“…Similar to our study, high levels of CYP1A were also registered in the livers of caged mummichogs, Fundulus heteroclitus, exposed to contaminated sites in the vicinity of an oil refinery (Loughery et al, 2014). In sites located in the vicinity of S6, previous analysis of greases and oils suggests that the water contamination comes from domestic sources and from a local petroleum refinery (Niencheski and Baumgarten, 2010). Our sediment analysis shows a high total concentration of 16 PAHs (4414.0 ng g À1 ), a value close to that previously found by Medeiros et al (2005) in the same area (4430 ng g À1 ) (Medeiros et al, 2005).…”

“…S3 is located in the residential area of the beach, which receives domestic sewage discharges. S4 is an artificial channel that runs through the city and is contaminated by domestic sewage and urban runoff (Niencheski and Baumgarten, 2010). P. caudimaculatus was collected at sites S5, S6 and S7 (Fig.…”

“…Nas regiões com circulação mais restrita, como a Ilha dos Marinheiros e o Saco da Mangueira, os processos de troca de água foram menos intensos, propiciando um maior tempo de residência das águas salobras. No entanto, mesmo com os ventos de SO induzindo a entrada da cunha salina, em geral o Saco da Mangueira apresentou aguas doces à salobras, assim como já observado por Niencheski & Baumgarten (2007).…”

“…A entrada de aguas costeiras no estuário favorece a sua oxigenação e a diluição da matéria orgânica originada das atividades antrópicas, reduzindo assim, o consumo de oxigênio para decomposição desta matéria; auxiliando na melhoria da qualidade da água da região (Niencheski & Baumgarten, 2007), isto pode ser a causa de não ocorrerem situações anóxicas no Saco da Mangueira, mesmo com a elevada concentração de nutrientes.…”

This work assesses the influence of Patos Lagoon-RS hydrodynamics in the behavior of water quality indicator variables as like suspended material, dissolved oxygen, dissolved inorganic nutrients and chlorophyll-a. Also gives an assessment of the effect of effluent discharge in the magnitude of the concentrations of these variables and in their interrelationships. To develop this study we applied the numerical model MOHID 2D, successfully applied in environmental management of coastal areas. The results indicate that Patos Lagoon is a heterogeneous system in which its hydrodynamic is governed mainly by the action of wind and river flow, which directly influence the behavior of water quality variables. Furthermore, the presence of effluent significantly changes the magnitude of the nutrients and chlorophyll-a concentration, particularly in areas close to the sewage launch sites. We concluded that the numerical modeling is an important tool for the dynamics systems management and that ecological variables are not only conditioned by their interrelations, but also by system circulation.

Patos Lagoon is the largest choked coastal lagoon in the world (250 km long, 40 km wide and mean depth of 5 m), with banks formed by sand and predominantly muddy bottom. The circulation is mainly driven by wind and river flow, with a minor contribution of the local microtidal regime. This lagoon is one of the most studied coastal water bodies in Brazil. The Patos Lagoon suspended particulate matter (SPM) data compendium consists of over four decades of SPM data gathered from multiple research and monitoring projects. Data consist of SPM in situ samplings, remote sensing derived SPM estimates, rating curve approach for SPM estimates and SPM derived from turbidity measurements. Only measurements with a detailed description of the sampling and analysis protocols were used. The present data set offers valuable contributions as it allows the assessment of trends on the data and the short-and long-term spatial and temporal variability of SPM concentrations in an area where permanent monitoring stations are not available. From these records, the SPM concentrations ranged from 0.4 g/m 3 up to 1,000 g/m 3 . The Patos Lagoon SPM Compendium has been made publicly available at Tavora, Fernandes and Möller (2020).
