Inorganic and Radiation Analytical Toxicology Branch

The Inorganic and Radiation Analytical Toxicology (IRAT) Branch conducts research, develops analytical methods, and analyzes metals such as mercury (total and organic), arsenic (total and speciated), cadmium, lead, cobalt, tungsten, uranium, molybdenum, antimony, and other trace, toxic, and essential metals. For each of these metals, the Branch produces population-based exposure levels segmented by age, sex, and race or ethnicity. The Branch also collaborates with academic institutions and other partners, including state public health departments, on exposure studies and studies that examine the connection between exposure levels and health effects. IRAT also provides laboratory support for the public health response to radiologic threat agents.
