Baby teeth from about 30 volunteers in Holliston showed a Boston researcher whether and when the children had been exposed to several different types of metals down to the week, even while the child was still in utero.

The method is one of the cutting-edge technologies that Claus and fellow researchers have helped advance while studying drinking water in Holliston for the past several years.
