Multiple lines of evidence of sediment quality in an urban Marine Protected Area (Xixová-Japuí State Park, SP, Brazil)

Natural factors and chemical contamination control the structure of macrobenthic communities in the Santos Estuarine System (SP, Brazil)

“…Despite the influence of contaminants released by port and industrial activities, recent studies also showed that the vicinities of the SSOS present contamination by contaminants of emerging concern (CECs), such as phenols, hormones, fecal sterols, pharmaceutical and personal care products, drugs of abuse, and others (Santos et al 2018, Pereira et al 2016. Our results are in agreement with previous studies carried out in the SES , 2005, and after our sampling campaing, other studies corroborated our findings (Sousa et al 2007, Cesar et al 2006, Rachid, 2002, Prósperi et al 1998, Araújo et al 2013, Buruaem et al 2013, Moreira et al 2019.…”

“…Such pattern had been described previously by Tommasi (1979), but the specific composition of assemblages differed from those observed in the present study. A further study conducted by Moreira et al (2019) confirmed the trends ob- served at the west of Santos Bay, with dominance of polychaetes (Cirratulidae and Capitellidae) and presence of sensitive organisms such as amphipods. The pattern exhibited by Shannon diversity (H') was similar to species richness and values were low compared to a previously investigation (Tommasi, 1979), which can be attributed to differences in sampling strategy.…”

“…In this investigation, the toxicity occurred even when the NH 3 levels were low, suggesting that other contaminants were probably responsible for the toxicity. Some recent publications reported that ammonia is an important contaminant to the SES and is capable of interacting with other substances, increasing the toxic effects to benthic organisms (Araújo et al 2013, Camargo et al 2015, Moreira et al 2019. A qualitative interpretation of the ammonia influence on the porewater toxicity is presented on the Supplementary Material (Table S7).…”

Economic evaluation of the impacts of water quality on fishery production in the Estuary Complex of Santos, São Vicente and Bertioga cities, in southeastern coast of Brazil

“…This assertion is not only based on data observed in research, but also on information generated by several authors and papers carried out in the study region, which also considered surface water and sediment. (BRAGA et al, 2000;MOREIRA et al, 2018;PERINA et al, 2018;DUARTE et al, 2019;GONÇALVES et al, 2020).…”

“…In the Estuarine Complex of Santos, São Vicente, and Bertioga Cities, located along the Brazilian southeastern coast, the industrialization process and development became a source of income, generating migration cycles and potential risks of pollution, considering that the industrial activities of this region were responsible for releasing several potentially toxic substances in the aquatic environment (CETESB, 2016). In addition, the disordered land use and its effects, in terms of sedimentation of the bodies of water, increase in the sedimentation rate and flood, coupled with water pollution due to domestic effluent releases, reflect the currently high eutrophic character of the region, showing no improvement over time (BRAGA et al, 2000;CETESB, 2016;MOREIRA et al, 2018;PERINA et al, 2018;GONÇALVES et al, 2020).…”
