“…Although the quantity of arsenic present in sunflower shoot is not comparable to that obtained in other studies by using hyper accumulating plants (Wei et al 2010), the results evidenced that the arsenic up taken by sunflower exceeded the limit reported for food crops (1 mg kg -1 ) (Bhattacharya et al 2010). This confirms the estimation made by Warren et al (2003) which states that crops grown in soil with more than 200 mg kg -1 arsenic cause food poisoning. Moreover, consumption of rice and vegetables grown in arsenic contaminated agricultural soils is the second most common route of arsenic poisoning in Bangladesh (Chowdhury 2004).…”

“…Although sunflower (Helianthus annuus L.) has been proposed for phyto-extraction purposes because it uptakes relatively high concentrations of metals and can have high biomass yield (Marchiol et al 2007), literature is scarce about its ability to translocate arsenic. Arsenic uptaken by food crops should not exceed the limit of 1 mg kg -1 (Bhattacharya et al 2010) and health hazards for food poisoning might be present when crops grow in soils with arsenic content higher than 200 mg kg -1 (Warren et al 2003).…”

In the present study, six arsenic-resistant strains previously isolated were tested for their plant growth promoting characteristics and heavy metal resistance, in order to choose one model strain as an inoculum for sunflower plants in pot experiments. The aim was to investigate the effect of arsenic-resistant strain on sunflower growth and on arsenic uptake from arsenic contaminated soil. Based on plant growth promoting characteristics and heavy metal resistance, Alcaligenes sp. strain Dhal-L was chosen as an inoculum. Beside the ability to reduce arsenate to arsenite via an Ars operon, the strain exhibited 1-amino-cyclopropane-1-carboxylic acid deaminase activity and it was also able to produce siderophore and indole acetic acid. Pot experiments were conducted with an agricultural soil contaminated with arsenic (214 mg kg -1 ). A real time PCR method was set up based on the quantification of ACR3(2) type of arsenite efflux pump carried by Alcaligenes sp. strain Dhal-L, in order to monitor presence and colonisation of the strain in the bulk and rhizospheric soil. As a result of strain inoculation, arsenic uptake by plants was increased by 53 %, whereas ACR3(2) gene copy number in rhizospheric soil was 100 times higher in inoculated than in control pots, indicating the colonisation of strain. The results indicated that the presence of arsenate reducing strains in the rhizosphere of sunflower influences arsenic mobilization and promotes arsenic uptake by plant.

“…The lowest BCFplants value was for As, approximately two orders of magnitude less than for the other elements, indicating very low transfer of As from soil to plants. This agrees with literature where soil-plant transfer coefficients b0.01 are described for this element (Adriano, 2001;Warren et al, 2003). Transference of trace metals from soils to plants decreases with soil concentration increase (McLaughlin, 2001), even showing a plateau when soil concentration exceeds a certain limit (Hamon et al, 1999).…”

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.

“…The concentration of arsenic in cereals, vegetables and fruits is directly related to the level of arsenic in the soil (Kazia et al, 2009). Severe arsenic contamination of soils may cause arsenic toxicity in plants, animals and human (Warren et al, 2003). Remediation of arsenic contaminated soils has thus become a major environmental issue.…”

Arsenic concentrations of surface waters, soils and plants were surveyed in three contaminated villages of Bijar County. Total arsenic in water samples (4.5 to 280 µg/L) was correlated with electrical conductivity, total dissolved solid, total hardness, alkalinity, chloride, sulphate, bicarbonate, calcium and sodium (p<0.001). Total arsenic in the soils ranged from 105.4 to 1500 mg/kg. Some of the soil factors play an important role in soil arsenic content and its bioavailability for organisms. In general, the arsenic concentrations in plants were low, especially in the most common wild species. Among 13 plant species, the highest mean arsenic concentration was found in leaves of Mentha Longifolia (79.4 mg/kg). Arsenic levels in soils and plants were positively correlated, while the ability of the plants to accumulate the element, expressed by their biological accumulation coefficients and arsenic transfer factors, was independent of the soil arsenic concentration. Relationships between the arsenic concentrations in plants, soils and surface water and the environmental aspects of these relationships have been discussed in comparison with literature data. The accumulation of arsenic in environmental samples (soil, sediment, water, plant, etc.) poses a potential risk to human health due to the transfer of this element in aquatic media, their uptake by plants and subsequent introduction into the food chain.
