“…The easy accessibility of rivers for the disposal of domestic and industrial wastes has made them very susceptible to pollution, especially by anthropogenic activities [5]. Among the most notorious water pollutants are heavy metals, which are a group of contaminants long detected as a threat to aquatic organisms and humans, even at trace concentrations [6,7]. They are known for their toxicity and persistence in the environment [8,9].…”

Abstract:Trace metals contamination of rivers and sediments remains a global threat to biodiversity and humans. This study was carried out to assess the variation pattern in trace metals contamination in Mvudi River water and sediments for the period of January-June 2014. Metal concentrations were analyzed using an inductively-coupled plasma optical emission spectrometer after nitric acid digestion. A compliance study for the water samples was performed using the guidelines of the Department of Water Affairs and Forestry (DWAF) of South Africa and the World Health Organization (WHO). The National Oceanic and Atmospheric Administration (NOAA) sediment quality guidelines for marine and estuarine sediments and the Canadian Council of Ministers of the Environment sediment guidelines (CCME) for freshwater sediments were used to determine the possible toxic effects of the metals on aquatic organisms. pH (7.2-7.7) and conductivity (

“…Esto podría indicar que los genotoxicos que producen más daño en el ADN, también afectan más número de células. Otros estudios demuestran que el efecto que produce alteraciones en el material genético es probablemente causado, además, por la presencia de metales, incluyendo el hierro, manganeso, cobre, zinc y arsénico, debido a su alta actividad mutagénica y genotoxica [30]. Se ha demostrado que los iones metálicos presentes en algunos pesticidas pueden interferir con la reparación del ADN y producir especies reactivas de oxigeno (ROS), que conducen a daño oxidativo [31].…”

El durazno es la segunda especie frutal de mayor importancia después del manzano, en las rosáceas. Los pesticidas son considerados como uno de los principales factores de contaminación del medio ambiente; como es conocido son ampliamente utilizados para mejorar la producción de alimentos en la agricultura y para el control de plagas y vectores de enfermedades; muchos han sido clasificados como cancerígenos, porque inducen daño en el material genético. En este trabajo se determinó la genotoxicidad producida por extractos de durazno (Prunus pérsica (L.)Batsch) cultivados en el municipio de Pamplonita, Norte de Santander. El ensayo cometa fue utilizado para la evaluación de la actividad genotóxica. Para la detección de residuos de pesticidas, se usó cromatografía de gases µECD. Los resultados indican que el extracto de durazno induce lesiones en el ADN de linfocitos humanos, que varían de acuerdo a la dosis del extracto; por cromatografía, se detectaron pesticidas como endosulfan II y el Beta BHC, que pertenecen a la familia de los organoclorados. Dado que el durazno es un producto de exportación y de alto consumo en nuestra región, la ingesta de este podría convertirse en un factor de riesgo para la población

“…There is rich documented literature witnessing research on molecular level of different fish species showing ill effects of pesticides on genes and DNA levels (Stahl, 1991;Helma et al, 1996;Mitchelmore and Chipman, 1998;White et al, 1998a;White et al, 1998b;Hose and Brown, 1998;Hartmann et al, 1999;Gartiser et al, 2001;Vargas et al, 2001;Çavas and Könen, 2007).…”

| Throughout the world pesticides are widely employed in agriculture sector in order to elevate crops' yield with low labour and efforts. Pesticides exposure leads to toxicity in many non-target organisms, fish being one of the most prominent among these. Most of the time acute concentration of these pesticides leads to mortality while sub lethal concentration of these pesticides result in different lethal changes. These changes may be in behaviour of the exposed fish such as change in feeding behaviour, attack or avoiding behaviour and reproductive behaviour, or other types of alterations such as changes in histology (liver, kidneys, gills, muscles, brain, intestine), haematology (RBCs, WBCs or Plasma), anti-oxidant defence system (Glutathione reductase, Peroxidase, Catalase, Superoxide dismutase, Glutathione peroxidase, Glutathione-S-transferase etc.), changes in nutrient profile (Protein, Lipids, Carbohydrates, Moisture content and Ash etc.) and worth of the fish, hormonal or enzymatic alterations, oxygen consumption, and DNA damage or damage at genes level (genotoxicity). Different environmental agencies are working on this aspect and that's why there are a large number of banned chemicals. Still these chemicals are available in markets. Certain newly synthesized pesticides (insecticides or fungicides etc.) and extensive use of these chemicals are always there to maximize the problem for aquatic organisms especially fish. This article focuses on the same aspect of ecotoxicology and reviews some major induced toxicological aspects of pesticides in fish including behavioural changes, histopathological damages, haematological alterations, biochemical changes, fluctuations in acetylcholinesterase activity, vicissitudes in protein contents, induced genotoxicity, alterations in feeding biology, oxygen consumption and oxygen stress all across the world.
