“…For Swansea and Northampton (n = 15), replicate bioaccessibility values for BGS 102 were within the consensus values, with 'stomach' phase values of 17.6 ± 5.9 mg kg -1 . The value obtained for Pb in page 10 of 35 the NIST 2710 reference material for the Glasgow samples (n = 4) was 3691 ± 416 mg kg -1 for the 'stomach', which was in good agreement with consensus value of 3785 ± 469 mg kg -1 for this material (Farmer et al, 2011).…”

“…The samples from London were selected primarily to cover the wide range of total Pb concentrations, whilst those from Swansea and Northampton were selected to represent a range of Pb and As concentrations; the results of the As bioaccessibility in UK urban soils will be published in a separate paper. Data for regression modelling in the Glasgow area is for the G-BASE samples reported in Broadway et al (2010) and page 7 of 35 Farmer et al, (2011) which were originally selected to provide a range of total Cr, Pb or As concentrations. Summary statistics for all the samples from the four urban areas are reported in Flight and Scheib (2011).…”

“…A significant proportion of the urban landscape in Great Britain has elevated topsoil concentrations of lead (Pb; Rawlins et al, 2005;Thums et al, 2008;Broadway et al, 2010;Farmer et al, 2011;Flight and Scheib, 2011). In a study of the background concentrations of potentially harmful elements (PHEs) in soils in England, Cave et al (2012) and Ander et al (2012) used a classification based on the ratio of built to open space to show that 4% of the land area could be classified as Urban and that systematically surveyed soil samples in this category (n=7529) had median and 95 th percentile lead concentrations of 170 mg kg -1 and 790 mg kg -1 respectively.…”

“…A number of workers have successfully carried out multiple linear regression (MLR) modelling of the bioaccessible PHE content of soils, specifically arsenic (As), using their physicochemical properties, such as the elemental composition of the soil and soil pH as the predictor variables (Yang et al, 2002;Klinck et al, 2005;Tang et al, 2007). Pb bioaccessibility studies have generally focussed on the relationships between total and bioaccessible Pb concentrations (Farmer et al, 2011;Cave et al, 2011) sometimes with due consideration given to the different sources of Pb contamination (Smith et al 2011). …”

Predictive linear regression (LR) modelling between bioaccessible Pb and a range of total elemental compositions and soil properties was executed for the Glasgow, London, Northampton and Swansea urban areas in order to assess the potential for developing a national urban bioaccessible Pb dataset for the UK. LR indicates that total Pb is the only highly significant independent variable for estimating the bioaccessibility of Pb.Bootstrap resampling shows that the relationship between total Pb and bioaccessible Pb is broadly the same in the four urban areas. The median bioaccessible fraction ranges from 38% in Northampton to 68% in London and Swansea. Results of this study can be used as part of a lines of evidence approach to localised risk assessment but should not be used to replace bioaccessibility testing at individual sites where local conditions may vary considerably from the broad overview presented in this study. Capsule AbstractTotal Pb is the only significant predictor for bioaccessible Pb in topsoils from four urban areas in the UK.

Investigating the uptake and acquisition of potentially toxic elements in plants and health risks associated with the addition of fresh biowaste amendments to industrially contaminated soil

et al. 2017

View full text Add to dashboard Cite

Soil contamination by potentially toxic elements (PTEs), due to rapid industrialization and urbanization, is a serious environmental concern that has been threatening both the sustainability of various agroecosystems and human health. Efforts to investigate the bioavailability, transfer, and accumulation of PTEs in the soil–plant system and their possible health consequences have almost exclusively focused in the past studies. However, there is limited evidence for increased human exposure to PTEs through dietary intake of food crop grown on contaminated soil influenced by fresh biowaste amendments (FBAs). Here, we show that FBAs addition to soil markedly (p ≤ .01) intensified human exposure to PTEs through impacts on solubility, uptake, and bioaccumulation compared with the control. In general, the risk assessment performed indicated that the hazard index values for FBAs treatments were notably higher than that of control; however, these were shown to be less than the legal limit (<1). In addition, the lifetime risks of developing carcinogenicity from exposure to PTEs were far above the maximum regulatory limits (1.00E‐06), indicating that remarkable (p ≤ .01) amount of PTEs was transferred to food with the addition of FBAs. Conclusively, these results suggest that the use of FBAs to contaminated soil aggravates health risks of PTEs through wheat consumption. Further studies, which incorporate the in vitro gastrointestinal bioaccessibility, should be conducted to heighten our understanding about PTEs exposure and the risks associated with FBAs addition to contaminated soil.
