“…Subsequent studies, however, paint a more complex picture with some studies indicating slow or fast re-oxidation or rates in between. Remobilization of reduced technetium during re-oxidation events has been addressed by Ashworth and Shaw (2005), Begg et al (2007), Burke et al (2005Burke et al ( , 2006, Morris et al (2000Morris et al ( , 2008. The main theme of these papers is that technetium fate is intimately related to iron and sulfur geochemistry and these, in turn, are strongly governed by microbiological processes.…”

“…In Tc state, in soil, they play important role in microorganisms, as well as in redox soil potential (Tagami and Uchida 1996). Reduced Tc forms such as Tc(IV) are bounded to soil particles, and because of this, they are less bioavailable (Ashworth and Shaw 2005). The role of anion transport proteins is still discussed (Tagami and Uchida 2005).…”

Uncommon heavy metals, metalloids and their plant toxicity: a review

Heavy metals still represent a group of dangerous pollutants, to which close attention is paid. Many heavy metals are essential as important constituents of pigments and enzymes, mainly zinc, nickel and copper. However, all metals, especially cadmium, lead, mercury and copper, are toxic at high concentration because of disrupting enzyme functions, replacing essential metals in pigments or producing reactive oxygen species. The toxicity of less common heavy metals and metalloids, such as thallium, arsenic, chromium, antimony, selenium and bismuth, has been investigated. Here, we review the phytotoxicity of thallium, chromium, antimony, selenium, bismuth, and other rare heavy metals and metalloids such as tellurium, germanium, gallium, scandium, gold, platinum group metals (palladium, platinum and rhodium), technetium, tungsten, uranium, thorium, and rare earth elements yttrium and lanthanum, and the 14 lanthanides cerium, dysprosium, erbium, europium, gadolinium, holmium, lutetium, neodymium, promethium, praseodymium, samarium, terbium, thulium and ytterbium.
