Abstract 'Background'is the concentration of metals in pristine sediment, unaltered by human
activity and 'enrichment'is the extent present-day sediment metal concentrations exceed pre …

The accumulation of organic pollutants (pesticides, PCBs, DDT…) and heavy metals (Cd,
Pb, Se, As…) in the aquatic systems can cause serious problems on environment and …

The term" background" is discussed and a definition is suggested to put an end to the
currently unsatisfying (non-) definition of geochemical or natural background. Based on the …

Several environmental indicators were used to evaluate the water and sediment quality of
Ismailia Canal for heavy metal contamination. The average concentrations of heavy metals …

Seasonal variation in the contents of different metals (Al, Cr, Cu, Fe, Mn, Ni and Zn) in two
genera of macroalgae, Ulva and Enteromorpha, was studied at 22 sites on the northwest …

The sorption and desorption of Cu and Cd by two species of brown macroalgae and five
species of microalgae were studied. The two brown macroalgae, Laminaria japonica and …

Although native macroalgae have been used for biomonitoring purposes since the 1950s, a
standardized protocol that would enable widespread implementation of the technique has …

Two long sediment cores were sampled at the Ferrol Ria (Galicia, NW Spain) and the heavy
metal (Co, Cr, Cu, Fe, Ni, Pb and Zn) concentrations measured in order to (i) state accurate …

Groundwater status in highly urbanized areas is particularly affected by anthropogenic
influence due to diffuse pollution deriving from many sources. This makes very often …

The determination of background levels of trace metals in soils and sediments is a key point
for the proper assessment of pollution degree. This study demonstrates the suitability of …
