Autor: Renata Hanae Nagai, Silvia Helena de Mello e Sousa, Rafael André Lourenço, Márcia Caruso Bícego, Michel Michaelovitch de Mahiques
Publikováno v: Brazilian Journal of Oceanography, Vol 58, Iss spe1, Pp 31-41 (2010)
Changes in the Brazilian continental margins oceanic productivity and circulation over the last 27,000 years were reconstructed based on sedimentological and microfaunal analyses. Our results suggest that oceanic paleoproductivity and the supply of t

O destino de grande parte da matéria orgânica presente nos oceanos é o sedimento marinho. Essa matéria orgânica, que vai sendo armazenada ao longo dos anos, produz uma reserva única de informações sobre os processos biogeoquímicos ocorridos

Can the environmental health of urban centers be assessed through pollutants trapped in lakes? A study case in the biggest city of the southern hemisphere
Autor: Rafael André Lourenço, Josilene da Silva, Satie Taniguchi, Julia Blanco
Publikováno v: Environmental Science and Pollution Research. 28:30774-30782
Air and water quality in urban centers are summited to pollution from different sources, such as industrial activities, traffic, and wastewater effluents. A great number of chemicals can be spread by wind throughout the city, exposing the inhabitants

Levels of hydrocarbons and toxicity of water-soluble fractions of maritime fuels on neotropical invertebrates
Autor: Debora Cristina Nascimento, de Santana, Fernando Cesar, Perina, Rafael André, Lourenço, Josilene, da Silva, Lucas Buruaem, Moreira, Denis Moledo, de Souza Abessa
Publikováno v: Ecotoxicology (London, England). 30(10)
Accidents involving fuels and oil spills are among the main sources of hydrocarbons to the marine ecosystems and often damage the biota. Diesel and bunker oil are two examples of fuels with broad application that release hydrocarbons to the aquatic e

Morphological, structural and compositional alterations in shells of molluscs have been proposed as putative biomarkers of chemical contamination in coastal zones. Despite this, few studies were carried out using top predator gastropods which tend to
