“…Tl poisoning is therefore a recognised industrial hazard Shabalina and Spiridonova, 1979), although not wide spread. Some unique applications of Tl are stimulating Tl related research in diverse fields ranging from toxicology (Borgmann, et al, 1998) and biology (Lepp and Logan, 1983) to chemistry (Kocovsky andBaines, 1993, Lin andNriagu, 1999), and environmental monitoring. In these research fields the determination of the Tl(I) and Tl(III) species is important.…”

A new hyphenated method was developed for the speciation of Tl. In this method, Tl(III) was complexed with DTPA to form a Tl(III)-DTPA anionic complex. Tl(I) did not form a complex with DTPA. The two species were separated simultaneously by means of ion chromatography using a Dionex cation exchange guard column, CG12A, and 15 mmol/l nitric acid as eluant. When ICP-OES was used as detector the detection limits for both species were 0.8 mg/l for an inert V-groove nebuliser and 0.1 mg/l for an ultrasonic nebuliser. No spectral interference was observed but high concentrations of metals such as Fe and Al could lead to broadening of the Tl(I) peak. It was demonstrated that the same chromatographic method can be used with ICP-MS detection. Detection limits were then reduced to 25 ng/l for Tl(I) and 70 ng/l for Tl(III).

“…No obstante, se comparan con los datos obtenidos por Borgmann et al (1998) accumulation results obtained in the Guadalquivir estuary experiment for the oyster (C. angulata) specimens were lower than the thallium accumulation results for the amphipod (H. azteca) from the Lake Ontario experiment. Unfortunately, similar field sediment test data from estuarine or marine areas are not available and thus cannot be compared.…”

Thallium in the marine environment: First ecotoxicological assessments in the Guadalquivir estuary and its potential adverse effect on the Doñana European natural reserve after the Aznalcóllar mining spill (SW Spain)

Thallium (Tl) is an extremely toxic but little-studied element in the marine environment and practically no information has been reported on the levels of Tl in marine organisms. After the Aznalcóllar mining spill (April 1998), high levels of metals were put into the environment. This acidcontaminated medium was responsible for the initial pollution effects measured in the Guadiamar River, which is an affluent of the Guadalquivir River and very close to the biggest natural reserve in Europe (Doñana). Four different species were used in the monitoring from April to September 1998 and a sediment field bioassay to check bioacumulation was performed. We present the first ecotoxicological evaluation of the mining spill in the Guadalquivir River, with reference to Tl, a little-known metal. Also, Pb and Cd data were compared to Tl during field sediment testing. Results show low levels of this metal in all of the organisms studied and they do not show any increase in the level of this metal, ranging from 40 to 90 ng g -1 , 80 to 210 ng g -1 , 15 to 98 ng g -1 and 75 to 125 whole body dry weight for Scrobicularia plana, Liza ramada (muscle), Crassostrea angulata and Uca tangeri, respectively. These are the first field data of Tl concentration measured using estuarine organisms. Field sediment toxicity test results

“…Ores in western Małopolska contain up to 90 mg Tl kg -1 (Zn sphalerite ores) and up to 1000 mg Tl kg -1 (Fe marcasite ores) (Cabała 2009). Despite its toxicity, Tl is a rarely studied metal and it has not been considered a pollutant for a long time in Poland (Borgmann et al 1998, Wierzbicka et al 2004. The aim of this study was to assess total Tl concentrations in soils developed at sites of historical Ag-Pb-Zn mining in Poland.…”

Abstract. The aim of this study was to assess thallium concentration in topsoil originating from sites of historical mining of Ag, Pb and Zn in western Małopolska (S Poland). Soil samples were collected from 63 sites, sieved, ground and digested in hot . In all studied soils they exceeded values typical for uncontaminated soils (0.02 to 2.8 mg Tl kg -1 ). This indicates that Tl contamination may threaten the environment and public health. Routine monitoring of Tl contamination in southern Poland is required.
