The content of selenium in some species of meadow plants

Abstract

The aim of the investigation carried out in 2006-2007 was to assess differences between 5 grass species and 5 species of plants belonging to meadow herbs in their ability to accumulate selenium. According to the results, among the grass species, the samples of Arrhenatherum elatuis L. had the highest average Se content (46 µg Se⋅kg-1 d.m.), and the lowest average Se amount was found in Holcus lanatus L. (24 µg Se⋅kg-1 d.m.). The content of Se in meadow weeds (70 µg Se⋅kg-1 d.m.) was approximately twice as high as in grasses (32 µg Se⋅kg-1 dm.). Among this group of plants, the highest Se accumulation occurred in Equisetum arvense L. (103 µg Se⋅kg-1 dm.) and the lowest-in Taraxacum officinale (59 µg Se⋅kg-1 dm.). Both in grasses and in meadow weeds, the Se content significantly depended on the amount of this element in soils. In the following species: Dactylis glomerata L., Arrhenatherum elatius L., Poa pratensis L. and Taraxacum officinale, the amount of accumulated Se was also conditioned by the soil's abundance in organic and total C.

Effect of the Addition of Selenium and some Competing Anions on Selenium Concentration in Maize Growing in some Soils in Central Iraq

“…The results of Figure 4 show the interaction between selenium and sulfate that it ranged between (20.50-137.44 ) (17.48 -77.61 ) μg gm -1 dry matter of the Al-Herria and khan al-Nass respectively for treatments (Se 1 S 3 ) and ( Se 4 S 1 ) respectively. While the interaction between selenium and phosphate in Figure 5 ranged between( 21.68 -137.05) (14.65 -77.47 ) μg gm -1 dry matter of Al-Herria and khan al-Nass respectively for treatments Se1P3 and Se4P1 respectively This results refers at the highest level of phosphorus dose , the selenium concentration was much lower than in the control treatment , and this reselts agrees with the Sinding of [9].…”

“…[8], Showed that application of phosphorus had a negative effect on the plant uptake of Selenium . According to [4,9] The main rejoin for a lower level of Selenium is that applying phosphorous Couse a increase of yield which Creates a dilution effect. The aim of this study was to evaluate the impact of increased levels of Sulfur and phosphorus on the selenium concentration in shoot of Maize plant.…”

Selenium Concentrations of Selected Medicinal and Aromatic Plants in Turkey

“…The lowest values were in Canada, whereas the highest values were recorded in India for grass (352 µg kg -1 ) and alfalfa (672 µg kg -1 ) [15]. Another recent study conducted in Poland aimed to assess differences in Se accumulation between 5 grass species and 5 herb species belonging to meadows [16]. Arrhenatherum elatuis L. had the highest average Se content (46 μg Se⋅kg -1 d.m.…”

Application of sequential analysis with the BCR method in the estimation of effects of chemical remediation of soil polluted with copper

“…In view of the fact that the BCR method is the only standardised procedure with available reference materials, it provides the possibility of comparing various test results, which is not possible with other procedures presented in the world literature. The optimised BCR method is currently applied in studies on the sequential extraction of copper, lead, zinc, iron, manganese, chromium, nickel and cadmium (Zhang et al, 1998;Davidson and Delevoye, 2001;Sutherland and Tack, 2002;Kaasalainen and Yli-Halla, 2003;Fernández et al, 2003;Renella et al, 2004;Araina et al, 2008;Patorczyk-Pytlik and Gediga, 2009;Zimmerman and Weindorf, 2010;Sienkiewicz-Cholewa et al, 2011).…”
