Today, industrial and scientific activities employing radioactive elements produce considerable amounts of waste that may pose a risk to the environment and to public health due to their chemical and ionizing properties. Understanding the transfer mechanisms of such anthropogenically derived elements in the environment and their possible accumulation in living organisms is necessary for the assessment of their environmental toxicity. In this context, detailed knowledge on transfer mechanisms of heavy metals, metalloids and radionuclides from an external environment to living organisms, as well as transportation to target organs or cells are important. Similarly, the impact of the the physico-chemical form (speciation) of such heavy metals and radionuclides may have a high impact on their mobility and toxicity, and must be taken into account when their impact on the environment and public health is assessed.
On a long term, our aim is to develop technical solutions that prevent the accumulation of potentially toxic elements in a wide range of organisms and their sensitive organs, and to combine this knowledge with remediation technology that can reduce the general environmental impact and critical transfer processes if needed. Results from this field of research will surely represent major economic and public health assets to the society in the future.
