“…This can be supported by the fact that the concentrations of heavy metals were the highest in site W1 that was the closest to the outlet. Due to the dilution of river water and absorption of sediment (Vdović et al 2006), the levels of Cu, Cr, and Ni decreased dramatically from sites W1 to W7.…”

Water, paddy soil, and rice from the studied area have been contaminated by Cu, Cr, and Ni. The contamination of these elements is related to the electroplating wastewater. Although no single metal poses health risks for local residents through rice consumption, the combination of several metals may threaten the health of local residents. Cu and Ni are the key components contributing to the potential health risks.

“…This can be supported by the fact that the concentrations of heavy metals were the highest in site 1 that was the closest to the discharge site, as we would expect. Subsequently, the concentrations of heavy metals were dispersed by river water or absorbed by sediments [20], as the alkaline pH of river water facilitate the formation of heavy metal precipitation. Therefore, the levels of heavy metals decreased dramatically from site 1 to site 2.…”

“…Recently, the extent of metal contamination in surface sediments from the contaminated zone of Deûle river was examined (Boughriet et al 2007a;Boughriet et al 2004Boughriet et al , 2007bVdovic et al 2006). It was shown that: (i) overall the pollution of these sediments by metals such as Cd, In, Pb, Sn, Tl and Zn is clearly apparent, increases in the plant proximity, and exceeds the background level; and (ii) metal-rich sediment deposits constitute a potential long term source of pollution as a result of eventually increasing physical disturbances and/or changes in biogeochemical conditions (Boughriet et al 2007b).…”

Using ICP-AES and ICP-MS, several metals were analyzed in water and suspended particulate matter (SPM) samples collected under normal turbidity conditions at various stations from Deûle river (in northern France) to assess the impact of a former smelting plant on the fate of particulate elements and on the water quality in this aquatic environment. Compared to their regional background, particulate Pb, Zn and Cd were found to be most enriched, suggesting anthropogenic inputs from bed sediments into the water column mainly due to physical disturbances induced by barges traffics. Conversely, no significant enrichments of particulate metals such as Cu, Cr and Ni were observed in Deûle SPM. Characterization of SPM with analyses of mineralogical and chemical compositions-using environmental scanning electron microscopy equipped with an energy dispersive X-ray spectrometer (ESEM/ EDS)-indicated the presence of micro-specimens attributed to anthropogenic minerals, mostly PbS and ZnS. The calculated enrichment index (or the geoaccumulation index, I geo ), enrichment factor (EF) and the partition coefficient (K d ) confirmed that SPM was strongly polluted in cadmium, lead and zinc, moderately polluted in copper and unpolluted in chromium and nickel. Based on the analytical data obtained for SPM from the BCR (European Community Bureau of Reference) sequential extraction scheme, it was concluded that: (i) the reducible phases were largely more important for the binding of Pb and Cd than that of Zn and Ni and in a lesser extent Cu and Cr; (ii) copper was found to be mostly associated with the sulphides/ organics fraction; (iii) chromium with a lithogenic origin was extracted in the largest percentage in the residual phase; and (iv) zinc was bound to the exchangeablecarbonate phase in the largest percentage in the particles analysed, followed by nickel and cadmium, suggesting that these metals might be easily remobilized if changes in environmental conditions would occur.
