1. Dredging impact on trace metal behavior in a polluted estuary: a discussion about sampling design
ABSTRACT Studies involving coastal sediment resuspension have shown that trace metals could be released to the water column due to changes in physical-chemical conditions. Therefore, if environmental agencies adopt screening protocols with insufficient evaluations of contaminant mobilization risks for a given area, the prediction of environmental impacts cau

2. Distribution and Sources of Aliphatic and Polycyclic Aromatic Hydrocarbons in Surface Sediments of Itajaí-Açu Estuarine System in Brazil
The Itajaí-Açu estuarine system, located in southern Brazil, has great economic importance due to the presence of two ports (Itajaí and Navegantes). This system is affected by industrial and dredging activities, which can cause the remobilization of pollutants accumulated over time in the sediment. In this context, hydrocarbons were assessed in twelve sur

4. Avaliação da qualidade do sedimento do baixo estuário do rio Itajaí-Açu (SC) através de testes de toxicidade crônica
After CONAMA resolution 344 of 2004, environmental agencies have required the quality assessment of the aquatic environments sediments that are subject to remobilization by dredging activities, mainly in port areas. By toxicity tests of embryo-larval development of sea urchin Arbacia lixula, this study analyzed the spatial-temporal quality variation of Itaja

5. Qualidade da água e distribuição espacial de foraminíferos bentônicos em estuários das Baías Norte e Sul da Ilha de Santa Catarina (Brasil)
Watersheds with different characteristics lead to different rates of biogeochemical elements that contribute in estuarine systems. Thus, this study investigated the contribution of drainage on the nutrients as well as the responses of benthic foraminifera, with focus on estuarine region of six major systems that discharge in the North and South bays of Santa

6. Integrated environmental assesment of Santos estuarine system s disposal site and adjancent zones / Diagnostico ambiental integrado da area de influencia do descarte do material dragado do estuario de Santos
The Atlantic Forest coastal plain which surrounds the city of Santos in the State of São Paulo, Brazil, has a great economic importance, principally due to the port of Santos, the largest in Latin America, and the Cubatão industrial complex. The regions estuary has been polluted by multiple contaminant sources for decades, due to industrial, portuary and

7. Análise quali-quantitativa da carcinofauna da enseada do Saco dos Limões, Baía-Sul, Florianópolis, SC e os impactos decorrentes da construção da Via Expressa SC-Sul
Coastal areas as ponds, bays and estuaries, are usually characterized by presenting a high productivity, working as important reproduction and growth areas for a variety of organisms. The crustaceans represent an important group, transferring the energy for superior levels, besides they contribute in the artisanal and industrial fisheries. Aiming to evaluate

8. Variação espaço-temporal do zooplâncton do baixo estuário do Rio Itajai-Açu, SC
The Basin of the Itajaí-açu River is the largest of Santa Catarina State, Southern Brazil, extending 15,111 Km2 and encompassing the states main industrial zone. Next to the river mouth lays the Itajaí Harbor, which is the principal outlet of international trading of the state and one of the main harbors of the country. The estuarine region aggregates sed

9. Study of Polychaeta associations in Santos Bay and Adjacent Continental Shelf (SP, Brazil) and their interrelations with physical and geochemical patterns / Estudo das associações de anelídeos Polychaeta da Baía de Santos e Plataforma Continental Adjacente (SP, Brasil) e suas interrelações com parâmetros físicos e geoquímicos estruturadores
The aim of the present work was to verify the spacial and vertical Polychaeta distribution in sediment samples of Santos Bay and adjacent continental shelf by analyzing physicochemical characteristics, granulometric pattern, chemical compounds concentration and metallic elements. Parallely, it looked for determining the organic matter origin by C/N/S content
