“…Co, Cu, Mn, Ni, SiO 2 and Zn; Fig. 3) were within the range of concentrations reported for ground waters from the Iberian Pyrite Belt by Pauwels (2002). In order to further substantiate the impact of the Iberian Pyrite Belt on the high metal levels measured in the interstitial waters of Doñana, we calculated the Metal:Al ratios for the interstitial waters collected in this study and compared them to the ratios reported for the Tinto and Odiel Rivers (Elbaz-Poulichet et al, 1999).…”

The composition of interstitial waters in Spain's Doñana National Park was assessed 4 years after a major pyrite slurry spill occurred from the Aznalcollar Mine. Metal and nutrient concentrations in pore waters from two of the most important watercourses traversing Doñana Park were measured: Guadiamar River (affected by the accident) and Partido Stream (unimpacted by the accident). Concentrations of dissolved constituents in interstitial waters varied according to land use in the two watersheds and to the effects of the mine spill. Levels of dissolved Co, Cu, Mo, Ti, and Zn were higher in pore waters from the Guadiamar River than in the Partido Stream, suggesting that concentrations of trace elements are still influenced by the spill. In contrast, concentrations of dissolved nutrients (NH4+, NO2-, NO3-, PO4(-3)) and some trace metals used in fertilizers (e.g. Al and Cr) were higher in the Partido Stream. Levels of dissolved As, Cs, DOC, Ge, Hg, Rb and V in the interstitial waters were equal in both watercourses. Metal concentrations in interstitial waters of the Guadiamar River floodplain were between 0.3 (As) and 16,000 (Zn) times lower than those previously reported in the river and groundwater a few weeks after the mine spill. Although metals in pore water appear to have reached levels characteristic of the area before the accident, concentrations are 60-150 times higher than those in pore waters from other regions. Metal:Al ratios in Doñana's pore waters suggest a transport of contaminants from the Iberian Pyrite Belt into Doñana Park.

“…The VIP has been successfully applied to in situ monitoring, at time scale of 1 hour, of the concentration of the dynamic fraction of trace metals (i.e., Cu(II), Pb(II), Cd(II), Zn(II), Mn(II)) and their temporal and/or spatial evolution in freshwater [28,30,33], groundwater [44], fjord waters [26], estuarine and coastal marine waters [26,27] and , in some cases for autonomous in situ measurements up to one week. The MPCP has been successfully applied for attended and remote in situ monitoring and profiling in various estuaries and coastal seawaters [31] and more recently in freshwater (Sec.…”

This article gives a review of the analytical and environmental criteria which must be considered and the relevant specific developments needed for direct, reliable voltammetric measurements of trace metal speciation in environmental systems. In particular, this article will focus on the tools which enable remote, long-term in situ measurements. The development of such tools is a challenging task. The strategies that can be used to achieve this goal are described for the development of innovative and versatile gel-integrated voltammetric microsensors, micro-/ mini-integrated analytical systems, and submersible probes. The advantages of these new tools with respect to selectivity, sensitivity, reliability, spatial and temporal resolution of data, and thus efficient environmental monitoring of the biogeochemical cycle of trace metals are demonstrated by providing examples of measurements made in various aquatic samples in laboratory (water, soils, solid -liquid interface) and in situ in fresh and seawaters.

“…Techniques inherited from oceanography allow hydrochemical logging with multiple electrode sets for pH, dissolved oxygen, conductivity, redox, temperature and dissolved compounds, and have been applied to different settings. In particular, they allow taking advantage of chemical stratification in different fields, such as the exploration for concealed deposits (Pauwels et al, 2002), identification of levels to be sampled in groundwater contaminated with metals and organochlorine compounds (Roy and Fouillac, 2004), or the characterization of groundwater bodies as required by the European Water Framework Directive (Négrel et al, 2008).…”
