“…In this section, the rivers run through quaternary fluvial sandy and loamy terraces. Compared with the previous sections, soils from this section show higher pH and conductivity, maintain high concentrations of S, Fe, As, and Pb, and present the highest concentrations of Cu and Zn [2,4,5].…”

“…These wastes are the potential sources of the metals (Fe, Cu, Zn, As, and Pb), that are then leached in the predominant extreme acid conditions of this territory. Recent studies reported high concentrations of these elements in vegetated soils and sediments from the entire river basin [4].…”

“…While the mineralogy, composition, and physico-chemical properties of the water, sediment, alluvium, and soils along the Río Tinto have been the object of several studies [1,3,4,[9][10][11][12], reports on metal concentration in Río Tinto plants are scarce. Knowledge of plant metal concentration is of special interest to issues ranging from human and animal diet or bioindication of metal polluted water and soils.…”

Río Tinto (Huelva, Spain) is located in one of the most important mining regions in the world. Its soils are characterized by their extreme acidity and elevated concentrations of heavy metals. Due to these characteristics, the Tinto ecosystem is considered unique and an ideal location to study biological adaptations to this type of habitat. Plant species that present these adaptations might be useful to mining and other metal pollution restoration programs. This study reports the results for the screening of Ca, Mg, Na, Mn, Fe, Ni, Cu, Zn, As, and Pb in aerial tissues of 97 plant species from the Tinto basin flora. In addition, plant-soil relationships were analyzed using the biological absorption coefficient (BAC) to detect the main plant adaptations in the Tinto flora. The species selected are representative of the biomass of the main dominant edaphophile and climatophile vegetation communities of the three river sections, forest, and subseral stages. Plant and soil elemental analyses were performed using inductively coupled plasma-mass spectrometry technique (ICP-MS). The results indicate that in general, Tinto flora shows a pattern of accumulation of the analyzed elements in aerial tissues which agrees with the nutritional requirements of vascular plants (macronutrients > micronutrients > indifferent or toxic elements). Among macronutrients, Ca seems to be an essential element in this habitat. This element accumulates in the aerial plant tissues. Basically, the Río Tinto flora is made of Fe, Cu, Zn, Ni, As, and Pb excluders, although some analyzed species of Erica, Quercus, Lavandula, Cistus, Genista, and Cytisus genera can be considered Mn accumulators. The results of this study make up a body of fundamental knowledge of the strategies used by plants to thrive in habitats with high concentrations of toxic heavy metals. This information is vital when it comes to planning a restoration program. Plants must be selected and used according to the requirements, always respecting the characteristics of the territory and facilitating the development of suitable vegetation.

“…Concerning mining activities, presently mines are specifically designed with mitigation methods to manage potential environmental impacts; however, in former mines the extracted mineral deposits may remain after mines have been abandoned and usually become a large and uncontrolled source of metal and metalloid contamination. There are many areas impacted by pyritic mine spreading all around Spain (Álvarez et al, 2003;Clemente et al, 2006;Rufo et al, 2007), which after becoming derelict sites now require environmental rectifications. In the pyrite deposits, natural weathering interaction may release elements such as As, Zn, Pb, Cu, Mn, Cd, Mo, Cr, and Ni which may contaminate water, soil and plant ecosystems at unacceptable levels (Quevauviller et al, 1989;Santos Oliveira et al, 2002).…”

El acceso a la versión del editor puede requerir la suscripción del recurso Access to the published version may require subscription This paper describes a new methodology for assessing site-specific environmental impact of contaminants. The proposed method integrates traditional risk assessment approaches with real and variable environmental characteristics at a local scale. Environmental impact on selected receptors was classified for each environmental compartment into 5 categories derived from the whole (chronic and acute) risk assessment using 8 risk levels. Risk levels were established according to three hazard quotients (HQs) which represented the ratio of exposure to acute and chronic toxicity values. This tool allowed integrating in only one impact category all the elements involved in the standard risk assessment. The methodology was applied to an abandoned metal mine in Spain, where high levels of As, Cd, Zn and Cu were detected. Risk affecting potential receptors such as aquatic and soil organisms and terrestrial vertebrates were assessed. Whole results showed that impact to the ecosystem is likely high and further investigation or remedial actions are necessary. Some proposals to refine the risk assessment for a more realistic diagnostic are included.Published by Elsevier B.V.
