摘要

As part of its mandate, the Agency for Toxic Substances and Disease Registry prepares toxicological profiles on hazardous chemicals found at Comprehensive Environmental Response, Compensation and Liability Act, National Priorities List sites that have the greatest public health impact. These profiles comprehensively summarize toxicological and environmental information. This article constitutes the release of portions of the Toxicological Profile for Tungsten. The primary purpose of this article is to provide interested individuals with environmental information on tungsten that includes production data, environmental fate, potential for human exposure, analytical methods and a listing of regulations and advisories.
