Identification of Heavy Metals found in samples collected from the

if one focuses on the atomic weight which will be more than 50, the list of heavy metals will contain all the elements starting from vanadium; but if one decides to use density as the main criteria which will be equal or higher than of iron, the list of elements will include lead, mercury, copper, cadmium, cobalt, but the less dense element tin will not be included into the list. on the other hand, heavy metals and their combinations can cause serious problems and diseases if they are accumulated in tissues being extremely toxic (lead, mercury). topic on heavy metals is quite interesting for the research, because enables to define the role of heavy metals for the existence of life and informs about the danger they can carry. is obvious that the process of research proposal writing is quite troublesome and requires much energy and time. he selected this project for his career application because, "the ideas contained within this proposal represent the essence of my research focus and educational philosophy.
