Integrating multiple lines of evidence of sediment quality in a tropical bay (Guanabara Bay, Brazil)
Marine Pollution Bulletin, 2019 The present study evaluated the ecological risk of metal contamination in sediments of Guanabara Bay (GB) by combining multiple lines of evidence (LOEs). Chemical analysis and a set of whole-sediment toxicity assays were conducted with Tiburonella viscana, Kalliapseudes schubartii, Anomalocardia flexuosa, and Nitocra sp.

Virioplankton dynamics are related to eutrophication levels in a tropical urbanized bay. [PDF]
PLoS ONE, 2017 Virioplankton are an important and abundant biological component of marine and freshwater ecosystems. Often overlooked, aquatic viruses play an important role in biogeochemical cycles on a global scale, infecting both autotrophic and heterotrophic ...

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.Abstract Tropical Southeast Asian estuaries remain underrepresented in global water quality archives, limiting regional comparisons and the development of predictive biogeochemical models for monsoon‐driven coastal systems. To address this observational gap, this paper presents a quality‐controlled, 10‐year (2015–2025) biogeochemical data set for the ...

Ecological risk index for aquatic pollution control: a case study of coastal water bodies from the Rio de Janeiro State, southeastern Brazil [PDF]
Geochimica Brasiliensis, 2013 The Potential Ecological Risk Index (PERI) was proposed by Håkan-son in 1980 to be used as a diagnostic tool for water pollution. The aim of this study was to apply the PERI for tropical conditions, proposing modifications.
