Abstract

The concentrations of nickel, copper, iron, chromium, lead, cadmium, manganese and zinc have been studied in a small river in South Wales. The river drains the contaminated industrial wasteland of the Lower Swansea Valley which is currently undergoing redevelopment and landscaping activity. The high trace metal levels found in the river waters result from weathering and erosion of this waste material, as well as from two industrial point sources of nickel, and iron and chromium. Hydrological factors found to be of importance in determining current spatial and temporal patterns of contamination included: (1) the river's available dilution at any one time, (2) antecedent river flow conditions, (3) river water pH and (4) the prevailing runoff processes in operation at any one time. The metals are present mostly in their dissolved state (i.e. > 70%), with the exception of iron and chromium which are present mostly as particulates (i.e > 80%).

Accumulation and histological location of heavy metals in Phragmites australis grown in acid mine drainage contaminated soil with or without citric acid
2014, Environmental and Experimental Botany
Citation Excerpt :
Once it enters local water, AMD can acidify and decrease pH of water to as low as 2.0–4.5, which is harmful to most of aquatic life (Batty and Younger, 2003). As such, it is not surprising that regions of the United States and other countries have been adversely affected by AMD (Batty and Younger, 2003; Bird, 1987; Herlihy et al., 1990). For instance, the results of National Stream Survey conducted by the U.S. Environmental Protection Agency in 1998 showed that 4590 ± 1670 km of streams were acidic because of AMD and another 5780 ± 2090 km of streams were also impacted by AMD without being acidic in the eastern United States (Herlihy et al., 1990).
Acid mine drainage (AMD) is a serious environmental issue. This study investigated the heavy metal accumulation and histological alterations caused by heavy metals and citric acid (CA) in reeds grown in AMD contaminated field or spiked soil. The results indicated that the roots and rhizomes accumulated more metals from soil containing higher level of metals. Most of Fe was stored in the exodermis of roots grown in sites that contained less Fe, while Fe had extended to the endodermis of roots grown in sites with higher levels of Fe. Al was found in the exodermis and endodermis of roots collected from sites with lower Al concentrations, but the stele of roots grown in sites with higher level of Al also contained Al. Low level of CA caused Fe enter the pith of roots, while higher level of CA resulted Fe being in the entire stele of roots. CA also altered the Al storage location in roots by enhancing Al entering stele. For rhizomes, the epidermis, cortex and central cylinder were the main sites to store Fe and Al. CA increased the storage of Fe and Al in the tissues around vascular bundles of rhizomes. The higher concentrations of Fe or Al in roots or rhizomes, the stronger intensity of the staining was observed. The quantitative data of heavy metal content also supported the hypothesis that CA can increase the bioavailability of heavy metals in soils and thus enhance the accumulation and translocation of Fe and Al. In general, the higher level of CA added into the soil, the more metals uptake by reeds.
Bioremediation of acid mine drainage: An introduction to the Wheal Jane wetlands project
2005, Science of the Total Environment
Acid mine drainage (AMD) is a widespread environmental problem associated with both working and abandoned mining operations. As part of an overall strategy to determine a long-term treatment option for AMD, a pilot passive treatment plant was constructed in 1994 at Wheal Jane Mine in Cornwall, UK. The plant consists of three separate systems; each containing aerobic reed beds, anaerobic cell and rock filters, and represents the largest European experimental facility of its kind. The systems only differ by the type of pre-treatment utilised to increase the pH of the influent minewater (pH<4): lime-dosed (LD), anoxic limestone drain (ALD) and lime free (LF), which receives no form of pre-treatment. The Wheal Jane pilot plant offered a unique facility and a major research project was established to evaluate the pilot plant and study in detail the biological mechanisms and the geochemical and physical processes that control passive treatment systems. The project has led to data, knowledge, models and design criteria for the future design, planning and sustainable management of passive treatment systems. A multidisciplinary team of scientists and managers from the U.K. universities, the Environment Agency and the Mining Industry has been put together to obtain the maximum advantage from the excellent facilities facility at Wheal Jane.
Heavy metals in the waters of the Nant-y-Fendrod: Change in pollution levels and dynamics associated with the redevelopment of the Lower Swansea Valley, South Wales, UK
2001, Science of the Total Environment
Approximately 240 years (c. 1720–1960) as a world centre for the metal smelting industry left the Lower Swansea Valley as a derelict urban landscape with severe Cu, Zn, Pb, Cd and Ni and metal contamination. Using analysis of archival water quality and discharge records, this paper assesses changes in river pollution over the period 1966–1999 for the Nant-y-Fendrod stream. The marked reduction in metal pollution levels over the period can be linked to the cessation of remaining metal smelting activity and to the rehabilitation and redevelopment measures and their timing. Pollution, both in the past and currently, is shown to be episodic rather than continuous and relationships of high pollution levels to antecedent weather, season, discharge and hydrograph position are explored. Some of the highest levels were recorded during redevelopment itself. Prospects for metal pollution episodes in the Nant-y-Fendrod with further redevelopment in the Lower Swansea Valley in the future are briefly discussed.
Geochemistry of suspended particles in a mine-affected mountain stream
2001, Applied Geochemistry
The particles in a mine drainage and the creek into which it drains were examined using microbeam and filtration methods. The composition of the particles in the drainage and creek were distinctly different, though both carried a chemical signal from the mine. High concentrations of particles made up of Fe and S were seen in the drainage, especially during low flow. The molar Fe:S ratio of these suspended particles was 3.5:1. The influx of the mine drainage into the creek increased the relative number of aggregates and particles with associated Fe. However, few discrete Fe–S particles were seen in the creek, where solid-phase Fe and S were consistently associated with aluminosilicate minerals. Instream precipitation is predicted and appears to be an important additional source of Fe and Al oxyhydroxides to the particles. Some of the Fe and Al associated with particles in the creek was acid-soluble, but most of the acid-soluble Zn, Mn, Cu, Ca, Mg and Si were transported in the <0.45 μm fraction at a site downstream of the mine drainage. One third of the suspended particles had associated P. These suspended particles take part in the complex geochemistry of this system, and represent an important pool as a potential sink and source of metals and other elements.
Changes in chemical and <sup>87</sup>Sr/<sup>86</sup>Sr signature distribution patterns of suspended matter and bed sediments in the upper Loire river basin (France)
1999, Chemical Geology
The mineralogy of the suspended particulate matter (SPM) transported by the upper Loire river consists mainly of quartz and K-feldspar during periods of high river flow, with an increase in calcite concentration during periods of low flow. Concurrently, large fluctuations are observed in the levels of CaO and Fe₂O₃, the main oxides present in the SPM along with SiO₂. The analysed trace elements also fluctuate significantly. The bed sediments (BS) have a similar oxide content to the SPM, but lower Zn and Pb levels and higher Zr levels. Fluctuations in the chemical-element concentrations with river discharge are related to fluctuation in the mineral assemblages present in the SPM. Thus K, Ti and Rb levels increase with increasing in K-feldspar abundance during high flow, and Ca and Sr levels decrease with increasing discharge due to a decrease in calcite abundance. These mineralogical and chemical variations relate to different sources of sediments under different flow conditions—sources that can be distinguished by Sr isotopic study. The Sr isotopic composition fluctuates according to the rate of river discharge; i.e., the $^{87} Sr$ / $^{86} Sr$ ratio increases with increasing discharge and reaches a maximum with peak flow, and vice versa. The $^{87} Sr$ / $^{86} Sr$ ratio also increases with the combined increase in K-feldspar abundance and decrease in calcite abundance. These similarities suggest the existence of at least two particulate-matter reservoirs, one with detrital silicates and the other with carbonates. Finally, the relationship between the $^{87} Sr$ / $^{86} Sr$ ratios in the suspended and dissolved loads suggests the coexistence of authigenic calcite in the carbonate reservoir. The SPM flow is related to a specific mechanical erosion rate over the whole Loire watershed ranging from 9 to 23 t km⁻² yr⁻¹. During the survey at Orleans, the SPM flow of the Loire river was 37·10⁴ t yr⁻¹, providing an estimate of the specific erosion rate of around 9.8 t km⁻² yr⁻¹. From the shift in the SPM flux between the sampling point and the mouth of the Loire river and the divergence in the mean annual discharge, a calculation was made of the input of solid matter by the tributaries and by supplementary erosion processes along the river.
Topography, weather and human activity effects on the behavior of metallic elements in a tropical catchment
1994, Chemical Geology
The geochemical behavior of metals in 11 rivers of the Lake Valencia drainage system, north-central Venezuela, was investigated by repeated sampling. Pb, Zn, Ni, Cu and Cr discharges from domestic and industrial activities have resulted in concentration increases of 2–16× above background levels, depending on the metal, as well as an increase of 13–27% of the labile fraction (% LF). No apparent effect on the metals' grain-size distribution was observed.
Evidence suggests that chemical reactions, coupled with transport of sediments from the mountainous areas to lowland areas, produce: (1) an increase in metal concentration and % LF, which are concomitant with the pollution effect; and (2) a metals' grain-size redistribution toward fine fractions. Analysis of major elements, i.e. Na, K, Mg, Ca, Al and Fe, provides a suitable approach to discriminate the two effects mentioned above. The wet-dry season variability in metal concentration appeared to be controlled mainly by the input of flushed material from soil. This process can explain the large areal variability of concentrations compared with sampling and analytical variability. A physical dilution of Zn with less contaminated, flushed soil material was also observed.
