    Note: These rankings do not cover all chemical releases reported to TRI - they only include chemicals that possess risk scores. As a result of data gaps or modeling problems, not all TRI chemicals possess the information required to weight their mass release by toxicity and exposure potential. Dioxin compounds, for example, are not included in these rankings. TRI chemicals that lack risk scores should not be assumed to be safe.
