“…One method of obtaining more realistic risk estimation is to quantify the fraction of metals in soils that is really bioavailable. However, at present a method which allows correlating toxicity to soil organisms and bioavailable fraction in soil is not generally admitted (Berthelot et al, 2008;McLaughlin et al, 2000). Moreover, the sensitivity of metal bioavailability to temporal changes in soil conditions complicates the use of models based on the free ion activity or extractant solutions.…”

“…Releases may cause direct adverse effects on terrestrial and aquatic organisms. Moreover some trace elements can be incorporated in plants and/or animals leading under certain circumstances to secondary poisoning in vertebrates due to the consumption of contaminated food (Anawar et al, 2006;Chen and Liu, 2006;McLaughlin et al, 2000). Therefore, the management of abandoned derelict mines is a major concern.…”

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.

“…Therefore, Cd should not contribute to the toxicity of the mixture, except for the indicated exception (McLaughlin et al, 2000). Taking into account the high toxic index determined for soils near the mine, especially for their As content (Table 8), a higher toxicity in S2 to plants and in S3 to earthworms is expected.…”

“…Extractions with neutral salt solutions based on desorption or ionic exchange processes result in low concentrations of elements. However, different studies show that this fraction is a good predictor for element uptake by plants and earthworms, which absorb toxicants predominantly via a soil solution/dermal route, especially in the case of metals [McLaughlin et al, 2000;Berthelot et al, 2008). …”

“…Under these assumptions, the risk may be overestimated and may result in unnecessary remediation (Alexander, 2000;Ollson et al, 2009). A risk assessment based on geochemical analyses is highly simplified and does not take into account factors such as the bioavailability of a contaminant or the simultaneous presence of different contaminants, which can affect toxicity and exposure estimates (McLaughlin et al, 2000;De Zwart and Posthuma, 2005;O'Halloran, 2006). These facts are of the utmost importance for hazardous elements.…”

El acceso a la versión del editor puede requerir la suscripción del recurso Access to the published version may require subscription AbstractThis research reports the risk assessment of an abandoned pyrite mine using direct toxicity assays of soil and groundwater samples taken at the site. The toxicity of As and heavy metals from mining soils to soil and aquatic organisms was studied using the Multispecies Soil System (MS-3) in soil columns. Ecotoxicological assessment was performed with soil samples diluted with a control soil at concentrations of 12.5, 25, 50 and 100% test soil/ soil (w/w). In this way, changes in the mobility and bioavailability of soil contaminants due to changes in geochemical soil properties via soil dilution were studied. The toxicity of water samples was tested on algae and Daphnia magna. The assessment of the mining area indicated that the current presence of As and heavy metals at the site may cause injuries to soil and aquatic organisms in the entire research area. Moreover, this investigation demonstrated that changes in geochemical conditions can increase the availability of arsenic and, consequently, the environmental risk of these soils. A good correlation was not found between toxicity parameters and the concentrations of soil contaminants based on total and extracted element concentrations. This finding reinforces the usefulness of direct toxicity assays for evaluating environmental risk.
