Biomarkers responses in fish (Atherinella brasiliensis) of paranaguá bay, southern Brazil, for assessment of pollutant effects
Paranaguá bay is a complex estuary located in southern Brazil containing three protected areas listed by UNESCO. Historically, the estuary has been affected by urban, industrial, agricultural and harbor activities, and occasional accidents. Specifically, the explosion of the Chilean ship Vicuña in D...

| description | Paranaguá bay is a complex estuary located in southern Brazil containing three protected areas listed by UNESCO. Historically, the estuary has been affected by urban, industrial, agricultural and harbor activities, and occasional accidents. Specifically, the explosion of the Chilean ship Vicuña in December 2004 spilled methanol and crude and fuel oils which affected both protected and non-protected areas. The present study sought to investigate the pollution threat to aquatic organisms in order to evaluate the potential effects of pollutants. One hundred and twenty adult fish Atherinella brasiliensis were collected from different sites within Paranaguá estuary, including the harbor and open ocean, during summer, autumn and winter of 2005. Among the biomarkers, the somatic index, chemical analysis of bile, biochemical, genetic and morphological parameters were considered. Chemical analysis of bile showed a continuous bioavailability of polycyclic aromatic hydrocarbons (PAHs) according to proximity to the harbor site. The histopathological findings have demonstrated aconsiderable incidence of severe pathologies in the liver and gills, corroborated by biochemical disturbances and genetic damage. These findings indicate that more studies are necessary to evaluate both water quality and fish health so as to permit a better analysis of the impact of pollution in Paranaguá estuary.<br>A Baia de Paranaguá é um complexo estuarino localizado no sul do Brasil constituído de três áreas de proteção ambiental listadas pela UNESCO. Historicamente, o estuário tem sido afetado por atividade urbana, industrial, agricultura e portuária, e eventualmente por acidentes. Particularmente a explosão do navio Chileno Vicuña em dezembro de 2004 derramou metanol, óleo cru e combustível atingindo áreas protegidas e não protegidas. O presente estudo tem por objetivo investigar a poluição em organismos aquáticos. Cento e vinte indivíduos adultos do peixe Atherinella brasiliensis foram coletados em quatro diferentes pontos de coleta no estuário de Paranaguá, partindo do porto até o oceano aberto nos períodos de verão, inverno e primavera de 2005. Os índices somáticos, parâmetros químicos, enzimáticos, genéticos e morfológicos foram considerados. As análises histopatológicas demonstraram expressiva incidência de patologia no fígado e nas brânquias algumas vezes corroboradas pelas alterações bioquímicas. Danos genéticos e anormalidades genéticas também foram observados. As análises químicas na bile mostraram uma contínua biodisponibilidade de hidrocarbonetos policíclicos aromáticos para os organismos aquáticos. Os dados obtidos indicam que a qualidade da água e a saúde dos peixes encontram-se bastante comprometidos no estuário de Paranaguá. |
