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 ...
Mercury dispersal to arroyo and coastal sediments from abandoned copper mine operations, El Boléo, Baja California
(Bulletin of Environmental Contamination and Toxicology, 2009)
Evidence for mercury dispersal in an arid coastal region of central Baja California (Mexico) suggests that abandoned copper mining operations are a noticeable source of mercury in the environment. There is a generally ...
Sedimentation rates by the 210Pb chronological method in Itanhaém river watershed, southeast Brazil
(2021-12-01)
The historical variation of sedimentation rate was investigated in five cores collected from the Itanhaém watershed main rivers, the second largest coastal watershed of the São Paulo state, Brazil, using the lead-210 ...
Effect ofplankton-derivedorganic matter on themicrobial community of coastal marine sediments
(Amsterdam, 2014-08-17)
An experimental study was carried out to observe the microbial response to two different plankton-derived organic matter inputs in a coastal sedimentary community of Ubatuba, São Paulo, SE Brazil. The organic enrichment ...
Effects of harbor activities on sediment quality in a semi-arid region in Brazil
(2017-01-01)
Tropical marine environments are rich in biodiversity and the presence of harbor activities in these areas can harm the coastal ecosystems. In this study, we assessed sediment quality of two harbors from a tropical region ...
Abundance, dynamics, and biogeographic distribution of seven Polycyclic aromatic hydrocarbon dioxygenase gene variants in coastal sediments of Patagonia
(American Society for Microbiology, 2012-02)
Novel polycyclic aromatic hydrocarbon dioxygenase gene variants were present in abundances similar to or higher than those of phnA1 from Cycloclasticus spp. at a chronically polluted subantarctic coastal marine environment ...
Anthropogenic and authigenic uranium in marine sediments of the central Gulf of California adjacent to the Santa Rosalía mining region
(Archives of Environmental Contamination and Toxicology, 2012)
To investigate the causes of uranium (U) enrichment in marine sediments in the eastern sector of the Gulf of California, surface sediments and sediment cores were collected adjacent to the Santa Rosalı´a copper mining ...
