“…erant plants of H. lanatus have restricted uptake of arsenate compared with non-tolerant plants, yet the tolerant plants are capable of accumulating arsenic to high concentrations over longer time periods. Benson et al (1981) and Porter & Peterson (1975) also report high levels of As accumulation in a number of arsenate tolerant Agrostis species growing on arsenate contaminated mine soils. These plants can accumulate up to 1 % As on a plant dry weight basis.…”

“…Arsenate-tolerant angiosperms have been collected from arsenate-contaminated soils (Porter & Peterson, 1975, 1977Rocovich & West, 1975;Pollard, 1980;Benson, Porter & Peterson, 1981 ;Macnair & Cumbes, 1987;Watkins & Macnair, 1990). Meharg & Macnair (1990) studied short-term uptake of arsenate in excised roots of arsenate-tolerant and non-tolerant genotypes of Holcus lanatus L. The rate of arsenate uptake in non-tolerant roots was much greater than in tolerant roots.…”

Uptake, accumulation and translocation of arsenate in arsenate‐tolerant and non‐tolerant Holcus lanatus L.

SUMMARYUptake, translocation and accumulation of arsenate was determined in arsenate-tolerant and non-tolerant genotypes of Holcus lanatus L. Over a 6 h period of growth in 0-05 mol m"^ arsenate, non-tolerant genotypes accumulated arsenate to a much greater extent than tolerant plants. Tolerant plants transported a much greater proportion of As to their shoots compared with non-tolerant plants. Phosphate at a concentration of either 0-OS or 0-5 mol m"" decreased arsenate uptake in both tolerant and non-tolerant genotypes. When arsenate uptake was determined over 3 d at the same arsenate concentration, non-tolerant plants grown in the presence of 0 and 0-05 mol m"' phosphate died, while those growing in 0-5 mol m"' phosphate survived and continued to take up arsenate. At all three phosphate levels tolerant plants survived. Over the 3 d period transport of arsenate to the shoots decreased. With increasing phosphate levels in solution transport of arsenate to the shoots increased in tolerant plants. The results from these experiments are discussed in terms of strategies for metal tolerance in this species.

“…Much higher As concentrations were found in several plants from 5. 53 (3.50-8) mine wastes in the UK (6,640 mg/kg; Porter and Peterson 1975), north-eastern Portugal (60-300 mg/kg; de Koe 1994), and a geothermal area in New Zealand (1,766 mg/kg; Robinson et al 2006). Given the criterion of [1,000 mg/kg foliar As (Ma et al 2001), such plants could be considered as As hyperaccumulators.…”

Plant and soil samples were collected from one uncontaminated and four contaminated sites (in the Dashkasan mining area western Iran). Total and water-soluble arsenic in the soil ranged from 7 to 795 and from 0.007 to 2.32 mg/kg, respectively. The highest arsenic concentration in soil was found at the ore dressing area (up to 1,180 mg/kg) and lowest at an uncontaminated area (up to 11 mg/kg). A total of 49 plant species belonging to 15 families were collected from four sampling sites. A significant positive correlation was detected between the concentrations of arsenic in plant dry matter and those in soils. The highest arsenic concentrations were found in Hyoscyamus kurdicus Bornm. (up to 205 mg/kg) and Helichrysum oligocephalum DC. (up to 162 mg/kg). These two accumulator species could have potential for soil clean-up by phytoextraction. The data have been compared with those for the Zarshuran mining area (north-western Iran) obtained in a former study.

“…2). 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).…”

Gašová, K., Kuklová, K., Kukla, J., 2017. Contents of nutrients and arsenic in litterfall and surface humus in mature nudal beech stands subjected to different emission-immission loads. Folia Oecologica,.The aim of the paper was to compare the litterfall and surface humus (Oo) quality in nudal beech stands with different emission-immission load from the Al smelter Žiar nad Hronom. The study was carried out in the Kremnické vrchy Mts (control stand, 18 km from the emission source) and the Štiavnické vrchy Mts (stressed stand, 1.5 km from the emission source), both in Central Slovakia. The contents of arsenic and nutrients (Ca t , Mg t , K t , Na t ), with exception of calcium in the beech litterfall from the stressed stand were markedly higher (by 4.3%, 23.9%, 2.1% and 87.9%, respectively) compared to the samples taken from the control plot. On the contrary, the surface humus samples (with the exception of Na in the necrotic Oon subhorizon) from control plot were richer in nutrients. However, significant differences (p < 0.01) between the plots were observed for Ca content in the litterfall as well as in the surface humus. The concentrations of As in Oo samples from the stressed stand mainly increased with the organic horizon depth (mg kg -1 ): necrotic Oon 1.10 < fermentation Oof 3.1 < humification Ooh 55.6. The results showed, that As amounts detected in subhorizon Ooh and in beech litterfall from the stressed stand were higher than the limit values, thus indicating that the environment of the Žiar territory is exposed to persistent negative impacts of industrial activities.
