Abstract The Rodrigo de Freitas Lagoon (RFL-Rio de Janeiro, RJ, Brazil) is a highly polluted
and eutrophic lacustrine system, which has been often used for the practice of aquatic …

The sediment contamination by trace metals in coastal aquatic ecosystems is a worldwide
environmental problem, since metals can be toxic, persistent, and bioaccumulated. In case …

Urban tropical lagoons are often impacted by eutrophication, metal, and polycyclic aromatic
hydrocarbon (PAH) contamination, but the toxicity of their bottom sediments is still poorly …

The present study evaluated the ecological risk of metal contamination in sediments of
Guanabara Bay (GB) by combining multiple lines of evidence (LOEs). Chemical analysis …

The resuspension of polluted sediments often transfers contaminants to the water column,
but the potential alterations in deposited bottom sediments remain overlooked. Guanabara …

Purpose Dredged sediments are often disposed on land areas and can cause adverse
effects on soil biota, since these materials generally may contain toxic agents. This work …
