Welcome to the web site of the bone lead measurement facility at Mount Sinai. At this site you will be able to learn about the technique of X-Ray Fluorescence, that we develop and use to measure long-term lead stores in people; and about the environmental toxin lead.

Our Mission

            Our goal is to learn about the associations between the amount of lead in our bodies and the health effects of lead.


The Bone Lead X-Ray Fluorescence testing facility (in the Department of Preventive Medicine at The Mount Sinai Medical Center in New York City) is one of the country's leading centers for a novel, relatively new technique for measuring long-term lead exposure.

Primarily a research group, in vivo human bone lead levels are measured non-invasively with a technique called X-Ray Fluorescence that is both developed and used here.

Volunteer subjects are measured for federally funded research studies. Also measured are people who are referred to us by physicians because they have symptoms of lead toxicity or are concerned about lead exposure they may have suffered in the past. The information obtained from bone lead measurements can provide evidence of historical lead exposure, in the absence of documented exposure.
