“…Their methods have been applied with more importance to estimate the quality of water, sediments, soils, and the atmosphere (Reis et al, 2013;Jiang et al, 2014;Camargo et al, 2015). Camargo et al (2015) asserts that sediments are an important indicator of the health of aquatic ecosystems because they naturally work as a metal reservoir, due to the capacity of holding more than 90% of metals in the aquatic environment (Zahra et al, 2014). Thus, sediments are a potential secondary source of metals which might be released back into water columns along with changed environmental conditions .…”

Surface sediments collected in the intertidal zone of Paraguaçu estuary in July, 2013, were analyzed for organic matter, nitrogen, phosphorus, grain size fractions and partial concentrations of 16 metals. The USEPA 3051A method and ICP-OES and CV-AAS techniques were chosen to metal analysis. Pollution indices (EF, Igeo and PIN) and a comparison with sediment quality guidelines (UET, ERL, ERM, TEL and PEL of NOAA) were conducted in order to evaluate the potential metal impacts over the area. Principal Component Analysis (PCA) and Pearson correlation results showed the importance of organic matter content and the fine-grained fraction of sediments on the control of the bioavailable metals distribution. The Paraguaçu estuary already has anthropogenic enrichment relative to the background level, especially for Mn, whose values exceeded almost 30 times the background at one site (Mn: 1197.30 mg kg(-1)). However, metal levels are still below the reference values with the exception of Hg at one site (Hg: 0.25 mg kg(-1), exceeded TEL and ERL).

“…Em contraste, a presença de estrógenos em sedimentos ou solo apresenta-se em menor número de referências, que são ainda menores do que os relatados em águas. Somente poucos trabalhos têm relatado métodos analíticos para a determinação de compostos orgânicos para essas matrizes sólidas (GABET et al, 2007 CAMARGO et al, 2015). Diante disso, identificar fontes potenciais de metais nos sedimentos e repartir suas contribuições é de importância fundamental para propor estratégias de prevenção e controle da poluição do rio .…”

“…Although the latter has been considered a confounding factor in ecotoxicological studies (Ankley et al, 1992;Ward et al, 2011), since it can occur naturally, ammonia can also interact with other contaminants and have additive or synergistic effects that considerably increase toxicity (Ankley et al, 1990). It was shown that in the presence of ammonia, sediments presenting moderate levels of contamination become toxic (Araújo et al, 2013;Camargo et al, 2015). Therefore, even when contamination levels are low to moderate, due to the presence of ammonia and detergents, they are still harmful to biota in many instances (Phillips et al, 1997;Abessa et al, 2014a).…”

The Santos-São Vicente Estuarine System has a long history of environmental impacts, and several studies have been performed in this region. However, the quality of its tributaries was not previously studied. This study aimed to investigate the quality of sediments from five rivers (Santana, Mariana, Piaçabuçu, Quilombo, and Diana Rivers) and three sampling sites at Piaçaguera Canal (riverbed, right and left banks), by using an integrated approach involving chemical analyses and whole sediment toxicity tests. Chronic and acute toxicity tests were performed using, respectively, copepods Nitocra sp. and amphipods Tiburonella viscana. The studied sediments presented moderate to high levels of PAHs, PCBs, metals (Cu, Hg, Ni, Pb, Zn), and As. The majority of sediments produced chronic toxic effects, and samples from Piaçaguera Canal were consistently toxic in all acute and chronic tests. The integration of data through multivariate analyses indicated that the toxicity was closely related to the sediments contamination. Chemical data were compared with sediment quality guidelines, which evidenced that the sitespecific values are adequate to predict impacts. The levels of organic chemicals and metals suggest constant inputs from diffuse and point sources, demanding actions to ensure effective control and management of the contamination sources to the estuary.
