Estuarine pollution imposes rapid, increasing and lasting environmental modifications. In the
present review, especial attention is given to estuaries in South America (SA), where …

Research on estuarine ecology in South America (SA) increased quali-quantitatively since
the early 1980 in search of consistent recommendations for estuarine conservation. The …

Abstract The concentrations of As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Sr, and Zn were analyzed

This work aimed to evaluate the use of Mugil curema as a biomonitor for polycyclic aromatic
hydrocarbon (PAH) bioavailability. Fish biliary metabolites from low-contaminated …

The Cananéia-Iguape estuarine–lagoon complex (São Paulo state, Brazil) is a natural
laboratory to study metal binding by humic substances (HS) in subtropical settings. This …

Although metallic elements occur naturally, they can occur or accumulate in organisms at
levels toxic to the organism and/or their consumers. Concentrations of twenty-nine metallic …

Metals occur naturally in the environment and in organisms. Organisms at higher trophic
levels may contain metals at elevated concentrations, as a result of accumulation from …

Particle induced X-ray emission (PIXE), a well established method for elemental analysis,
was used to evaluate the levels of trace elements in blood serum samples of tongue cancer …

The present paper reviews information about sources, fate, concentrations and toxicity of the
metals found in the Cananéia-Iguape Estuarine Complex (CIEC), which is within a Ramsar …
