/mutagenicity, liver function (reactive oxygen species (ROS) production, antioxidant responses, detoxification, histopathology),...
The effects of clastogenic or mutagenic agents have rarely been studied in neotropical fish species exposed to contaminated water. In this study, the genetic damage caused by lead widely distributed South American fish, Hoplias malabaricus, was assessed using comet (SCGE) assay and testing for chromosomal aberrations. Eighteen specimens were acclimatized laboratory conditions then chronically food feeding prey (Cyprinus sp.) injected intraperitoneally with doses inorganic adjusted give a...
Abstract Over the last two decades, several classification changes were proposed for family Loricariidae and their phylogenetic relationships could be only partly resolved so far. Two major problematic groups are subfamilies Hypoptopomatinae Neoplecostominae. Therefore, we analysed four species of this family, being three Neoplecostominae (Neoplecostomus yapo, Kronichthys lacerta Isbrueckerichthys duseni), one representative (Parotocinclus maculicauda), in order to compare chromosomal data...
