“…In this study, nuclear abnormalities frequencies found in control animals and in animals exposed to both Al concentrations were considered low. However, our results are in accordance with several other authors, which also report a higher frequency of abnormalities in ish peripheral erythrocytes, in comparison with the micronuclei frequencies (FERRARO et al, 2004;CAVALCANTE et al, 2008;OLIVEIRA-MARTINS;GRISOLIA, 2009;MURANLI;GÜNER, 2011). Therefore, the concomitant analysis of nuclear abnormalities could represent an alternative to overcoming a possible lack of sensitivity related to the general low micronuclei frequency in ish erythrocytes (AYLLON, GARCIA-VAZQUEZ, 2000;GUILHERME et al, 2008;MONTEIRO et al, 2011).…”

http://dx.doi.org/10.5007/2175-7925.2016v29n1p75A contaminação de ecossistemas aquáticos por alumínio (Al) é geralmente ocasionada por várias atividades antropogênicas. Diversas alterações morfológicas, fisiológicas e bioquímicas observadas em organismos aquáticos podem ser atribuídas à exposição ao Al. Neste contexto, o objetivo desse estudo foi investigar os efeitos da exposição aguda de peixes da espécie Astyanax jacuhiensis a diferentes concentrações de Al através da histologia de brânquias e frequência de micronúcleos (MN) e anormalidades nucleares (AN) em eritrócitos. Os animais foram expostos às concentrações subletais de 0.3 mg/L e 30 mg/L de alumínio em pH neutro por 72 h. Um grupo controle foi mantido em água filtrada. As alterações branquiais foram caracterizadas por hiperplasia e hipertrofia de células epiteliais, fusão lamelar, edema, descolamento epitelial, aneurisma e necrose. Um aumento significativo (p<0.05) foi observado na frequência de lamelas alteradas nos grupos expostos às duas concentrações de Al em comparação aos animais controle. No entanto, não foram observadas diferenças significativas nas frequências de MN e AN. Embora não tenham sido encontradas evidências de genotoxicidade, os resultados encontrados na análise morfológica sugerem que o Al foi tóxico para os peixes nas duas concentrações testadas em pH neutro.

“…Different organisms such as culture cells, fish, algae, bacteria, shrimp, higher plant and other microorganisms may be used for this purpose. It is reported that the effluent meets all physicochemical requirements, regarding its toxicity, it may cause considerable negative effects on living organisms 5,[32][33][34] . In this regard, attempt have been carried out to study the toxicity of industrial wastewater after the application of advanced oxidation processes by various researchers [35][36][37][38][39][40] .…”

From last few decades, there is a growing concern of chemical pollution due to their harmful effect on living organisms. The water bodies serve as temporary or final receptors of diverse variety of contaminants, which are consequently contaminating the watersheds and adjoining territories 1,2. The rapid stride in industrialization is a major concern which is jeopardizing the ecological balance 3. Among the damages caused by chemical agents to exposed organisms, genotoxic and mutagenic effects have shown to be worrying, which can lead to several health problems and also affect future generations due to inheritable alterations in genetic material. Genetic toxicology involved in detecting compounds capable of causing genetic damage with the aim of understanding potential biological penalty 4,5. The effluents discharged from industries enter into the water bodies in several different ways, either dumped directly, such as industrial effluents, or from wastewater treatment plants that do not fulfill their obligations. Due to universal solubility nature of water, almost all kinds of substances can be transported and distributed more easily in the water cycle 6,7,8. At present, the safe disposal of industrial wastewater is one of the major ecological challenges. Therefore, environmental degradation has now become a global problem and to main

The sublethal effects of water-soluble fraction of gasoline (WSFG, 1.5 % v/v) were evaluated in the freshwater fish, Astynax altiparanae, after acute exposure (96 h) under a semi-static system. In addition, the recovery process was assessed in the fish following contaminant depuration. Recovery treatments were carried out with gradual depuration (GD), consisting of 7 days in the WSFG, followed by 8 days in clean water; and treatments with total depuration in clean water for 15 (DEP 15) and 30 days (DEP 30). The effects were evaluated through the piscine micronucleus test and by differential counting of organic defense cells. Acute exposure increased the frequency of neutrophils. In the GD treatment, the thrombocyte count and erythrocytic nuclear abnormalities (ENA) increased. In the DEP 15 treatment, there was a reduction of ENA; and following 30 days of depuration (i.e., DEP 30), the number of lymphocytes increased and the thrombocyte count remained high. These results indicate a long-term response to a condition of stress from WSFG.
