“…Regarding rice pest management, the surveyed farmers used several recommendable strategies such as the combination of hoe weeding and selective herbicides for weed control, 53,54 the used of human bird scares and scarecrows for bird control, 39 and traps for rodent control 55 . However, some surveyed farmers used glyphosate as herbicide even though it is known that glyphosate is harmful to the environment and human health, and poses health risks to fish populations inhabiting rice fields 56 . It is therefore important to develop alternative weed control such as the use of rice varieties with high weed‐suppressive potential 57 .…”

“…As for the HSI, it was observed in G. stomatus the lowest K value among the analyzed species. The K is often associated to water quality and food availability, hence indicator of the sh health (Van der Oost et al 2003;Rossi et al 2020). This index may be reduced by the presence of pollutants given the increased metabolic activity and demand of energy for detoxi cation process, altering the sh feeding rate (Heath 1995).…”

The present study aimed at evaluating the environment quality of the Santa Cruz Channel estuary (area 1) and Sirinhaém river estuary (area 2), Northeastern Brazil, using histopathological biomarkers of liver and gills of fish species with different trophic levels as indicators. It was collected liver and gills from five species: Bairdiella ronchus (n=24) and Gobionellus stomatus (n=34) in the area 1; Caranx latus (n=35), Centropomus undecimalis (n=24) and Centropomus parallelus (n=29) from area 2. The liver showed several damages, such as, hepatic steatosis, necrosis, vacuolar degeneration, and infiltration. Centropomus undecimalis had the highest Histopathological Index of Liver (HIL). Gills exhibited moderate to severe alterations for all species, such as the lifting of epithelial cells, lamellar aneurysm, and rupture of the lamellar epithelium. Centropomus undecimalis in area 2 and G. stomatus in area 1 had the higher number of alterations in their organs. Both areas have been historically affected by mercury (Hg) pollution in área 1 and by the sugarcane industry in area 2 and the species used as biomarkers has been proven to be severely damaged in both estuaries. Species chosen in this study were considered good bioindicators of pollution and the combination of biomarkers methodologies in two organs, pioneering in the Northeastern of Brazil, was efficient in diagnosing the health status of the area using fish as bioindicator.

“…W mózgu ryb pod wpływem działania chlorpyrifosu -pestycydu fosforoorganicznego -zaobserwowano zmniejszenie aktywności enzymu acetylocholinoesterazy odpowiedzialnego za rozkład neuroprzekaźnika -acetylocholiny na cholinę i resztę kwasu octowego. Przyczynić się to może do zaburzenia kaskady reakcji na poziomie ośrodkowych i obwodowych układów neurohormonalnych, co może spowodować nieprawidłowe zachowania behawioralne (35). Rybie zarodki, które były narażone na ekspozycję pestycydów, później osiągały dojrzałość płciową, a także wykazywały zaburzenia w działaniu szlaków sygnałowych związanych z reprodukcją (27).…”

The comet assay method is a research technique for detecting damage to cellular DNA due to active physical or chemical agents. The comet assay is based on electrophoretic migration of genetic material contained in the cell’s nucleus. This research method is commonly used in many different fields, such as toxicology, environmental protection, and pharmacology. In recent years, the comet assay has attracted considerable attention from scientists studying the effects of harmful substances on the genetic material in the cell’s nucleus. The presence of pesticides in the environment is a threat to animals, because of the negative effects of pesticides on cells and their genetic material. Therefore, the aim of this paper, based on the available literature, was to describe the use of the comet assay in assessing the genotoxicity of pesticides to cells of aquatic organisms, as well as to describe the methodology and potential complications of this procedure.
