“…The high percentage of lead in the acid soluble fraction indicates its recent origin possibly due to increasing vehicular traffic in the city (Adami et al, 2007). The dominance of lead in the acid soluble phase is also reported in the sediments of the Tisza River, Serbia (Sakan et al, 2009). Moreover, the high concentration of Pb in the acid soluble fraction in the sediments is in accordance with its special affinity for carbonates.…”

In this study, the fractionation and ecotoxic potential of Cr, Ni, Cu and Pb in water and sediments of the river Yamuna (Delhi stretch) is presented. The river water is used for various purposes such as irrigation, industrial, domestic and drinking. The investigations suggest that the availability of metals in water follows the sequence Ni>Cr>Pb>Cu whereas a different pattern (Pb>Cu>Ni>Cr) is observed in sediments. Statistically significant spatial variations are indicated by two-way ANOVA in different geochemical forms of the metals and physicochemical parameters of water and sediments of the river Yamuna. Principal component analysis (PCA) suggests a similar source for all four metals probably from the sewage from municipal drains. PCA also indicates some independent sources of Cu and Pb. The hot spots were identified using hierarchical cluster analysis considering bioavailable forms of the metals in water and sediments as objects and the sampling sites as variables. Risk assessment code analysis indicates that metals generally pose medium to high risk at different sites. However, at a few locations either Ni or Pb cross the level of very high ecological risk.

“…Heavy metal level higher than twice the background implies anthropogenic pollution, while EF higher than 2 indicates contamination (4,(18)(19)(20). The enrichment of heavy metals in sediment is mainly due to surface adsorption and ionic attraction (21).…”

The aim of this study was to establish microbial and heavy metal pollution of the Sava River at three locations close to industry and urban areas (Šabac, Obrenovac, Beograd) in Serbia. Heavy metal analysis included Cu, Zn, Pb, and Cd in the river water and sediment samples. Using the microbiological analysis we tried to establish the effectiveness of total coliforms, faecal coliforms and Escherichia coli in detecting pollution of surface waters. We found that E. coli levels steadily increased downstream from Šabac (location 1; 2100 MPN per 100 mL) to Belgrade (location 3; 10000 MPN per 100 mL). To prevent bacterial contamination, it is necessary to reduce the discharge of wastewater with faecal matters near highly populated towns. Heavy metal levels in sediments correlated with those in the river water. Fluctuations attributed mainly to anthropogenic sources were not high. These results point to acceptable anthropogenic contribution to heavy metal content in the Sava River and to low environmental risk.

“…In the absence of data relating to the local trace metal background values, this study uses those reported for the continental shale [29]. Sakan et al [30] suggested that EF values <1 indicate no enrichment; <3 indicate minor enrichment; 3-5 indicate moderate enrichment; 5-10 indicate moderately severe enrichment; 10-25 indicate severe enrichment; 25-50 indicate very severe enrichment; and >50 indicate extremely severe enrichment. In order to get insights into possible inter-dependence between the hydrodynamic conditions (in terms of FT) and the trace metal EF values, a Pearson's correlation analysis was performed.…”

Water renewal time and trace metal concentration in civitavecchia port (rome), italy

Most of the harbours can be considered as semi-enclosed areas where water stagnation leads to physical and chemical alterations due to anthropogenic activities. These features affect the quality of the port waters as well as the environmental health of coastal ecosystems in the surrounding areas. In order to understand the potential degradation of water quality within the harbour area it is essential to evaluate the hydrodynamic behaviour of the system. In this study, the DELFT3D-FLOW model, which allows to estimate the three-dimensional field velocity, was used to spatially characterize the water renewal time within the harbour. In particular, the flushing time (FT), which represents the time required for the total mass of a conservative tracer originally within the water body to be reduced to a factor 1/e, was examined. The concentration of contaminants in sediments is indeed a proper parameter to test the reliability of the calculated water renewal time within the semi-enclosed basins, since it relies on time-integrated measurements compared to single observations of water column. This research aims at studying the relation between the FT and the pollution due to trace metals in marine sediments. For this purpose, surface sediment samples were collected along a series of stations located in the innermost part and near the mouth of the Civitavecchia harbour. As, Cr, Hg, Ni, Cu, zn, Pb and Al concentrations were analysed to calculate the enrichment factor, which provides an estimate of the heavy metal contamination in the harbour surface sediment. The obtained results show a high correlation between the FT and the enrichment factor within the Civitavecchia port, confirming that water renewal can be used as an indicator of water quality degradation in semi-enclosed areas.
