Reactive oxygen species (ROS) are an unenviable part of aerobic life. Their steady-state
concentration is a balance between production and elimination providing certain steady …

The presence of reactive oxygen species (ROS) in living organisms was described more
than 60 years ago and virtually immediately it was suggested that ROS were involved in …

Selenium (Se) is an essential trace-element that becomes toxic when present at high
concentrations for aquatic organisms. The knowledge about the mechanism of Se toxicity in …

This work aimed to evaluate Roundup® effects on biochemical biomarkers of the neotropical
fish Prochilodus lineatus. Fish were acutely exposed (6, 24 and 96h) to 10mgL− 1 of …

Antioxidant systems are known to be sensitive to metal exposures and are suggested to use
in predicting sublethal metal toxicity. In this study, several antioxidant enzymes, such as …

Heavy metals are frequently encountered as mixtures of essential and non-essential
elements. Therefore, evaluation of their toxic effects individually does not offer a realistic …

Silver nanoparticles (AgNPs) in the aquatic environment affect ecological repercussions and
have fatal impacts on aquatic animals. The current study examined and correlated the …

Juveniles of the freshwater fish Prochilodus lineatus were exposed to three concentrations
of nickel (Ni): 25, 250 and 2500 µg L-1 or water only for periods of 24 and 96 h to test for Ni …

The aim of this study was to distinguish the impacts of two different anthropogenic conditions
using the honeybee Apis mellifera as a bioindicator associated with a battery of biomarkers …

Living systems encounter a variety of stresses during their continuous interaction with
environment. Environmentally-induced stresses frequently activate the endogenous …
