“…As expected, the lowest Pb and As accumulation was measured in animals exposed to soil A and the highest in animals exposed to soil C. The results are in concordance with the reports of trace metals accumulated in isopods exposed to remediated soils (Udovic et al, 2009), in isopods collected in differently polluted areas (Blanuša et al, 2002; Gàl et al, 2008; Heikens et al, 2001; Hussein et al, 2006), or exposed to food spiked with increasing concentrations of trace metals (Gräff et al, 1997; Odendaal and Reinecke, 2004; Witzel, 1998). The opposite effects of compost addition on Pb and As bioavailability in soil already predicted with the chemical extraction tests were reflected also in P. scaber accumulation.…”

“…A simple in vivo test with isopods as indicator organisms was therefore proposed as a supplement to chemical extractions, providing a more complete and relevant picture of the bioavailability of trace metals in soil to organisms. Terrestrial isopods accumulate metals from their environment in proportion to their concentration in the soil (Hopkin et al, 1993), and therefore they appear very suitable as indicators of the metal bioavailable fraction in polluted soil and leaf litter (Gál et al, 2008; Udovic et al, 2009). …”

A long history of lead arsenate application in orchards has led to significant accumulation of Pb and As in the topsoil. Besides the threat that such soils represent for the environment, reclamation of old orchards for agricultural purposes implies the exposure of humans to Pb and As. In this study we assessed the influence of vegetable compost addition (as a sustainable agricultural practice) to contaminated acidic orchard soil on Pb and As bioavailability, assessed with two selective non-exhaustive chemical extractions and with an in vivo bioaccumulation test with an isopod (P. scaber). The treatment with compost caused a significant increase in soil pH and total carbon content, resulting in a consistent decrease of Pb bioavailability. In contrast, the bioavailability of As increased, indicating that a complementary treatment should be used for reducing the bioavailability of As in old orchard soils. This is the first report on the use of As accumulation in P. scaber as a tool for the assessment of As bioavailability in contaminated orchard soil.

“…The most frequently used approach to provide a relative assessment of metal bioavailable from the environment is a calculation of a bioaccumulation factor (Gál et al, 2008). The average BAF in our study (0.20 ± 0.088) was similar to previously reported BAF values (0.10-0.26) in isopods exposed to 300-3000 g/g Zn in the food for 10 days (Bibič et al, 1997).…”

“…In addition to their toxicity, metals persist in soil for long times and have the capacity to be transferred into the food chain [1,2] thus the assessment of their content in soil and the estimation of their transfer rates to vegetation are of great interest [3]. The soil quality guidelines are usually based on total metal content, although it is generally accepted that total metal content include both bioavailable and non-bioavailable fractions [4].…”

BackgroundThe metals bioavailability in soils is commonly assessed by chemical extractions; however a generally accepted method is not yet established. In this study, the effectiveness of Diffusive Gradients in Thin-films (DGT) technique and single extractions in the assessment of metals bioaccumulation in vegetables, and the influence of soil parameters on phytoavailability were evaluated using multivariate statistics. Soil and plants grown in vegetable gardens from mining-affected rural areas, NW Romania, were collected and analysed.ResultsPseudo-total metal content of Cu, Zn and Cd in soil ranged between 17.3-146 mg kg-1, 141–833 mg kg-1 and 0.15-2.05 mg kg-1, respectively, showing enriched contents of these elements. High degrees of metals extractability in 1M HCl and even in 1M NH4Cl were observed. Despite the relatively high total metal concentrations in soil, those found in vegetables were comparable to values typically reported for agricultural crops, probably due to the low concentrations of metals in soil solution (Csoln) and low effective concentrations (CE), assessed by DGT technique. Among the analysed vegetables, the highest metal concentrations were found in carrots roots. By applying multivariate statistics, it was found that CE, Csoln and extraction in 1M NH4Cl, were better predictors for metals bioavailability than the acid extractions applied in this study. Copper transfer to vegetables was strongly influenced by soil organic carbon (OC) and cation exchange capacity (CEC), while pH had a higher influence on Cd transfer from soil to plants.ConclusionsThe results showed that DGT can be used for general evaluation of the risks associated to soil contamination with Cu, Zn and Cd in field conditions. Although quantitative information on metals transfer from soil to vegetables was not observed.
