Estuarine systems are vulnerable to metals stress, such as copper (Cu). Thus, the development of applicable tools improve routine monitoring programs is increasingly necessary. In present work a comprehensive Ecological Risk Assessment (ERA) was implemented by coupling Measured Environmental Concentration (MEC), based on labile Cu (DGT) and total dissolved concentration. Additionally, toxicity data related site-specific Predicted No Effect (PNEC) were used. As case study, estuarine areas...
Abstract: Aim This study aimed to evaluate the Trophic State Index (TSI) at margin and in channel of Patos Lagoon estuary, considering different hydrological conditions. Methods Surface bottom water samples were collected three sites (margin center) two Saco da Mangueira conditions 2011. Results Waters are very contaminated by phosphate nitrogenous compounds. The TSI classifies these waters as being hypereutrophic, consequence both release effluents which poorly treated low flow inlet....
The southern area of the Patos Lagoon estuary has been subjected to intense industrial and port-related activities which have not only caused meaningful changes in landscape but also degraded aquatic resources by contaminating them with dissolved nutrients trace metals last decades.This study aims at compiling data on development that happened urban occupation Rio Grande, a city located south Grande do Sul, RS, Brazil, relating it main results contamination indicators estuarine environment...
The diffusive gradients in thin-films (DGT) technique was used to determine labile metals situ during different hydrological conditions the Patos Lagoon estuary. Water samples were also analyzed for Chelex-labile fractions of Cd, Co, Cu, Mn, Ni and Zn using Chelex-100 resin. DGT-labile concentrations lower than concentrations, possibly because colloids trapped Chelex resin column. There a decrease with increasing deployment time all elements measured by DGT, reflecting changes metal...

The Rio Grande Channel, in the area of Port Grande, receives direct and indirect contributions trace metals, which can compromise quality estuarine waters lagoon. In this study, data metals studies from monitoring program port estuary, 1996 to 2001, were interpreted. objective was evaluate distribution cadmium, copper, lead zinc concentrations total fraction surface along area, areas known as Porto Novo, Superporto São José do Norte located at Canal. results showed that only cadmium...
Copper and zinc are common elements in paint residues can be toxic to estuarine organisms. This study aims determine the labile dissolved particulate fractions (LPFs) of copper waters a shipyard southern Brazil under different salinity levels seasons. The fraction was determined using diffusive gradient thin-film (DGT) technique. variations DGT-Cu (0.22-1.05 µg L-1), DGT-Zn (0.54-18.39 LPF-Cu (1.22-3.77 g-1), LPF-Zn (4.29-19.12 g-1) concentration were related changes their physico-chemical...
