Abstract: Mercury is the most dangerous pollutant prone to the formation ofthe toxic forms. Therefore, the problem of cleaning mercurycontaminated areas seems to be very relevant. Numerous workshave been published on the study of mercury uptake dependingon the type of plants and natural conditions, but less attentionwas paid to studying the influence of element’s speciation ontheir accumulation ability. In the present work, the results oflaboratory experiments on the assessment of accumulationefficiency of white mustard growing in medium with artificiallyintroduced mercury species such as HgCl2,CH3Hg Cl and HgS arediscussed and bioconcentration factors were evaluated whilemaintaining plant viability. It was shown that methylmercury isthe most intensively accumulated specie while mercury sulphideis more imbibed than HgCl2during 3 months experiment in spiteof its negligible solubility in water. Based on the assumption thatthe cause of such a phenomenon is associated with thetransformation of mercury species in the process of the plantsgrowth, mercury speciation in the growing environment has beenstudied in dynamics and the results obtained confirmed thissuppose. It appeared that HgCl2and HgS are transformed intoother chemical forms.
