Polycyclic aromatic hydrocarbons levels and potential biomarkers in a native South American marine fish
(Elsevier, 2019-05-29)
Polycyclic aromatic hydrocarbons (PAHs) cause adverse effects on ecosystems and organisms from aquatic environments due to their toxicity, persistence, and bioaccumulation characteristics. Furthermore, PAH exposure in fish ...
Anthropogenic pollution of aquatic ecosystems: Emerging problems with global implications
(Elsevier B.V., 2020-04)
Aquatic ecosystems cover over two thirds of our planet and play a pivotal role in stabilizing the global climate as well as providing a large array of services for a fast-growing human population. However, anthropogenic ...
Vitellogenin and Lipovitellin from the prawn Macrobrachium borellii as hydrocarbon pollution biomarker
(Pergamon-Elsevier Science Ltd, 2012-08)
During reproduction vitellogenin (VTG) is transported to vitellogenic oocytes as a precursor of egg yolk lipovitellin (LV). As VTG synthesis is affected by environmental stressors, it is widely used as biomarker in endocrine ...
Oil spill effects on macrofaunal communities and bioturbation of pristine marine sediments (Caleta Valdés, Patagonia, Argentina): experimental evidence of low resistance capacities of benthic systems without history of pollution
(Springer Heidelberg, 2015-02)
The Patagonian coast is characterized by the existence of pristine ecosystems which may be particularly sensitive to oil contamination. In this study, a simulated oil spill at acute and chronic input levels was carried out ...
Factors driving the abundance and distribution of microplastics on sandy beaches in a Southwest Atlantic seaside resort
(Elsevier, 2021-10)
Microplastics are currently considered widespread marine pollutants, accumulating in sediments and shorelines around the world. Spatial distribution of microplastics in marine sediments is consequence of a combination of ...
A shift of ecosystem engineers during the succession of an intertidal benthic community associated with natural and anthropogenic disturbances
(Elsevier, 2019-07)
Temporal variation and sewage pollution were assessed on the recruitment of two benthic ecosystems engineer species during an experimental succession. The re-colonisation of the spionid polychaete Boccardia proboscidea and ...
A negative feedback between anthropogenic ozone pollution and enhanced ocean emissions of iodine
(Copernicus Publications, 2015-02)
Naturally emitted from the oceans, iodine compounds efficiently destroy atmospheric ozone and reduce its positive radiative forcing effects in the troposphere. Emissions of inorganic iodine have been experimentally shown ...
Isolation of Plant Growth Promoting Rhizobacteria from Spartina densiflora and Sarcocornia perennis in San Antonio polluted salt marsh, Patagonian Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2021-10)
With the purpose of Plant Growth Promoting Rhizobacteria (PGPR) isolation, several authors have sampled different wetlands in the northern half of Argentina. However, to date, we do not know the existence of microbiological ...
Pelagic seabirds as biomonitors of persistent organic pollutants in the Southwestern Atlantic
(Pergamon-Elsevier Science Ltd, 2019-12)
Persistent Organic Pollutants (POPs) are accumulated through time and can exert different effect on ecosystems. POPs and Chlorpyrifos, a current use pesticide, were assessed in body feathers of males and females of ...
First report of microplastics presence in the mussel Mytilus chilensis from Ushuaia Bay (Beagle Channel, Tierra del Fuego, Argentina)
(Pergamon-Elsevier Science Ltd, 2020-12)
Microplastics contamination is reported for the first time on Mytilus chilensis from Ushuaia Bay, one of the most remote areas of South America. Our results demonstrate the occurrence of microplastics in all samples, with ...
