Matching metal pollution with bioavailability, bioaccumulation and biomarkers response in fish (Centropomus parallelus) resident in neotropical estuaries
(Elsevier, 2013-06)
Two neotropical estuaries affected by different anthropogenic factors were studied. We report levels of metals and metalloids in water and sediment as well as their influence on genetic, biochemical and morphological ...
A baseline study of microplastics in the burrowing crab (Neohelice granulata) from a temperate southwestern Atlantic estuary
(Pergamon-Elsevier Science Ltd, 2020-01)
Growing evidence has demonstrated that microplastics (MPs) are available for a wide range of marine organisms, with filter-feeding bivalves and crabs being especially vulnerable. The crab Neohelice granulata is considered ...
Biomarker responses and PAH ratios in fish inhabiting an estuarine urban waterway
(2017-10-01)
Many cities worldwide are established adjacent to estuaries and their catchments resulting in estuarine contamination due to intense anthropogenic activities. The aim of this study was to evaluate if fish living in an ...
Industrial waste as a source of surface and groundwater pollution for more than half a century in a sector of the Río de la Plata coastal plain (Argentina)
(Pergamon-Elsevier Science Ltd, 2018-09)
Environmental liabilities have become one of the most important problems of the last years, especially those of contaminated sites located in urban areas which have been abandoned by pollution intensive industries. Such ...
Santos estuarine sediments, brasil-metal and trace element assessment by neutron activation analysis
(Sao Paulo: ABEN, 2009, 2014)
Environmental modulation of the plankton community composition and size-structure along the eutrophic intertidal coast of the Río de la Plata estuary, Argentina
(Page Press, 2014-05)
In this study we investigated the spatial distribution of the plankton community, bacterio-, phyto-, and zooplankton, in relation with environmental conditions along the intertidal coast of the Río de la Plata estuary, ...
Biogeochemical markers across a pollution gradient in a Patagonian estuary: A multidimensional approach of fatty acids and stable isotopes
(Pergamon-Elsevier Science Ltd, 2018-12-29)
A combined approach merging stable isotopes and fatty acids was applied to study anthropogenic pollution in the Río Negro estuary. Fatty acid markers of vegetal detritus indicated considerable allochthonous inputs at ...
Microplastics in the Digestive Tracts of Four Fish Species from the Ciénaga Grande de Santa Marta Estuary in Colombia
(Springer, 2019-11-05)
This study investigated the presence of microplastics (MPs) in the gastrointestinal tracts of four fish species from the estuarine Ciénaga Grande de Santa Marta (CGSM) in northern Colombia. Of the 140 fish purchased at a ...
