Science of the Total Environment, 2012
The present study investigated organochlorine compound levels (PCBs, DDTs and HCB) in blubber samples of six delphinid species from Rio de Janeiro State, southeastern Brazilian coast. The species analyzed inhabit the continental shelf (one killer whale, one false killer whale, two bottlenose dolphins, three rough-toothed dolphins, and four long-beaked ...

Journal of Experimental Marine Biology and Ecology, 2001
This work reports the results of a screening program based on marine sponge extracts from the southeastern Brazilian coast, covering cytotoxic and neurotoxic activities. Polar and non-polar extracts of 24 sponge species collected by scuba diving in rocky shores, from 1996 to 2000, were screened for haemolytic, cytotoxic and neurotoxic activities. Fifty-

Saccocirridae (Annelida) from the southern and southeastern Brazilian coasts
Marine Biodiversity, 2014Pharyngocirrus gabriellae (Du Bois-Reymond Marcus 1946) and Saccocirrus pussicus Du Bois-Reymond Marcus 1948 are redescribed based on newly collected material from the south and southeastern Brazilian coasts. Neotypes are designated, since no type material was formally indicated in the original descriptions.

Geological provenance of Quaternary deposits from the southeastern Brazilian coast
Nuclear Physics A, 2007Natural gamma radiation measurements of beach sand deposits were performed with the aim of understanding the provenance and transport processes of sediments along the coastal zone of three Brazilian States. The method employs thorium, uranium and potassium as tracers of the mineralogical properties of beach sand minerals, which reflect the geological ...

Provenance and Transport Processes of Sediments along the Southeastern Brazilian Coast
AIP Conference Proceedings, 2008Natural gamma radiation measurements of Quaternary sedimentary deposits were performed with the aim of understanding the provenance and transport processes of sediments along the coastal zone of the Brazilian Southeast. The method employs thorium, uranium and potassium as tracers of the mineralogical properties of beach sand minerals, which reflect the

Marine Pollution Bulletin, 2021
Among the various pollutants released into the environment, there are persistent organic pollutants (POPs). Chelonia mydas are one of the species that can be exposed to these pollutants and it is classified in the IUCN Red List as "endangered". The present study evaluated the occurrence of POPs in 49liver tissue samples of C.

Rogue waves off the south/southeastern Brazilian coast
Natural Hazards, 2016The occurrence of freak waves off the Brazilian coast was investigated through the analysis of data recorded by three buoys deployed in the south/southeast region, at a depth of 200 m. As well documented in the literature, these events are not rare, and more than 700 waves could be classified as abnormal based on the relation between the maximum wave ...

PCB and PBDE levels in a highly threatened dolphin species from the Southeastern Brazilian coast
Environmental Pollution, 2016In the Northern coast of Rio de Janeiro State is located the major urban centers of the oil and gas industry of Brazil. The intense urbanization in recent decades caused an increase in human use of the coastal areas, which is constantly impacted by agricultural, industrial and wastewater discharges.

The aim of this study was to assess whether all Penaeoidea shrimps captured by trawling are protected by the current closed season. We investigated the reproductive period and juvenile recruitment of Penaeoidea shrimp species captured in the bay-estuary complex of Santos and São Vicente from May 2008 to April 2010.
