Scientists focus on heavy metals in combat vets

FROM ARMY TIMES...

Researchers at Stony Brook University Medical Center in New York have determined that a soldier who deployed to Iraq is now carrying particles of titanium, iron and copper in his lungs.

In a letter published this month in the Journal of Occupational and Environmental Medicine, Stony Brook Assistant Professor of Surgery and Medicine Dr. Anthony Szema wrote that samples of a service member's open lung biopsy were found to contain the heavy metals.

Open lung tissue biopsies done on troops who deployed to Iraq and Afghanistan have been shown to sparkle with crystalline material, as noted by researchers Dr. Robert Miller of Vanderbilt University and Dr. Matthew King of Meharry Medical College, Nashville, Tenn.

But until now, scientists have not determined exactly what the particles were.

"I was at a barbecue speaking to my colleagues and learned that a method to identify the material was available just down the road at Brookhaven National Laboratory," Szema said.

He sent the biopsy slides to the laboratory, which used its National Synchrotron Light Source, a facility-sized machine that uses bright beams of x-rays, ultraviolent and infrared light for research, to analyze the material.

"The patient had hot spots all over his lungs," Szema said.
