“…The study by Ç avas (2011) demonstrated the genotoxic potential of triazine on fishes, showing significant increases in the frequencies of MN and DNA strand breaks in erythrocytes of Carassius auratus following exposure. This pesticide also causes histopathological damage (Mela et al 2013). The organophosphorous insecticides are known to cause histopathological damage in the liver and gills (Fanta et al 2003) and to inhibit acetylcholinesterase activity (Silva et al 1993;Bálint et al 1995).…”

We aimed to assess the quality of a midsize river that receives agricultural and urban wastewater. Nuclear abnormalities (NA), comet assays of blood and gills, and gill histopathology were evaluated in fish Astyanax aff. paranae during the summer and winter 2011 at three sites in Paraná State, Brazil: (1) a biological reserve (Rebio-reference area); (2) an agricultural site; (3) a downstream site that accumulates agricultural and urban effluents. We found the highest effects of pollutants in fish at the downstream site during the summer. The agricultural site showed an intermediate damage rate, and fish at Rebio generally had the least damage, with the exception of NA. Despite conflicting results from the biomarkers used, we observed an increase in damage associated with the accumulation of pollutants. Pesticides are probable xenobiotics in the agricultural area. Additionally, metals and substances such as pharmaceuticals and ammonia may be present at the downstream site.

“…The SOD increase observed in carp may be justified by the process of adaptation in an attempt to detoxify the organism from oxygen free radicals and to prevent damage to macromolecules such as lipids. CAT activity is responsible for the detoxification of H 2 O 2 into water as a way of cellular defense against oxidative stress (van der Oost et al 2003;Mela et al 2013). The observed absence of response for CAT activity and the SOD inhibition in liver of silver catfish could be explained by the increase in free radical formation due to clomazone exposure.…”

Clomazone is considered a potential contaminant of groundwater and is persistent in the environment. To verify the effects of clomazone in Cyprinus carpio and Rhamdia quelen, a method that combines biomarker responses into an index of "integrated biomarker response" (IBR) was used for observed biological alterations in these species. Thiobarbituric acid-reactive substances in liver of carp and silver catfish decreased at both concentrations tested. However, in muscle it increased in carp at 3 mg/L and silver catfish at 6 mg/L. Protein carbonyl increased in liver (3 and 6 mg/L) and muscle (6 mg/L) of carp. In carp, superoxide dismutase (SOD) increased at 3 mg/L and catalase at 6 mg/L. In silver catfish, SOD in liver decreased at 3 mg/L. Glutathione-S-transferase increased at 3 mg/L in muscle of carp. Nonprotein thiol levels decreased at both concentrations in liver of silver catfish and muscle of carp. In silver catfish, acetylcholinesterase (AChE) decreased in brain at 6 mg/L. Nevertheless, AChE in muscle of both species increased at 3 and 6 mg/L. IBR was standardized scores of biomarker responses and was visualized using star plots. The IBR values shown that in carp there was predominantly an induction of parameters, whereas in silver catfish there was inhibition of these responses. In this way, IBR may be a practical tool for the identification of biological alterations in fish exposed to pesticides. In the present study, IBR was efficient for comparisons of fish species using clomazone. This study may serve as a base for evaluation of other pesticides in the rice field, environment, or laboratory experiment.

“…GSH has several important functions, for example in scavenging ROS and electrophiles, maintaining thiol-disulfide redox equilibrium, and in signal transduction (Valko et al, 2006;Backos et al, 2012). Toxicant exposure was previously reported to reduce hepatic GSH content in silver carp, common carp, and zebrafish (Atencio et al, 2008;Jin et al, 2010), and similar declines in GSH levels in fish liver were reported to be induced by chlorophenol, atrazine, and other chemicals (Sun et al, 2008;Mela et al, 2013). In the context of the present work on cyanobacterial neurotoxins, decreased GSH content was recently detected in the liver of freshwater fish Hoplias malabaricus exposed to saxitoxins (cyanobacterial neurotoxins) (Silva de , and similar decreases in GSH levels were recorded in the liver of Perca fluviatilis exposed to an A. flos-aquae bloom (Perendija et al, 2011).…”

“…In fish liver, agents reported to induce lipid peroxidation include cyanobacterial hepatotoxins, herbicides, and heavy metals (Almeida et al, 2009;Mela et al, 2013). However, data are limited concerning lipid peroxidation in fish liver following exposure to cyanobacterial neurotoxins or PSPs.…”
