MA data were used by New Jersey and Maryland to help guide and rank efforts to understand and regulate toxic substances in the environment. NATIONAL GOVERNORS' ASSOCIATION MASS BALANCE SURVEY The committee was aided by NGA in conducting a survey to obtain information from the states about their past or current mass balance data collection (Johnson and Gooch, 1989~.

In Rhode Island, certain industries are required to complete air pollution inventory questionnaires involving mass balance calculations. The questionnaire for degreasers and dryers, for instance, requires that industries report the amount of certain volatile organic substances purchased, the amount removed for disposal or reclamation, and the quantity recovered in carbon absorbers.

and so pioneered the collection of MA information. The New Jersey Industrial Survey Project In 1977, existing information on potential sources of exposure to toxic chemicals was evaluated thoroughly by the newly established Toxic Substances Program (now the Office of Science and Research)

The Maryland Toxic Substances Registry System Before Maryland had developed its Toxic Substances Registry System, Baltimore and its surrounding counties were identified by the National Cancer Institute as having elevated mortality rates for several types of cancer. Concerns were heightened by incidents involving accidental or uncontrolled releases of toxic substances from storage tanks.

SUMMARY The Maryland Toxic Substances Registry System and the New Jersey Industrial Survey together provided the model for the TRI. Both states claim that these MA data projects have benefited their regulatory and public health efforts by providing a focus and ranking within diverse strategies to understand and regulate toxic substances in the environment.

The experiences of New Jersey indicate that MA ciata can be important, in a qualitative sense, in developing, validating, and assessing information on toxic chemical releases. The New Jersey Industrial Survey provided a means to confirm in overall terms chemical release information obtained from other sources anti, in some cases, to provide insights into important, previously undocumented release pathways.
