Ruthenium is a chemical element; it has symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table. Like the ...
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life.Some metals are toxic when they form poisonous soluble compounds. . Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain for
Group 8 is a group (column) of chemical elements in the periodic table.It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). [1] " Group 8" is the modern standard designation for this group, adopted by the IUPAC in 1990. [1]
Roshydromet then issued a report describing a rise in beta activity of aerosols and surfaces at all monitoring posts in South Ural from September 25 to October 1, 2017. In two aerosol samples, an increase in Ru-106 activity was detected. On September 26 and 27, Ru-106 decay products were detected in the Republic of Tatarstan. On September 27 ...
A quantity of radioactive waste typically consists of a number of radionuclides, which are unstable isotopes of elements that undergo decay and thereby emit ionizing radiation, which is harmful to humans and the environment. Different isotopes emit different types and levels of radiation, which last for different periods of time.
In humans, heavy metal poisoning is generally treated by the administration of chelating agents. [71] These are chemical compounds, such as CaNa 2 EDTA (calcium disodium ethylenediaminetetraacetate) that convert heavy metals to chemically inert forms that can be excreted without further interaction with the body.
Yttrium can be highly toxic to humans, animals and plants. [10] Water-soluble compounds of yttrium are considered mildly toxic, while its insoluble compounds are non-toxic. [ 53 ] In experiments on animals, yttrium and its compounds caused lung and liver damage, though toxicity varies with different yttrium compounds.
The rate of ligand exchange for ruthenium complexes is relatively slow in comparison with other transition metal complexes. The range of these exchange rates is around 10 −2 to 10 −4 s −1 which is on the scale of an average cell’s lifetime, giving the drug high kinetic stability and minimizing side reactions. [1]
