“…These two sites (HB and CO) of Paranaguá bay are known to be impacted by harbor activities and human occupation (Sá et al, 2006;Choueri et al, 2009;Santos et al, 2009;Martins et al, 2010;Santos et al, 2014). The reference site (RF) is on the Guaratuba bay, a remarkably non-impacted bay, as described by several recent studies (Combi et al, 2013, Rodrigues et al, 2013, Madi et al, 2015, Prodócimo et al, 2015. We transported the fish to a research station right after the sampling, and obtained the total weight (TW) and length (TL).…”

“…Guaratuba bay, used in this study as reference site, is a touristic area and commonly known for low-scale fishing, angling, banana and citrus cultivation, and mariculture (Mizerkowski et al, 2012). Even so, the levels of contamination found are acceptable for the activities aforementioned (Combi et al, 2013;Rodrigues et al, 2013;Madi et al, 2015;Prodócimo et al, 2015).…”

A multi-biomarker approach was used to evaluate the liver health of two Neotropical fish species (Cathorops spixii and Atherinella brasiliensis) that inhabit two different sites of the Paranaguá bay (Paraná-Brazil) and a reference site in the Garatuba bay. Fish were sampled during summer and winter, so the variation of the responses can reflect the actual conditions of sampling sites. Data showed that fish from both sites of the Paranaguá bay are affected by the presence of pollutants from different sources. Both fish species presented adverse biomarker responses mainly in the summer, probably due to the increased human population during the period. Chronic effects in the liver related with the contamination. Thus, the results demonstrated that pollution in Paranaguá bay induce liver damage in fish that inhabit this area.

Depuration time and sublethal effects of microcystins in a freshwater fish from water supply reservoir

Microcystins (MCs) are hepatotoxins that have been considered to be a worldwide problem due the effects that they can cause to environmental and human health systems. The Iraí Reservoir, located in the South of Brazil, is used as a water supply and MCs concentrations have been reported in this ecosystem. This study aimed to determine the MCs concentrations in the Iraí Reservoir and to evaluate the MCs depuration time and the health of Geophagus brasiliensis using biomarkers. Water and fish samples were collected in the Iraí Reservoir from August 2015 to May 2016. Phytoplankton and chemical analyses were conducted using water samples and the fish were divided into two groups; the Immediate Group (IMM) and the Depuration Group (DEP). In the IMM group, the blood, liver, muscle, brain and gills were collected, in order to evaluate the genotoxic, biochemical and chemical biomarkers. The DEP group was used in the depuration experiment for 90 days, and after this period the fish were submitted to the same procedure as the IMM group. Our results suggested that fish accumulated MCs and it may have caused oxidative stress, neurotoxicity and molecular damage. Furthermore, MCs concentrations increased during the depuration time and it resulted in molecular damage over the first 30 days. After 90 days, the recovery of the antioxidant system occurred. The depuration started on the 15th day, however, the toxins were still present in the samples. Therefore, the effects and the persistence of MCs are a risk to environmental systems and human health.
