“…Other studies have revealed considerable port contamination close to what were identified herein to be important areas for teleost reproduction (Santos et al 2009;Liebezeit et al 2011;Martins et al 2011Martins et al , 2015de Abreu-Mota et al 2014). Obviously, such effects would be best mitigated through far more stringent government control over domestic and industrial effluents.…”

Benthic trawl surveys were performed to quantify the spatiotemporal distributions of teleosts and key abiotic associations throughout an ecologically important estuary within Brazil's Atlantic Forest biosphere. Approximately 52 000 fish (51% juveniles) representing 75 species were sampled, with residents accounting for 36 and 61% of total species and individuals respectively. Five artisanally important species comprised 77 and 81% of individuals and biomass respectively. Cathorops spixii was most abundant (.40% of total), whereas Stellifer rastrifer, Aspistor luniscutis, Sphoeroides greeleyi and S. testudineus collectively contributed towards 37 and 34% of individuals and biomass respectively. The abundance of A. luniscutis, C. spixii and S. rastrifer was negatively associated with salinity, whereas the presence of the latter two species was also positively associated with temperature, and S. greeleyi and S. testudineus (mostly adults) were more abundant in deeper areas. These relationships seemed to be affected by species-specific reproductive (S. rastrifer, C. spixii and A. luniscutis), habitat (S. greeleyi and S. testudineus) and prey preferences (juvenile C. spixii and A. luniscutis). Protection for these various species may be achieved via immediate fishing effort regulations, but more research is required to manage other anthropogenic effects. Such work should be a priority to ultimately preserve what is one of the most important South American biodiversity areas.

“…A large partmajor portion of the fluxes of the natural and anthropogenic materials introduced into coastal systems tend to accumulate in sediments, producing unequivocal geochemical signatures within sedimentary bodies, thus registering changes in time (Bruland et al, 1974). These anthropogenic geochemical signatures include elevated levels of contaminants such as metals (Bai et al, 2016;Begy et al, 2016;Garcia-Orellana et al, 2011), polycyclic aromatic hydrocarbons (PAHs) (Martins et al, 2015;Peng et al, 2008), pesticides (Alonso-Hernández et al, 2015;Kaiser et al, 2016), polychlorinated biphenyls (PCBs) (Combi et al, 2016;Ruiz-Fernández et al, 2012), in addition to changes in Pb isotopic composition (Nriagu and Pacyna, 1988;Waters et al, 2016;Yu et al, 2016;Zhang et al, 2016).…”

The evolution of the impacts of anthropogenic activities in Todos os Santos Bay was evaluated by profiles of trace metals and Pb isotopes determined in sediment cores. Fluxes of metals increased up to 12, 4 and 2 times for Cu, Pb, and Zn, respectively, compared to those recorded in the beginning of the 20 century. Stable Pb isotopes identified a decommissioned lead smelter and burning of fossil fuels as the main sources of Pb. Most metals showed minor to moderate enrichment factors (EF<4), but Cu and Pb were highly enriched (EF=28 and 6, respectively) at the Aratu harbor. Temporal changes in sediments were associated to different activities, namely Pb smelting, burning of fossil fuels, maritime traffic, petroleum related activities, inputs of domestic effluents, and changes in land uses. The effects of the implementation of environmental policies to improve the waters of the bay could not be identified in the evaluated cores.
