“…To prevent such influences and other interferences (Chakraborti et al, 1980(Chakraborti et al, , 1984Irgolic, 1992) from affecting the results, the standard addition technique employing aqueous solutions of arsenate was used for the quantification of arsenic in the digests. Calibration curves were linear to 2 ng arsenic (injection volume 20 !J.L) with a slope of 0.17 absorption units per ng As supplied as arsenate.…”

Graphite furnace atomic absorption spectrometry (standard addition method) was used to determine the total arsenic in wild-growing mushrooms after digestion with nitric acid, then with perchloric acid and in associated soils after digestion with mixtures of nitric and hydrofluoric acids in a microwave system. Among 83 species of mushrooms the highest concentrations of arsenic on a dry mass basis were found in Laccaria amethystea (26-125 mg kg-1 ), Laccaria laccata (11-33 mg kg-1 ), Thelephora terrestris (38 mg kg-1 ), Boletus cavipes (11.6 mg kg-1 ) and Ramaria botrytis (10 mg kg-1). Mushroom caps of L.laccata, L. amethystea, and B. cavipes had approximately double the arsenic concentrations found in stems. The arsenic concentrations in caps of L. amethystea and L. laccata were directly proportional to the concentrations in the soils. The concentrations of arsenic in the soils were in the range 6.5-65 mg kg-1. Among the 19 mushroom caps with arsenic concentrations above the method detection limit of 0.2 mg As/kg dry mass, only L. amethystea and L. laccata had arsenic concentration ratios 'cap/soil' higher than 1 {between 1.1 and 1.9). Thelephora terrestris had a ratio of 2.37.

“…For example, Al is stable in the environment without interacting with biological processes, its concentration in the soil varies between 10,000 and 300,000 ppm depending on the pH of the soil, but in acidic soils pH <5, it is transformed into its toxic form Al +3 (Gupta et al, 2013). In the case of As, the concentrations in soil are between 1 and 60 ppm and in water for human consumption, values of 50 µg/L have been reported (Cameron, 1992;Irgolic, 1992). Normal Ba concentrations reported for soil are between 15 and 3,500 ppm, while values of <5 to 15,000 µg/L have been reported in water (ATSDR, 2007).…”

“…The quantification of species is difficult because the concentrations of different forms in the environmental samples are very low relative to the detection limits of the available analytical techniques. There have been many reviews of different arsenic speciation analyses (Bednar et al, 2001;Burguera and Burguera, 1997;Guerin et al, 1999;Irgolic, 1992;Morita and Edmonds, 1992;Simon et al, 2004;Vilano et al, 2000, etc.). Examples of various arsenic species separation methods coupled with different detection techniques are given in Table II.…”

Interests in the determination of different arsenic species in natural waters is caused by the fact that toxic effects of arsenic are connected with its chemical forms and oxidation states. In determinations of water samples inorganic arsenate (As(III), As(V)), methylated metabolities (MMAA, DMAA) and other organic forms such as AsB, AsC, arsenosugars or arsenic containing lipids have the most importance. This article provides information about occurrence of the dominant arsenic forms in various water environments. The main factors controlling arsenic speciation in water are described. The quantification of species is difficult because the concentrations of different forms in water samples are relatively low compared to the detection limits of the available analytical techniques. Several hyphenated methods used in arsenic speciation analysis are described. Specific advantages and disadvantages of methods can define their application for a particular sample analysis. Insufficient selectivity and sensitivity of arsenic speciation methods cause searching for a new or modifications already existing techniques. Some aspects of improvement and modifications of the methods are highlighted.
