“…Use of a single value, regardless of the spatial variations could give rise to either overestimation or underestimation of metal contamination and the associated risk. Nevertheless, it is important to assess the background concentration which is essential for risk assessment and regulation of metals in water/soil systems (Wendland et al 2005;Zhao et al 2007;Marandi and Karro 2008;Vencelides et al 2010). In the analyses of soil geochemical data, the relationship of selected elements with Fe or Mn has been used to estimate their background concentrations assuming that the soils in a sub-set from remote areas were uncontaminated.…”

Selected trace metals were estimated by atomic absorption spectrometry in the water and soil samples collected from the remote region of Himalaya. The soil samples were analysed for soluble and acid extractable fraction of trace metals. In water samples, Ca, Na, Mg and K emerged as dominant contributors, whereas, Ca, Na, K, Mg, Fe and Pb were estimated at comparatively higher levels in the water extract of the soil. In case of acid extract of the soil samples, Ca, K, Fe, Mg, Mn and Na were found at elevated concentrations. Based on mean levels of the metals, following decreasing concentration order was observed in water samples: Ca > Na > Mg > K > Pb > Co > Cu > Zn > Mn > Cr > Fe > Cd > Li, however, in the acid extract of the soil, following order was noted: Ca > K > Fe > Mg > Mn > Na > Pb > Zn > Cr > Li > Cu > Co > Cd. The correlation study revealed appreciably diverse mutual relationships of trace metals in the water and soil samples. The multivariate cluster analyses exhibited divergent apportionment of trace metals in water and soil samples. Among the trace metals, Cd, Pb, Li, Zn, Cr, Cu, Mn and Co exhibited extreme to significant anthropogenic enrichment in the soil samples, while the rest of the metals were mostly contributed by the natural processes.

“…Analysis of its impact on the chemistry of ground waters in the Czech Republic is difficult because of the lack of sufficient and reliable data. The study and determination of the natural background of selected metals in ground waters was carried out in 2006-2009, and the results achieved and methods of data processing were described in detail in a paper by Vencelides et al 2010, which we refer to for detailed information on the subject. From this publication we pick out only a brief summary of basic principles and data to the extent necessary for understanding the method for assessment of the possible effect of atmospheric deposition on the natural background of certain metals in ground waters.…”

“…In harmony with these requirements the natural backgrounds of selected metals were established within the project "An overview of toxic elements and their anomalies in the Labe River catchment" undertaken in [2006][2007][2008][2009], and financed by the Ministry of Environment of the Czech Republic (Vencelides et al 2010).…”

In harmony with requirements of Water Framework Directive the natural backgrounds of selected metals were established on the territory of Czech Republic. This paper is intended to provide characteristics and results of testing methods focused on quantification of the impacts of anthropogenic activities based on data of regional monitoring and their separation from acid atmospheric deposition including an appropriate discussion regarding the natural backgrounds of relevant metals. The results indicate that even in regions extremely affected by acid atmospheric deposition as is the territory of the Czech Republic this acid deposition will not have direct impact on the quality of ground waters on a regional scale. Consequently, the proved changes in quality of ground waters seem to have been caused by secondary processes, specifically by mobilization of metals in a rock environment due to increased acidity.
