“…Moreover, for almost four biomarkers used in three tissues (12 biomarkers responses) significant difference between sites and seasons were observed. Similar results were highlighted in many studies from around the world (Ozmen et al, 2008;Cazenave et al, 2009;Güngördü & Ozmen, 2011;Carvalho et al, 2012;Güngördü et al, 2012;Kantati et al, 2013;Silva et al, 2014), showing the importance of spatiotemporal analyses for assessing different effects of pollutants in the environment.…”

Due to intense agricultural activity in the rio Uruguai (South Brazil), there is the potential for aquatic contamination by agrochemicals. In this region, there are many reservoirs to meet the water demand for rice fields, forming lentic environments. In line with this information, the aim of this study was to show a comparative analysis of some biomarkers, such as lipid peroxidation (TBARS), gluthatione S-transferase (GST), non-protein thiols (NPSH), amino acids (AA) and piscine micronucleus tests (MNE) in Astyanax jacuhiensis from lentic and lotic environments in the middle rio Uruguai region, comparing warm and cold seasons. Eight pesticides were found in water samples, with propoxur having the highest concentration found in both environments and seasons. Fish from the warm season showed higher levels of biochemical biomarkers, and fish from the cold season showed higher levels of MNE and AA. TBARS and AA presented higher levels in fish from the river, while GST, NPSH, MNE and AA presented higher levels in fish from dams. These environments have different characteristics in terms of redox potential, aeration, sedimentation, trophic structure, agrochemicals input and others, which may affect the physiological and biochemical responses of fish in against adverse situations.Devido à intensa atividade agrícola no rio Uruguai (Sul do Brasil), há potencial para contaminação aquática por agrotóxicos. Há muitos reservatórios para atender a demanda de água de campos de arroz, formando ambientes lênticos. De acordo com estas informações, o objetivo do presente estudo foi mostrar uma análise comparativa de alguns biomarcadores como a peroxidação lipídica (TBARS), glutationa S-transferase (GST), tióis não-protéicos (NPSH), aminoácidos (AA) e teste písceo de micronúcleos (MNE) em Astyanax jacuhiensis amostrados em ambientes lóticos e lênticos da região do médio rio Uruguai, comparando estações quentes e frias. Oito pesticidas foram encontrados em amostras de água, sendo propoxur a maior concentração encontrada em ambos os ambientes e estações. Peixes da estação quente apresentaram maiores níveis de biomarcadores bioquímicos e peixes da estação fria apresentaram maiores níveis de MNE e AA. TBARS e AA apresentaram maiores níveis nos peixes de rio, enquanto GST, NPSH, MNE e AA apresentaram níveis mais elevados em peixes da represa. Estes ambientes têm características diferentes, com potencial redox, aeração, sedimentação, estrutura trófica, a entrada de agroquímicos e outros que podem afetar as respostas fisiológicas e bioquímicas de peixe contra situação adversa.

“…The accumulation process involves the biological sequestering of metals that enter the organism through respiration and epidermal. It has been indicated that BAFs from environment to fish tissue changes according to the species of the chemical, the metabolite properties of the tissues and the pollution degree of the environment [51]- [53].…”

“…The highest GR activ ity was found in Akyazı (19.32±1.76) but the differences between Akyazı, Sitilce and Bozova were not statistically different (p p≤0.05). Ozmen et al (2008) found enhanced GST activity in liver of carp caughed fro m an area where OCP contamination was highest. GST activity increased when Xenopus laevis tadpoles exposed to six types of OP (C2, C3, C4, C5, C7, and C8) (Gungordu et al, 2013).…”

Residues of organochlorine pesticides (OCPs) were detected in water, sediment and liver tissue samples of the common carp (Cyprinus carpio Linnaeus, 1758) collected from the Ataturk Dam Lake. Ethoxyresorufin O-deethylase, glutathion Stransferase, glutathion reductase, superoxide dismutase, catalase and carboxylesterase activities have been evaluated in liver of Cyprinus carpio. The level of OCPs were determined by Gas Chromatography-M ass Spectrometry. No pesticide residue was determined in the water samples and residues in the sediments were higher than in the fish. In the wet season, the level of pesticides were higher than in the dry season. The concentrations of OCPs were highest in the Akyazı and Bozova areas. Enzyme analysis results showed that the activities were different from region to region and generally higher in Akyazı and Bozova than the other areas. This study is the first study that determines the levels of OCPs of sediment, water and fish in Ataturk Dam Lake and presents pesticide residue levels in the fish samples were above the maximum residue limits so could be a threat to the human health. The presence of OCPs indicates the need for continuous monitoring of the Lake fish population to safeguard the health of the consumers.
