Urban activity and mercury contamination in estuarine and marine sediments (Southern Brazil)
(2009)
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 ...
Organic matter redox state driven by specific sources in mangrove sediments: A case study from peruvian ecosystems
(MDPI, 2021)
In order to determine the organic matter redox state in relation to specific sources in mangrove sediments, two 60 cm-long sediment cores were collected from mangrove-covered and mudflat zones within a mangrove forest in ...
Background values, distribution and contamination of metals in the sediments of the Pontevedra Ria (NW Spain)
