“…Comparing the As concentration in the selected plants of this study with those sampled at mining sites with higher soil As concentrations (de Koe 1994;Bech et al, 1997;Madejo´n et al, 2002), the bioconcentration is found to be much lower maximum values (from less than one-half to less than one-tenth). Since As concentrations in the soils of study area were also lower, this is consistent with the idea that the soil to plant As transfer coefficient are more or less independent of the soil As concentrations.…”

“…Porter and Peterson (1975) report some plant species growing on As mine wastes (south-west England, UK) containing average arsenic levels ranging from 350 to 2,040 mg kg -1 . Another example is the mean concentrations of As in leaves of plants growing near a copper mine (northern Peru) ranging from 111 to 1,651 mg kg -1 (Bech et al, 1997). Temple et al (1977) found average As contents of 5.80 mg kg -1 in grass samples and 7.40 mg kg -1 in tree and shrub foliage 700 m away from a secondary lead smelter; with the samples collected at a control site containing < 1 mg kg -1 .…”

“…Considering that the samples were collect at the same polluted sites, these variations may reflect differences in arsenic bioavailability between sampling location. According to Bech et al, 19 in soils with high total arsenic concentration, the available arsenic fraction seems to be strongly influenced by soil texture and pH. Moreover, differences in mineral content, especially Fe and Mn content in sampling locations may also interfere in arsenic bioavailability.…”
