Organic markers of sewage contamination in surface sediments from Santos bay, São Paulo [PDF]

, 2008
Organic markers, such as sterols and ketones, were used to assess sewage contamination in sediments from the Santos Bay, SP, and its continental shelf. These compounds were analyzed by GC/FID after soxhlet extraction, clean up and derivatization.

Ecological risk evaluation of sediment metals in a tropical Euthrophic Bay, Guanabara Bay, Southeast Atlantic [PDF]

Marine Pollution Bulletin, 2016
Surface sediments were collected from Guanabara Bay, at 14 stations distributed in five sectors, over three sampling campaigns. Analyses of metals, grain size fractions and total organic carbon analyses were performed. The geo-accumulation index and the enrichment factor were estimated to assess contamination status based on background values ...

Massive Blooms of Chattonella subsalsa Biecheler (Raphidophyceae) in a Hypereutrophic, Tropical Estuary—Guanabara Bay, Brazil

Frontiers in Marine Science, 2019
Cell concentrations of the potentially harmful raphidophyte Chattonella subsalsa Biecheler were quantified in surface waters of Guanabara Bay, a heavily eutrophicated estuarine system in tropical Brazil, from February 2014 to January 2018.

Supporting decision‐making on urban flood control alternatives through a recovery deficit procedure for successive events

Journal of Flood Risk Management, Volume 13, Issue 2, June 2020., 2020
Abstract The occurrence of floods poses a challenge to cities, resulting in tragedies and losses in watersheds unprepared to receive massive amounts of water. Therefore, studies to define impacts caused by successive flood events are essential to quantify long‐term losses and allow feasibility analysis of design alternatives to mitigate them.

Bacterioplankton community variation in Bohai Bay (China) is explained by joint effects of environmental and spatial factors

MicrobiologyOpen, Volume 9, Issue 4, April 2020., 2020
Parsing the relative importance of environmental and spatial factors in determining community structure in anthropogenic disturbed semi‐enclosed bay environment is rarely few. This study found that the joint effects of environmental and spatial factors contributed to the explained variation of bacterioplankton community composition in Bohai Bay (China),
