Heavy metals concentrations

Sediment pollution. The concentrations of pollutants in the dated sediment cores have been determined in our laboratory by atomic absorption spectrophotometry (AAS). Donazzolo et al. (15) and Pavoni et al. (16) reported mainly heavy metal concentrations. Marcomini et al. (17) and Pavoni et al. (18) discussed the concentration profiles of organic pollutants such as chlorinated hydrocarbons and polycyclic aromatic hydrocarbons. [Pg.291]

Heavy metal concentrations have been determined in 156 sediment samples disseminated in the Gulf of Venice. The presence of metals has been related to a number of factors (26-31) ... [Pg.293]

We must also consider the consequences of forty years of ecosystem pollution loading. Compared with soil analyses of heavy metal concentrations made in 1965, cadmium, copper, lead and zinc levels are now elevated 24) to the point where laboratory studies have shown that red spruce root and shoot growth is reduced, growth of obligatory mycorrhizal fungi is repressed and... [Pg.369]

Fig. 15-7 Relationship between dissolved and total heavy metal concentrations in several rivers. Cross-hatched bands represent range of values from the Ruhr (Imhoff et ah, 1980) W and F represent winter and fall values at a selected station in the Mississippi (Eisenreich et ah, 1980) Triangles represent values from the Rhine river (Davis, 1984).

This ability to grow in polluted soils and withstand high heavy metal concentrations rests on complex mechanisms involving both avoidance through exclusion of metal ions from the cytoplasm and tolerance of high internal metal concentrations (126), this being often dependent on the induction of specific genes and proteins (126,127). [Pg.284]

Chemical analysis of the Meza River and its tributaries revealed significant heavy metal pollution of the upper Meza River sediments with lead, zinc, and some molybdenum, cadmium and arsenic enrichments. The trend of Cd and As is similar to trend of Pb and Zn, which is in agreement with the fact that Cd and As are associated with Pb and Zn in ore minerals (Strucl, 1984 Fux Gosar, 2007). In the lower Meza valley, these heavy metal concentrations decreased somewhat. [Pg.213]
