What was the purpose of the tungsten study?
The study was conducted to assess the level of exposure to tungsten in three Nevada communities to determine whether or not the levels of tungsten measured in Churchill County (Fallon), Nevada, were unique. CDC conducted the study as a recommended follow-up step to the Churchill County (Fallon) environmental exposure assessment. CDC did not assess any potential health effects related to tungsten in this study. In August 2002, CDC nominated tungsten for study with high priority to the National Toxicology Program (NTP) [external link] of the National Institutes of Health. NTP is conducting the process of reviewing tungsten for its research agenda. For the latest progress on this issue, see The National Toxicology Program and Tungsten.
