“…Due to direct contact of fish gills with the pollutants and also extensive epithelial surface, structural and physiological changes in this tissue can be used as indicators of environmental pollution and also as a tool for investigating the relationship between exposure to pollutants and biological responses (Oliveira Ribeiro et al, 2006). Hans et al (2006) reported that accumulation of cadmium in some organs of common carp was dependent on time of exposure and doses of cadmium.…”

, 2017. Haematological, blood biochemical and histopathological effects of sublethal cadmium and lead concentrations in common carp. Bulg. J. Vet. Med., 20, No 2,[141][142][143][144][145][146][147][148][149][150] The present research aimed at examining the effects of common carp (Cyprinus carpio) exposure to sublethal concentrations of two non-essential heavy metals: cadmium (Cd: 8.4 mg/L) and lead (Pb: 6.2 mg/L) for 15 days to evaluate occurring biochemical and haematological effects. The examined parameters included haematocrit (Hct), haemoglobin (Hb), lymphocytes (Lym), neutrophils (Neu), total protein (TP), albumin (Alb), immunoglobulin M (IgM), glucose, red and white blood cells counts (RBC & WBC), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), and mean corpuscular haemoglobin concentration (MCHC). Exposure to both metals significantly (P<0.05) reduced the amounts of WBC and MCHC. MCV values decreased (P<0.05) after the Pb treatment but MCV estimates with Cd exposure showed no differences. MCH levels increased in both treatments (P<0.05) whereas Hct, Hb, RBC, Lym, and Neu following both metal exposures were almost similar to those in the control. IgM values were elevated in fish contaminated with both Pb and Cd (P<0.05). The exposed fish showed fusion of gill lamellae, vessel dilatation, hyperaemia, and hyperplasia of gill epithelial cells whereas muscle histology remained unchanged. The observed responses can be secondary to low heavy metals concentrations reflecting the trigger of stress reactions in affected fish.

“…Os peixes são usados na alimentação humana e, devido ao seu potencial de acumular poluentes presentes na coluna d'água, bem como através da biomagnificação pela cadeia trófica, representam uma importante via de contaminação para populações humanas (Oliveira et al, 2006). Nesse sentido, esses animais caracterizam-se pela grande sensibilidade aos poluentes de origem antrópica (Oliveira e Bennemann, 2005).…”

RESUMONeste estudo objetivou-se validar dois órgãos (brânquia e fígado) de Hoplias malabaricus para análise de biomarcadores de contaminação aquática na Área de Proteção Ambiental (APA) do Maracanã em São Luís-MA. Exemplares de traíra foram capturados em uma lagoa de policultivo e no Rio Ambude, localizados na APA do Maracanã. A biometria foi realizada em laboratório. Brânquias e o fígado de cada espécime foram fixados em formol a 10% e mantidos em álcool a 70% até a execução da técnica histológica usual. Cortes de aproximadamente 5µm de espessura foram corados em hematoxilina e eosina (HE). Os resultados referentes à biometria dos peixes capturados durante o período de estiagem indicaram que o comprimento total e padrão dos exemplares foram maiores quando comparados com os indivíduos do período chuvoso. As alterações hepáticas identificadas foram: lipidose, necrose, infiltração leucocitária, vacuolização do citoplasma, hemossiderina e centro de melanomacrófagos. Constataram-se as seguintes lesões branquiais: fusão lamelar, aneurisma lamelar, deslocamento e necrose do epitélio, proliferações de células do muco e dilatação capilar. As respostas biológicas de H. malabaricus, registradas em nível branquial e hepático, podem ser caracterizadas como biomarcadores de contaminação aquática. As brânquias mostraram-se como os melhores órgãos para esse tipo de análise na espécie. Esses resultados indicam que os peixes da região apresentam a saúde comprometida por poluentes presentes nos ambientes analisados.
