“…Furthermore, due to a Pb-mining activity that lasted from 1945 to 1995 in the upstream area of the Ribeira River, the lagoon system received contaminated sediments, with enrichment factors as high as 20 times the natural regional background (de Mahiques et al, 2012) (figure 6). Nowadays, despite the cessation of the mining activities, the system still receives significant quantities of metalenriched sediment since the mining debris are still deposited in the margin of the river (Tramonte et al, 2015).…”

“…From the original dimensions of 4.4 meters wide per 2 meters the channel presently shows widths of approximately 250 meters per depths of about 7 meters. Nowadays, about 60% of the freshwater and suspended sediments carried by the Ribeira River, the most important coastal river in São Paulo, reach the lagoonal system, with a consequent modification of environmental conditions (Martinez et al, 2013) and intense siltation (De Mahiques et al, 2014), forming several islands at the mouth of the artificial channel (figures 4 and 5).Furthermore, due to a Pb-mining activity that lasted from 1945 to 1995 in the upstream area of the Ribeira River, the lagoon system received contaminated sediments, with enrichment factors as high as 20 times the natural regional background (de Mahiques et al, 2012) (figure 6).

“…Contudo, esse ecossistema vem sendo drasticamente afetado, ao longo de mais de um século, pelo aporte continental exógeno do rio Ribeira de Iguape (RI) após a abertura do canal artificial do Valo Grande (VG; Mahiques et al, 2012). Na presente tese, uma detalhada avaliação do impacto desse aporte na ictiofauna é conduzida, que poderá subsidiar o futuro plano da recuperação ecológica do ECI (DAEE, 2011).…”

“…Oposto a tal padrão mundial, um aporte exógeno, massivo e persistente, resultante da abertura de um canal artificial (o canal do Valo Grande -VG), vem reduzindo drasticamente as condições estuarinas do ecossistema Estuário Cananéia-Iguape (ECI -sudeste do Brasil; Barrera-Alba et al, 2007;Barcellos et al, 2009;Barrera-Alba et al, 2009;Mahiques et al, 2009;Cunha-Lignon et al, 2011;Coelho, 2011;Mahiques et al, 2012). Apesar desse impacto, o ECI possui proeminente interesse local, regional e global à sua conservação .…”

“…O estudo de colunas sedimentares fornece o registro histórico da acumulação de metais no sistema aquático, indicando tanto os níveis de basais de metais como fontes antrópicas (Ravichandran et al, 1995). Mahiques et al (2013) Borges et al (2007) analisaram Fe, Cu e Pb em três testemunhos em regiões de mangue na Baia de Guanabara. Um dos testemunhos se localizava em uma região onde a vegetação havia sido desmatada há 20 anos, a segunda onde a vegetação havia sido desmatada há dois anos e a terceira com uma vegetação remanescente.…”
