Because the layer of tin ore in the world is different and young people's teeth absorb trace metals in the environment, then the area where a person grew up can be distinguished through the analysis of lead in teeth, said geologist, George Kamenov. This study by the University of Florida.
"If you were born in Europe and then came the United States, then I will be able to know," said Kamenov. "I was born in Bulgaria, so I have a signal of Europe."
Identifying bodies
Kamenov said he has worked with law enforcement officers in certain cases, where the analysis of the teeth lead researcher can help narrow the focus of their attention.
In addition to assisting the government in identifying bodies, analysis of lead in teeth can help archaeologists find human remains in ancient times.
The impact of the use of leaded gasoline from 1920 to 1980 is also reflected in the teeth. This can help narrow the analysis of the age of the body, said Kamenov.
Identify the location of a person
Teeth can reveal whether a person spent many years in
United States or Europe, South America, Australia or other large areas.
In addition to lead, Kamenov said, the analysis of oxygen in the bone, which regenerate every seven to 10 years, can determine where people spend their time during the last decade.
Other chemical elements in hair and nails also provide information about the location of someone a few months earlier.
