“…Median soil pH is 5.4, 6.8 and 6.4 for Glasgow (G), London (L) and Northampton (N), respectively; no pH data is available for the Swansea (S) soil samples. The median bioaccessible fraction ranges from 38% in Northampton to 68% in Swansea and London, similar to average bioaccessibility of 49% recorded in urban park soils in Xiamen (Luo et al, 2012a), 59% in Hong Kong urban soils (Luo et al, 2012b), 46-60% in the urban green area soils of Torino (Italy) and Sevilla (Spain) (Madrid et al, 2008) and 48±12% in roadside soils from Torino (Sialelli et al, 2011). Pb bioaccessibility data for peri-urban contaminated soils in Australian and New Zealand (Smith et al, 2011) is mainly for shooting range and mining/smelting impacted soils so it is not comparable with the UK urban bioaccessibility data.…”

“…There are many in vitro studies of the bioaccessibility of trace elements in urban soils (Ljung et al 2007;Madrid et al 2008;Poggio et al 2009;Rasmussen et al 2008;Roussel et al 2010). However, the results are variable and sometimes contradictory, and hence, there is little agreement.…”

“…The varied soil properties in sites can be attributed to, in large extent, the soil parent materials and hydrothermal conditions (Li et al 2014(Li et al , 2015. However, the elevation of heavy metals in Beijing and Baotou were relatively greater than those in other sites, as the two cities might have received more intensive anthropogenic inputs (Madrid et al 2008). In this study, factor analysis had extracted three main factors, including Fac_1, containing mainly pH and soil texture parameters; Fac_2, representing BCR extracted forms of HMs, and Fac_3, containing mainly organic matter (Tables 5 and 6).…”

“…Simple bioaccessibility extraction test (SBET) Madrid et al 2008) was used to assess the bioaccessibility of As, Cr, Cu, Pb, and Zn. Briefly, 50 ml of the 0.4 M glycine extraction solution was added to 0.5 g of sieved (<150 μm fraction), air-dried soil material in a 100 ml polythene centrifuge tube.…”
