Journal ArticleDOI
Bacteriological study of the superficial sediments of guanabara bay, rj, brazil*
Frederico Sobrinho da Silva,Daniella da Costa Pereira,Leonisa Sanchez Nuñez,Natascha Krepsk,Luiz Francisco Fontana,José Antônio Baptista Neto,Mirian Araújo Carlos Crapez +6 more
TL;DR: The input of untreated sewage in the Mangue Channel outflow in Guanabara Bay has favored the increase of the organic load, and the maintenance of the total Coliforms and faecal coliforms in the sediment, which may be an ideal candidate group for sediment quality tests.
Journal ArticleDOI
Determination of water quality, toxicity and estrogenic activity in a nearshore marine environment in Rio de Janeiro, Southeastern Brazil.
Marilia Teresa Lima do Nascimento,Ana Dalva de Oliveira Santos,Louise da Cruz Felix,Giselle Gomes,Mariana de Oliveira e Sá,Danieli Lima da Cunha,Natividade Vieira,Rachel Ann Hauser-Davis,José Antônio Baptista Neto,Daniele Maia Bila +9 more
TL;DR: Estrogenic activity was most frequently observed in samples from the bottom of the water column, indicating adsorption of estrogenic compounds to the sediment, and water quality was mostly within the limits established for marine waters by the Brazilian legislation.
Journal ArticleDOI
Ecological risks of trace metals in Guanabara Bay, Rio de Janeiro, Brazil: An index analysis approach.
Valquiria Maria de Carvalho Aguiar,Michelle Nunes de Lima,Rodrigo Coutinho Abuchacra,Paula Ferreira Falheiro Abuchacra,José Antônio Baptista Neto,Heloisa Vargas Borges,Vitor Calôr de Oliveira +6 more
TL;DR: Results effectively revealed the striking contamination in Guanabara Bay concerning trace metals, and also suggested potential risk to local biota.
Journal ArticleDOI
Environmental change in Guanabara Bay, SE Brazil, based in microfaunal, pollen and geochemical proxies in sedimentary cores
José Antônio Baptista Neto,Cintia Ferreira Barreto,Claudia Gutterres Vilela,Estefan Monteiro da Fonseca,Gustavo Vaz de Melo,Ortrud Monica Barth +5 more
TL;DR: In this article, the authors investigated the environmental change in the last decades using recent sediments cores along the coastal area of Guanabara Bay and found high concentrations of metals (Pb, Ni, Cu, Cr, Zn and Mn) were observed in the three sediment cores over approximately the last hundred years.
Journal ArticleDOI
Geochronology and heavy metal flux to Guanabara bay, Rio de Janeiro state: a preliminary study
José Antônio Baptista Neto,Tomas C.S. Peixoto,Bernard Smith,J. J. McAlister,Soraya Maia Patchineelam,Sambasiva R. Patchineelam,Estefan Monteiro da Fonseca +6 more
TL;DR: The organic carbon and heavy metals flux started to increase at the beginning of the last century and the highest values was observed in the top of the cores, which gave a calculated net average sedimentation rate for the core of 0.67 cm.
