“…In this study, ecological indicators, especially ecological descriptors, trophic categories and size, were especially effective for the demonstration of the critical alterations of the fish community of Zone 1, indicating that the biota is an integrating element that responds systematically to alterations in the environment, despite the restrictions about the use of analysis on the community structure in estuarine environments (Elliott and Quintino, 2007). These impacts were also evident when more sophisticated methods were applied as a selection of fish based multimetric indices of ecosystem integrity (Viana et al, 2012).The cargo terminal and industrial district are a case in point here and in addition to the intrinsic potential risks represented by its industries, a number of accidents have been reported since the installation of its ore-processing plants (Lima et al, 2011). Additionally, Berrêdo et al (2001) showed evidence of contamination by heavy metals in the region.…”

“…These processes produce residues which may liberate substances with significant impacts on the quality of the water (Rubio and Tessele, 2002). The principal sources of risk include leaks from tanks and pipelines, accidental spills of toxic substances and the overflowing of residue sedimentation pools, all of which have been recorded in the study area since the establishment of the industrial installations (Lima et al, 2011).…”

“…A exploração dos recursos naturais em Barcarena evidencia as mudanças em escala social e ambiental, as quais vêm comprometendo a qualidade dos recursos hídricos e, consequentemente, trazendo riscos para as comunidades que moram no entorno do polo industrial 32 , gerando conflitos socioespaciais pela introdução de novos valores na conjuntura socioeconômica local e provocando novos usos e ocupação do solo. Nesse sentido, há necessidade de infraestrutura, mais saneamento básico e mais serviços públicos.…”

“…O vazamento durou cerca de um dia, lançando no meio ambiente 300 mil metros cúbicos de rejeitos usados na produção de caulim. Parte desse material atingiu a estrada que separa a empresa do Bairro Industrial, os igarapés Curuperê e Dendê e suas respectivas áreas de preservação permanente, bem como as praias do Caripi, Conde e Itupanema, tingindo suas águas de branco por uma semana, causando prejuízo aos ecossistemas aquáticos e risco à saúde da população local, que utilizava os rios para consumo, higiene e afazeres domésticos (LIMA et al, 2011 (PARÁ, 2007).…”
