Trace Metals Unit - Biomonitoring Testing
Information on Biomonitoring Testing
The Division of Laboratory Sciences at the Center for Disease Control and Prevention (CDC) coordinates the National Biomonitoring Program (NBP) which offers an assessment of nutritional status and the exposure of the U.S. population to environmental chemicals and toxic substances. Worldwide, biomonitoring is recognized as a standard for assessing people's exposure to toxic substances and for responding to serious environmental public health issues.
The Trace Metals Unit tests for environmental metals such as lead, cadmium, mercury, arsenic, cobalt, thallium, beryllium, barium, and manganese which are all toxic to the body at certain concentrations. These metals are not essential or normal constituents of the body, but will always be present due to their existence in our environment. Exposure to such metals occurs through inhalation, ingestion, or absorption which leads to accumulation of these metals in the body.
The Trace Metals Unit performs metal analysis on urine, blood, and tissue specimens using inductively coupled plasma mass spectrometry (ICP-MS). Once the specimens have been assessed and accessioned, they are digested or treated with diluent and placed on the ICP-MS for detection and quantification.
