Publikováno v: SSRN Electronic Journal.

The Iguaçu River basin presents high ecological importance due to its expressive endemic ichthyofauna rate, but chemical pollution may threat this biodiversity. Jordão River is one of the main tributaries of Iguaçu River and contribute to this pol

Sources and distribution of biomarkers in surficial sediments from a polar marine ecosystem (Potter Cove, King George Island, Antarctica)

Autor: César Castro Martins, Ana Lúcia Lindroth Dauner, Edgardo A. Hernández, Walter Patricio MacCormack

Publikováno v: Polar Biology. 40:2015-2025

Sedimentary organic matter (OM) represents the energy supply for the shelf benthos at the Antarctic Ocean, and has yet to be properly characterized in terms of sources and composition for the Potter Cove region, King George/25 de Mayo Island. This en

A critical and comparative appraisal of polycyclic aromatic hydrocarbons in sediments and suspended particulate material from a large South American subtropical estuary

Autor: Ana Lúcia Lindroth Dauner, César Castro Martins, Fernanda D. Cardoso

Publikováno v: Environmental Pollution. 214:219-229

The Paranaguá Estuarine Complex (PEC) is an important socioeconomic estuary of the Brazilian coast that is influenced by the input of pollutants like polycyclic aromatic hydrocarbons (PAHs). Because of the apparent lack of comparative studies involv

Publikováno v: Chemosphere. 251:126435

Sedimentary sterols and linear alkylbenzenes associated with allochthonous organic matter (AOM) inputs were studied in surface sediments along the Tubarão riverbed, South Brazil. These markers were analysed in terms of concentrations, diagnostic rat

Cluster analysis for time series based on organic geochemical proxies

Autor: César Castro Martins, Ana Lúcia Lindroth Dauner, Márcia Caruso Bícego, Gesine Mollenhauer

Publikováno v: Organic Geochemistry. 145:104038

Depositional and paleoenvironmental studies using organic geochemical proxies often present the temporal evolution of several compounds. Despite the importance of using several proxies to understand how the surrounding environment changed through tim
