Commission on Life Sciences & Committee to Evaluate Mass Balance Information for Facilities Handling Toxic Substances 
Tracking Toxic Substances at Industrial Facilities [PDF ebook] 
Engineering Mass Balance Versus Materials Accounting

In response to a congressional mandate, this book examines whether knowing the amounts of toxic substances entering and leaving manufacturing facilities is useful in evaluating chemical releases to the environment, waste reduction progress, and chemical management practices. Tracking of these substances with rigorous engineering data is compared with a less resource-intensive alternative to determine the feasibility and potential usefulness to the public and the government.
