Two Phases

The Tri-State Mining District (TSMD) of Kansas, Missouri, and Oklahoma was a world class zinc (Zn) and lead (Pb) producer. Mining ceased in the 1950s, leaving behind a large amount of mine wastes. Although much of the affected areas have been remediated, stream sediments may still contain toxic levels of these metals. The mobility of the metals was determined for sediment samples from Turkey Creek, Missouri. The median values of the metal content were 2700 mg/kg Zn, 161 mg/kg Pb, and 10.8 mg/kg Cd. These concentrations marginally surpass the sediment quality guidelines that differentiate between toxic and nontoxic conditions. Mobility was determined by sequential extraction of two phases—bioavailable and Fe-oxides. The fraction of the metal available to biota was 7.7% for Zn, 5.0% for Cd, and 0.4% for Pb, whereas the Fe-oxide fraction retained 25% of Zn, 21% of Pb, and 35% Cd. These values roughly agree with the values reported for other areas of the TSMD. Fractionation provides an estimate of the amount of metal available at the present conditions and gives the amount of metal available should the pH and/or Eh vary. The methodology puts an emphasis on ecosystem health and can be applied to other areas where Zn–Pb concentrations in soils and sediments are a concern.

<p>The Mediterranean area hosts three important mercury mining districts, which are presently abandoned and partially reclaimed: Almadén (Spain), Monte Amiata-Abbadia San Salvatore (Italy) and Idrija (Slovenia). The Galleria Italia (Italy) is the only mining drainage of the former mining area from Abbadia San Salvatore, which feeds the 2.5 km long Fosso della Chiusa. The Galleria Italia waters are circumneutral (pH ≈ 6) and characterized by Ca(Mg)-SO<sub>4</sub> composition; TDS around 1000 mg/L; high concentrations of Fe, Mn and Al (18714.5, 493.3, 486.6 μg/L, respectively) and dissolved CO<sub>2</sub>. The high content of these elements is also present in the stream sediments. In the mining district area of Abbadia San Salvatore, the Galleria Italia-Fosso della Chiusa system is connected to a major riverine network: i.e. the Pagliola, Paglia and Tiber rivers. This work is aimed to (i) characterize the interaction of Hg and As between the water and sediment compartments in the Fosso della Chiusa by including the suspended particulate; (ii) estimate the total Hg and As mass load released by Galleria Italia and iii) evaluate the total load discharged in the riverine network from the circumneutral mine drainage using the Igeo index. In 2020, during four sampling sessions, waters, sediments and suspended particulate were collected all along the Fosso della Chiusa creek. Each sampling station was located maintaining a relatively equidistance from the source to the confluence with the Pagliola river. Specific aliquots at 13 sites were collected to geochemically characterize the creek waters. Also, stream sediments were collected for determining the mineral composition and As, Hg, Sb while at the source and the mouth  2 L of waters were filtered at  <0.45 μm to measure the suspended material and the concentration of three chalcophile elements. A general decrease of the As content was observed along the creek in both waters and sediments, i.e. from 336 to 2 mg/kg and from 12 to 0.3 μg/L, respectively whereas no a clear trend was recognized for Hg, where the higher contents being up to 105 mg/kg and 2.8 μg/L, respectively. It is to mention that the reddish-whitish colour of the waters and sediments (due to the presence of oxy-hydroxide of Fe and, subordinately, Al and Mn) decreasing down to about 1 km from the source, suggesting, as supported by the analytical data, that the presence of the toxic elements in both the solid and aqueous phase. This implies that the environmental impact by the Galleria Italia waters and related sediments is limited spatially at least for As, as also evidenced by the Igeo index applied to sediments for As and Hg, the former showing a general decrease from Class 6 ( “extremely contaminated’’) to 1 (‘’non to moderately contaminated’’). Differently, Hg in each sampling site belongs to Class 6. Nevertheless, the Igeo ranking suggests that As tends to be preferentially partitioned in the liquid phase whilst Hg is mainly enriched in the solid fraction. This contrasting behaviour of As and Hg is also analytically observed when the suspended particulate is considered.</p><p> </p>
