Arsenic exists in a variety of chemical forms, and microbial metabolism results in the
occurrence of thermodynamically unstable arsenite (AsIII) and methylarsenic compounds in …

In this concept paper, some basic problems in the obtaining of the dissolved organic matter
(DOM) are described. Some of them are fairly obvious such as adsorption and desorption on …

The magnitude and ecological relevance of metal pollution of the middle Po river deriving
from the River Lambro tributary was investigated by applying different (complementary) …

In the present study, trace metals contents (V, Cr, Mn, Fe, Ni, Cu, Zn, Cd and Pb) and
physico–chemical parameters (nitrogen, organic and inorganic carbon, pH and particle size) …

The pollution of aquatic ecosystems by heavy metals has assumed serious proportions due
to their toxicity and accumulative behavior. River dams are especially at risk of …

A better understanding of the relationships between heavy metal pollution and sediment
sources in different aquatic environments is needed. In this study, some geochemical …

The role of ultramafic rock weathering in global chromium (Cr) budgets and how these may
be linked to changes in Earth's climate over geological time was investigated by compiling …

Grain-size distribution, major elements, nutrients and trace metals were determined in bed
sediments and suspension collected at 10 representative sites along the river Po under …

With the goal of improving understanding of the effect of flocculation on the formation of fine-
grained deposits on continental shelves, hydrographic profiling, in situ imaging of …

Concentrations of dissolved and particulate organic carbon (DOC, POC) and particulated
nitrogen (PN) were measured in samples taken monthly for a year at two stations in the …
