The distribution of mercury in sediments of the Patos Lagoon estuary and nearby coastal marine deposits has been investigated for the period 1998–2008. Polluted urban soils and coastal reclamation fills are the principal ...

The whole-sediment Toxicity Identification Evaluation (TIE) approach is a useful technique that allows for the identification of the contaminants responsible for the toxicity of complex sediment samples. This study aimed ...

The rivers, lakes and dam sediment analyses are able to predict the back conditions of these ecosystems and determine how the environment changed as a result of anthropogenic activities. In this way they can be used as ...
