Effects of four rice herbicides on some metabolic and toxicology parameters of teleost fish (Leporinus obtusidens)

Atrazine-Mediated Oxidative Stress Responses and Lipid Peroxidation in the Tissues of Clarias gariepinus

“…The decrease in AChE activity is suggestive of atrazine toxicity which might have caused accumulation of acethylthiocholine at neuromuscular junction and disruption of synaptic transmission in the cholinergic system of the fish. Induction or inhibition of AChE in fish tissues can influence cholinergic transmission process, thus eliciting undesirable effects [32]. Inhibition of AChE has been reported in fishes exposed to different pesticides [33].…”

Environmental Pollution and Oxidative Stress in Fish

“…The increase in catalase activity is often observed in the model experiments and also can occurre without relation to SOD responses and due to high pollutant impact (Üner et al, 2005;Moraes et al, 2007;. The higher catalase activity was reported for the liver subcellular fractions of red mullet Mullus barbatus collected along the Western Mediterranean coast (the Northern Iberian Shelf).…”

Assessment of water pollution in the Brazilian Pampa biome by means of stress biomarkers in tadpoles of the leaf frog Phyllomedusa iheringii (Anura: Hylidae)

“…Several studies using fish species have shown inhibition of cholinesterase activity in the presence of organophosphate compounds in water (Sancho et al, 1997;Dutta and Arends, 2003). In addition to organophosphate and carbamates, other agricultural compounds such as glyphosate are shown to inhibit AchE in fish (Moraes et al, 2007). Regarding organophosphate compounds in frogs, recent studies have shown the accumulation of such compounds in amphibians (Kittusamy et al, 2014).…”
